[RESOLVED] BIOS NOT LOADING

Hi guys its me again, the computer was running perfectly well since I changed my VGA and PSU. Yesterday after playing Red Faction Guerrilla I switched off my computer and this morning turned on but somehow the computer got power but does not load the bios. The speakers are working and there is no beeps of any kind. I also connected my Corsair PSU onto a PSU Tester and shows as normal. I took the Mobo battery and the jumper out to clear up the CMOS and also tried changing the jumper to clear it up. Both hard drives have been connected to my external case and hooked up on my Laptop and no viruses were found. I also tried to unplug everything from my Mobo and connecting one by one to double check if would work. I tried all sets of connections to the motherboard and even only the power on it would not work. The computer has power because I see VGA light flashing when starts and all fans running with power. My case led lights are on but the hard drive is always off. I have a suspicious could be my Mobo or CPU but before rushing to conclusions I need to know to get a replacement under its warranty. I really appreciate for your help once again. Thanks!!!

Try installing a new CMOS battery.

Make sure that the ATX 12volt connector is plugged in, and test it with your tester, as you'll get the symptoms that you describe without that.

Is it possible that a CMOS battery could have been causing that? It seems such a big deal for something so small like that. I just mean because the BIOS is not even showing up and no beeps whatsoever. :D

Sure is possible. Whether something is small, large or medium has nothing to do with it--if anything is not what it's supposed to be it won't work. If you have a meter measure the voltage--should be 3 Volts.

I am getting the battery in two days and I will keep it posted for any updates. Thanks Mate. :)

OK--there's no guarantee this will fix your problem, but, as it's a possibility and they are so inexpensive it's worth a try. If it doesn't do it at least we can eliminate it from the troubleshooting.

Hi there, just tried the battery today and it is not the problem. Nothing changed, the computer has power on it, i hear and see all fans blowing, vga flashing once power light when started. When I switch on my PC I also can see the DVD-rw drive flashing its lights like if its reading something than stops. I believe it is normal reading when starting. Funny thing no memory beeps nor BIOS. Could it be a dead CPU or MOBO??? Because both are still on the warranty but the problem is that I need to know each one is faulty. I have a guess might be the MOBO. Plz guys gimme some light about this. :)

Most of the time, it will be the motherboard that is faulty. If you were overclocking, then the CPU could have failed, if not then that is much less likely unless the heat sink and fan were not tightly attached.

I agree, it is very rare for a CPU to fail. Motherboard failure, on the other hand, is distressingly common :( Unfortunately there is no way to be 100% certain, but on the balance of probabilities it is far more likely to be the mobo.

Does your Monitor show anything (like a VGA or DVI box or any other writing) moving around the screen? If you see a box like this if your monitor is OK. If you don't see a Box or writing the monitor might be the problem.

Can you hear the Hard Drive spinning? Put your ear up close to the Hard Drive to see if you can hear it spinning (make sure to have the computer turned on) (don't touch the hard drive)!

Is the Fan on Top of the Heatsink spinning? If not make sure it's plugged in to the motherboard s 3 pin connection marked for the heatsink fan. If it's plugged in, try another 3 pin connection on the motherboard!

If these three steps don't help, I'd go to the 15 steps below!

1. Unplugging everything including the Heatsink and CPU
2. Put CPU back into the CPU Socket
3. Apply small thin layer of Thermal Grease to the center of the CPU
4. Put Heatsink on top of the CPU and secure the heatsink (Plug in the heatsink's Fan to the motherboard)
5. Put 1 stick of RAM into the #1 Slot (usually nearest the CPU but check MB Manual for correct slot and also the number of Sticks RAM needed to power the computer) (make sure the tabs click into place holding the RAM in place)
6. Put your Video Card into the PCI-e slot (usually the one nearest the CPU but check the MB Manual to be sure)
7. Plug in any power connections needed for your Video Card (depending on the card it may need up to 2 power connections)
8. Put the Hard Drive back in the correct place inside your computer case, fasten with screws.
9. Plug in the SATA or IDE connection to your hard drive and then to the Motherboard (SATA 1 or IDE Primary)
10. Plug in a power connection to your Hard drive
11. Plug in the PSU's 2 connections to the motherboard (24 pin and 4 pin for newer computers) (1 x 20 pin for older computers)
12. Plug in Case Front Panel Connections to the Motherboard (Power SW, HD LED, Reset SW, Speaker etc...) (your external speakers will not usually beep if the Video Card or RAM isn't working properly so the Case Internal Speaker must be plugged in) (refer to your motherboard manual for connections)
13. Make sure your Case Fans are plugged in
14. Plug in Keyboard/Mouse, Plug in Power to the PSU and Wall, Plug in Monitor to the Video Card (VGA, DVI or HDMI) and Power Connection to the Monitor (then turn it on).
15. Once all of this is completed try starting the computer.
a. If it works Unplug Power then install 1 stick of RAM at a time starting the computer each time to make sure it still works.
b. If it doesn't work Unplug Power and Remove the RAM and replace with another stick. Plug in and restart to see if it worked.

