[XP] Fans

Firstly I will put the link to my previous post so you can see what I need to do. http://discussions.virtualdr.com/sho...62#post1192062

I have my new motherboard, new processor fan and heatsink. I had intended to follow Trains advice by installing a case fan low at the front and another high at the back of the tower, unfortunately there is only one connector on the motherboard for a chassis fan :eek: Which position is optimal to place the one fan? Even with one chassis fan it will be an improvement to the old set up.

You really should follow Trains advise. Chassis fans can be powered by a 4 pin Molex connector (like the one on your hard drive). If you don't have an extra one to use you can get a "Y" adapter.

This is what you need, most case fans will come with one supplied:

By using the adapter, you bypass any possibility of having the fan doing any damage to the mobo because it drew to much current. Another plus for using the adapters.

:o I really should have looked inside the case fan box before pestering you :o

Thank you for the prompt replies, my case fan came complete with the necessary extra adapter/cable. I just didn't realise it was there in what looked like a blanking box in the packaging.

I will now take a few deep breaths and go ahead with the new motherboard installation ... wish me luck?

Take it easy, watch what you are doing and things will work out just fine.

:( ok I'm back to square one.

I installed new motherboard, complete with new ventillation system, all seemed fairly straight forward. BUT..... I am in exactly the same position as I was before .... a computer that does absolutely nothing. The power supply seems to be fine, all fans are functioning normally, the dvd drive activates and looks for a disk as per usual. There are NO bios beeps and no noise from the hard drive at all ( I really miss those graunchy sounds it used to make). I have checked the connections to make sure they are all clean and snug. I am now a lot poorer and still have a tower that is not sure if it's supposed to be a computer or a toaster :( .

Any idea where I go from here?

Remove all pci cards, leave your video card in, and try booting?
What happens?

If nothing , then try to boot up with only the floppy drive connected.. Yes disconnect the cd/dvd device and all hdds.
What happens?

Did you make certain that you plugged the sqare 4-pin 12 volt connector? If you don't hook that up then you get exactly what you are experiencing.

hi,

yes supersparks, I did make sure the square 4-pin connector was in place (phew)

ok.... I didn't install my agp graphics card at all, thought I would use the motherboard onboard graphics till I was sure everything was working ok. No pci's attached either.

I just disconnected all drives except the floppy and had the same result ... power supply working, fans all functioning and nothing else ... not a whisper .. not a clunk :(

Have more than one stick of ram?

Only use one and if that does not work swap around.

If you have, or can borrow, a multimeter, here's how to test the power supply:

Testing PSU Voltages

ATX Power Supplies

Trigger Power Supply for testing

In depth look at the power supply

Or alternatively you can buy a proper PSU tester, they don't cost much:

PSU Tester

ATX12V PSU Tester

ok ... checked with one, both, the other one, and a completely new ram stick and still no change.

I will have to take a look at the links posted by SuperSparks later tonight, I've just run out of play time now :(

I'll get back to you, but if you have any more ideas please let me know?

Virtual Patient

Post the make and model of the mobo please.

That is the motherboard I just installed. ASRock P4i65G, I hope that is the info you asked for?
