System Turns Off

[dbd_r]

Hello all,

I'm somewhat of a computer guy myself, but my available trouble shooting time has vanished with the arrival of my daughter 4 months ago. If it would not be too much trouble I would like some suggestions.

My computer just completely shuts off while playing a game, either DDO or WoW.

A brief outline of my computer: (it's 6 months old and I built it myself)
Win XP pro all updates installed (Norton internet security 2006)
AMD 3500
Asus Mobo non-sli
600 W power supply
2 Gig Corsair ram (should have went value)
300GB Segate HD SATA 3G/s
Asus 7900 GT Top 256 mb video card

Here's is what I have done so far:

updated the BIOS
installed the most current video driver
re-installed direct x 9.0
Purchased an installed a Zalman VGA cooling fan which dropped my GPU temp from about 55 C to 43 C with max load.
I RMA'd my video card twice thinking that was the problem

I thought it could be heat, but my CPU never breaks 40 C, my system/mobo also never breaks 40 C, and my GPU never breaks 45 C, so I'm guessing it's not heat.

I am planning on running memtest soon.

Any other suggestions?


Thanks,

Randy

Sounds totally like a bad PSU. It's either that or a failing component on the motherboard.

I'd see if you have a spare PSU you can try, or RMA/replace the one you have. I'd also inspect the motherboard for any "burned" spots or bulging capacitors.

Thanks

I have the 400 W PSU that the case came with. I'll try that.

Memtest86 sucessfully completed 4 times in a row, but I'll let it run all night just to make sure.

Thanks again,

Randy

That may not be up to the task.
What make is the 600 watt and how many amps on the 12V rail?

Psu

I have a coolermaster extreme power 600W PSU

+3.3 V / 28A
+5 V / 30A
+12 V (1) / 18A
+12 V (2) / 18A
-5 V / 0.8 A
-12 V / 0.8 A
5Vsb / 2 A

I actually could not find my old 400W PSU, Should I try to RMA this one or just pick a new one up at the stoer to test with then take it back?

Thanks,

Randy