Hi there, I have done all the steps you mentioned about and the PC is still not working. There is power on all components, CPU, Fans, HDs, VGA, etc. I have tested different memory sticks, took everything apart and put it back in. New thermal grease, cleaned all fans, basically everything that could have been done, I did. I strongly believe it is a Mobo problem and I am already on the process to get a new Mobo or a refund to buy a new one. Anyway, I promise to keep it posted and as soon as the computer is back running I will notify you guys about. Maybe this incident could help somebody else out there! Thanks mate!!!

Hi I really never been into over clocking, I like to play it safe (lol). The computer just went half dead after some gaming session. I strongly believe is my stupid MSI Mobo. Thats why I am going back to ASUS. ;-)

Yeah I agree with u , everything leads to a Mobo failure. I am not a professional technician but I have my leads about that as well. The way it happen I blame on my rubbish MSI Mobo. I have always been an Asus fan boy but somehow I got into MSI (I know they also make good stuff but after this will be a good time until I leave Asus behind again). Anyway thanks, I will keep it posted as soon as my new Mobo, AM3 CPU and Corsair Dominator Memories arrive. Thanks!!! :D

Have a look at Gigabyte, IMO they are even a little better than Asus.

Hi there, I finally bought myself new components. I got a new AMD 965 Black Edition, DDR3 Corsair's Dominator at 1600 MHz (8 GB) and a new Mobo (Asus m4a785td-v evo) and my computer is up and running fast again. I tested and then sold my old processor (9850) on eBay, the guy who bought it is quite happy about. My memories (8GB OCZ Gold PC6400) have been tested and left on eBay for bidding. My old MSI Mobo has been left on the corner waiting for a RMA request to get a new one or refunded, after triple checking it I've found that is faulty and does not work on any computer. MSI just contacted me that shortly they will process my request and gimme a RMA code to get a new 1.

I just want to leave this message for anyone out there that might face the same problems. As I suspected and everyone else who helped me, it is really a Mobo problem. All the power running but no sign of memories beeping or any chance to load up the BIOS have all being leading to a faulty Mobo. I want to say thanks to everyone and say this is the best forum I have ever been. Well done guys!!! :) :D :)

You're very welcome. I'm glad you got it all sorted out in the end :) :)

I'm glad to hear that it was just the motherboard. A few years back I slipped with a screwdriver and shorted (fried) my Asus motherboard. At the time I was a little low on cash and purchased an MSI Motherboard (Top Of The Line MSI) for a replacement. I have had MSI Video Cards in the past and they have worked without a problem so why not use their motherboards? It ran fine for about a week and then all of the sudden everything stopped working. I tried my daughters CPU and it wouldn't work on the MSI board either (it wouldn't work on her motherboard when I put it back in either, this CPU fried her motherboard once I put it back in her computer). I took the MSI Motherboard back to the place of purchase and they wanted to give me another MSI as a replacement. I refused and they did finally replace it with an Asus. I wish I had asked them the week before how much the Asus was, it was only $3 more than the MSI I had purchased and I could have afforded that! Anyway a long story short, the MSI board fried my CPU & my daughter's CPU & motherboard. It also managed to do something to my Mirrored RAID set and I lost all of my programs & info (the Seagate drives were still ok).

That MSI motherboard cost me 2 CPU's and 1 motherboard and all the time for my data loss. Never again will I use an MSI Motherboard! I'm with you in thinking I'll stick with Asus.

