Re-boot Problem

[ComputerDoc2]

I have been having this reboot problem on a new build, I have a K8N Neo Platinum 754 and the AMD 64 3400+ with a nVidia 6600GT video card, 2 CD/DVD's and 4 HDD. My Antec PS is 400W. Could this (PS too small) be the cause of the random reboot problem?

Please provide a detailed description of the reboot problem. Thanks.

It's a reboot....I can be working in Windows and bam, remoot.

Two cent...
My Iwill DK8n, dual Opteron 246, 2 gig ram,cd, floppy, scsi raid , 7 disks, pc power and cooling Ps, uses 325 average 375 max watts. Some motherboard are unusually finicky about power requirements and fluctuations. I have seen bad ram and CPUs cause this. Is the PS on the board manufacturers compatibility list, odds are it is the PS.

The reason why I asked for a description is because there are 2 general types of reboot problems:
(1) Manual
(2) Automatic

So if yours is an automatic problem, then in addition to technome's suggestions, it can also be caused by the following:

-Everything not completely seated on the motherboard.

-Overheating
If the system temp gets over 45 deg. C, then make sure the computer's fans are running, the vents are open, the computer is not located in an enclosed space or near a heat source, and there is no internal dust build up.
If those are ok, then remove the computer's cover, and run an external fan. If this fixes things, then install additional case fans. Recommended locations are lower front and upper rear of the case.
If the CPU gets over 60 deg. C, then make sure there is thermal compound between it and the heat sink. If that's ok, then replace the compound with Arctic Silver3.
If no luck, then install a higher capacity heat sink fan.
If still no luck, then replace the heatsink with a more efficient unit.

-Bad video card.
Make sure it's fully seated, it's fan is running, and its heatsink is securely mounted.
If those are ok, then swap it out with a known good card.

-Bad MB.
Check for bulging, leaking, or ruptured capacitors.
If they look ok, then swap it out with a known good MB.

-IRQ conflict with a network card.
If no problems show up for the NIC in Device Manager, then remove it from DM, shut down, uninstall the card, and restart.

-Viruses and spyware.

-Kazaa.

As I said before, this is a new build, and a new load of windows, so I don't think a virus or spyware and kazaa are a problem here. The video card came out/off of the old mobo and is working, but I'll reseat it.

As for the CPU, it is a retail box set and came with a heat sink and fan. No dust in the case and it is sitting in the open and the door is off.

I'll try reseating the RAM.

If you've been browsing the Internet and opening e-mail, then the cause can be a virus or spyware or both, new build or not.

Also, run an external fan with the door removed to be sure that overheating is not the cause.

Thanks for all of your inputs, I replaced the PS with a 480 watts, and it works like a champ. I guess the AMD 64 and the 6600GT card are a real power hogs.
