If the power supply was a Bestec, then both the motherboard and power supply are fried. You will need to replace both. You may have trouble finding a replacement motherboard that can use the existing CPU and memory, so you may have to replace those as well.
Power Supply - $40
Motherboard - $55
Memory - $25
CPU - $65
Total = $185 + shipping
New PC - $300

If your PC is turning on, it shuts its selff off as if going into a perm sleep mode there are few issues!
1) Power Supply could be bad, if it is replace ASAP or it can burn out you MB and nearly every other component on your PC!
2) Capacitors! (This is what my issue was) check them all over your MB! They are (in most cases) little black tubes with a smooth top.
Should the sides be bowed outwards or the top thats supposed to be flat are now bowed up as well or gunk is comming out of any part, thats a blown capacitor.
On my mothers PC she had 13 bad capacitors, also someone said that bestek (the power supply company) was a peice of garbage that Emachines and few other companies (usualy the cheaper PC companies) use.
This power supply on many forums across the Internet have proven time and time again that this brands power supplies often cause as surge before it dies (Its been known to die within 6 months of a barnd new purchase) causing your MB, Grap card and alot of other components to burn out, in my case it was the capacitors.
I urge you to look at your PC right away, if your supply is from Bestek get your asses to CompUSA or Bestbuy and grab a new one fast or your PC could be completly shoot from it.
In my mothers case, the Power supply burnt out, 13 capacitors were caused, the MB was shoot and the HD was destroyed! Basicly....a new PC was needed!
I wrote to Bestek in regardes to the issue, they only say over and over
"Dear customer, we are sorry that your personal computer has failed on you, at this time our records show our AC Power supplies to be without flaw. Your PC may have surged back the power supply (Doubt it since the PC dont have power, the power supply does(Then again I could be wrong) or your AC outlet my have caused a spike within the Power supply causing your PC to burn out.
We regret to inform you that at this time no payment can nor will be made for the loss of your PC. please see our customer satisfaction page if you should have any other questions.
Thank you"
Well there ya go! if ya got it, loose it ASAP and ask your PC manufacture to replace the drive as its most likly a lemon!
My sister's PC has the same problem now. Can you tell me please what could caused the leaking capacitors? Is it temperature, voltage or the other problem perhaps?Quote:

A lot of them were caused by a bit of industrial espionage that went wrong. Somebody stole a formula for making the electrolyte, but they didn't realise that it wasn't the complete formula. The formula that they ended up using worked OK for a while, but did not age well, and led to all the problems. As jdc2000 said, in the latest equipment it is no longer an issue.
