PC Randomly Shutting Down

tsinc80697 · 28 Jan 2008 at 00:12

Its been doing it about once a day or less than that, really randomly, no matter what I am doing.

Will it be PSU related or could it be anything else?

The PSU is a 480W Jeantech one, not that good as far as I know, but forking out £80 for a PSU and it turns out its not will annoy me!

Thanks

Spec -

Q6600 @ 4hgz
4gb ballistix
3 x 500GB HDD
1 x DVDrw
1x water loop
8800 GTS 512mb

has this been happening since you built it ? or only just started ?

judging by your spec i would say that jentech is running close to its limit

I cant remember if it happened before adding the water loop but Im pretty sure it was fine with a 640mb GTS in the system and another HDD instead of the water!

Random reboots can normally be attributed to Northbridge voltages (or temp) or a dodgy driver. Have you updated any software recently?

Try backing off the overclock for a moment to see.

I agree that it might be a good move to invest in an corsair HX520.

Put the clock to 1.4v CPU 30001mhz, droppd NB voltage and PLL. Was on fine overnight playing Scrubs for 7hours, used it for 10minutes this morning and it turned off, no w on my mac

Are all your fans still spinning as they should be?

When the PC is on they spin fine, ut when it turns off it turns everything off until it seems to cool down, sometimes its 10seconds and sometimes its a while. Last night took about 25minutes

Could be the PSU overheating then? But I would have expected roughly the same amount of time for it to cool off so does sound weird.

Lowered the overclock and volts and it hasn't died since!

Not sure whether its the motherboard not handling the volts or whether the PSU can't handle outputting that amount over a long period of time!

I had/have (not sure if it is right yet) this problem over the last few days (see my thread below) and bumped the RAM and NB volts by 0.1, and am now 3 hours Prime stable and it all seems fine.
