Hello all, my computer's been giving a little bit of a problem recently.. It first started with a few blue screens then eventually I couldn't power up the computer. The lights would go on then off. Draining the power supply then turning it on again wouldn't work so I let it rest for a day.

The next day, it booted successfully to default voltage and frequency as it was previously overclocked. This overclock has been stable for over a year without problems so it struck me odd how this could suddenly happen. I reverted back to the old overclocked settings and it got stuck in the lights on/off state again. I discharged the PSU, turned it on again which managed to POST at default values again. Now I'm posting here with this computer.

Few things to note:
1. Suspecting that it was PSU problem, I measured the +5v and +12v lines through a 4 pin molex and it checked out fine. Should I also check the readings on the 24pin cable?
2. My motherboard bios has a revert to default feature that happens whenever it fails to boot, however, this time the problem seems to be so bad that it can't even revert.

System specs:
Intel C2D E4300
Gigabyte GA-965P-S3
Thermaltake Toughpower 750watts modular supply
2x Kingston valueram 667 1GB
2x Kingston hyperx 800 1GB
Asus 4870 DK 1GB
WD 640GB AAKS

Since I raise my voltage quite a bit with the overclock, I'm thinking the power supply could be the culprit when trying to output more power. My next main suspect would be the motherboard.. Any suggestions on what I should do next? Thanks!

what were your voltages. and how much did you overclock your cpu/ram. sometime things just degrade if you use too much voltages.

if your psu never degrade, it should be ok.

[Ra|ne]

1.36 on VCore
+0.1 on FSB
+0.1 PCI-E
+0.1 on RAMS
+0.2 MCH

Rather conservative voltages, just that it's significant from stock voltage..

[Shrek]

you mean +0.1v?

[Ra|ne]

oh yeah woops.. sorry lol

[Shrek]

wat are your fsb and ram speeds?

[Ra|ne]

Hey, sorry for the really reply. Been kinda busy and didn't remember it offhand.
FSB and RAM speed 290/580 respectively.

Another thing I've observed is that my computer blue screens on shutdown and almost hangs all the time when torrenting and left to idle.
