spontaneous reboot

[genemd]

Hope someone can help. Not sure where to start. ? memory, board, PSU, heat, SLI?
Here is the problem ( my setup is in my sig). New build - no problems installing OS, RAID 0+1, or booting up, no OC tried yet. System seems stable for a while - in fact can leave running with no load on CPU for very long time. Baseline CPU temp is 45 C (seems high to me). Once I start putting some pressure on CPU, temp goes up of course, usually around 52-53 with 50% CPU utilization. Have got it up to almost 60 with full CPU utilization for short period (again, seems high). Will tolerate this for awhile, 10-15 minutes, then I get complete shut down and auto reboot. Once this cycle starts, it will boot up and start loading tray items but will not finish, shuts down and reboots again. If I leave machine off for awhile, I can reboot with no problem and it will stay on again until I start playing around with programs then above cycle repeats. Any ideas on where to start? I'd love to get back to HL2 but I haven't even attempted yet. I am running the 02 bios and 66.93 nvidia drivers (tried the 72.14 no diff). Is this a heat problem, PSU prob, bios issue??? any thoughts much appreciated.

I've seen PSU units cause this problem.

How about taking out all the non-essential things (like 1 or 2 hard drives instead of 4, zero optical drivers, and 1 stick of RAM). Still happens? 1 video card. All good? Add parts piece by piece until you isolate the issue. If it just seems to happen when you have all the crap in there, then I'd go with gsparesa and get a bigger power supply. I would think that one would be fine but you have a LOT of stuff in there.

Well, the answer is the PSU. I ordered an OCZ Powerstream 600 and plopped it in today. Have been running over 3 hours now, no problems. Have played HL2, Farcry, Rome Total War. Absolutely solid. The OCZ is an awesome unit, built like a brick shouse- polished exterior with green LED's to indicate when power rail voltages are within spec and adjustable dials to increase or decrease voltages. As an aside I also put in the Thermalright 120mm heat pipe with a 120 mm hsf. My CPU temp is now 35c, maxes out at 45c with everything blazing. Could have been a bad install of the original HS by Monarch but it looked alright when I took it off (heat pad, not paste). The Thermalright is awesome, takes up 1/2 the board but fits OK - does make the atx 12v slot on the mb and the pins to the left of the EZplug a bit difficult to reach. I'm grinnin'.

It's your psu. It's only 18a on the 12v and 30a on the 3.3v. You guys got to quite buying "spiffy" and start thinking about a real psu.

Damn. I had this open while I was reviewing that spiffy Thermaltake unit you had in there.