Also a few years back Epox made the hot motherboards for gamers. I built a computer for my brother so he could do some gaming and he insisted on the Epox motherboard. I'm not sure if I should blame his problem on the motherboard or PSU. I wanted him to buy a reliable PSU but he didn't want to replace the PSU that came with his case. Anyway, we had major problems with the computer after a couple days. I finally talked him into purchasing a good PSU, but by then it may have damaged the motherboard or maybe the motherboard was bad from day 1, who knows? My point, I've heard really good things about Gigabyte Motheboards, the same as I had with the Epox Motherboards. Should I stick with a Motherboard I've come to trust or should I try my hand at switching???? I think I'll stick with what works for me! BTW, the Asus Motherboard I fried at the beginning of this post was totally MY FAULT, not the motherboards!

Everyone has different luck with motherboards. MSI is my good one and ASUS is the horror story.

Hi there, I am sorry for what happened to you regarding Mobos. Going to the issue of MSI, Gigabyte, Epox or Asus I have been using Asus for a long time now and I can proudly say this that I never had a problem. My fist MSI Mobo was working for less than a year and comes out faulty. I do not know if was just bad luck for both of us or merely a coincidence, either way I will not go back to MSI or any other Mobo manufacturer. As far as I know Asus is one of the best manufacturers I have ever seen and judging by the new upgrades they are staying on the market for good. I only buy Mobos from Asus, memories from OCZ or Corsair (so as PSUs), VGAs from XFX, Asus or BFG and CPUs from AMD only (intel is ripping off its customers - yeah I know they got the best processors but I will not pay the price for it, its extremely overcharged). I had a incident with a MSI Video Card that cost me A hell lot of money. I had to replace almost all my components just to realise the video card was unstable blowing up fuses on my PC & Power Lead. It is just like you said " I think I'll stick with what works for me!" :D :D :D

Funny thing, to me is completely the opposite. I had a Mobo and VGA from MSI and they both gone Faulty. :eek:

All of my own computers have been built with Asus Moterboards, The MSI board was a replacement for the Asus board I fried (never again).

If I build one for someone else I will recommend Asus but that doesn't mean that's what they'll go with. I have built a lot of systems with a Bare Bone purchase which usually didn't come with Asus motherboards because of the MB's price difference.

These are the parts I usually use in my own systems:
Asus Motherboards (I've never had a bad motherbaord)(I've been using Asus since P2B motherboard with an Intel PII 350)
AMD CPU's(I mainly have used AMD's for my Desktop Computers) (I have used Intel from time to time but always go back to AMD)(Started using AMD's with an AMD DX5 133MHz)
G.Skill RAM (I've never had a bad Stick of RAM & it has been compatible in my 4 Desktop (AMD) & 4 Laptop (Intel) Computers)(Been using G.Skill since my AMD Athlon XP 2600+)
XFX Video Cards (nVidia)(don't care for ATi Drivers)(First XFX Video Card 7800GT)
Seagate Hard Drives(Started using Seagate Hard Drives after I had lots of problems with WD's 40gb drives)(I have 1 x 80gb, 2 x 120GB, 2 x 500gb, 2 x 1tb and 1 x 320gb (laptop 7200rpm) all Seagate and all still running)

Asus and Gigabyte are the same company these days - I suspect that the only reason for keeping the two separate brands is because of the sort of brand loyalty we are seeing here (I feel the same way about Gigabyte boards :D ). As far as quality is concerned, I've never found anything to choose between Asus and Gigabyte, and I'm happy to build with either. I usually find that the Gigabyte boards have a slightly better feature set than Asus though.

Well at the end is not about the brand but if really works. I had good stuff before from MSI, actually, a few years back both Asus and MSI were my favorites. Only recently I had a lot of issues with a Mobo and VGA card that made me spent a hell lot of money. It does not mean that MSI is rubbish but once you have problems you try to avoid future regrets. Anyway at the end of the day as long it works for you and your happy with it thats it!!! Thanks 4 the message mate!!! :D :D :D

How true that is. I still won't buy Maxtor hard drives or anything made by Logitech because of terrible experiences that I had with them years ago.
