Overheating?

[Deathscythe_Hell]

I somewhat recently upgraded my desktop computer significantly. However, I've been having a rather significant problem since I upgraded it. I can use the computer without any problems for quite a while, but eventually the computer will automatically restart, and then refuse to post(will instead post an error).

I'm guessing the most likely problem to cause this would be overheating, but I'm not completely sure on that, and figured I would see what other people thought. I have one case fan in addition to the power supply's fans, but I'm not sure that is sufficient with the core 2 duo cpu and geforce 8600 gts video card.

Although it probably not related, my video card also said that it is not recieving sufficient power from the power supply, so I will probably have to replace that anyways.

If your PSU isn't powerful enough for one piece of hardware the entire board suffers from an imbalance of power. I'd start with the PSU and if that clears it up you're good to go. Share your specs on your computer and the size of you PSU. We'll be able to help a lot better with that info...Jazz

I believe it is either a 350 or 400 watt psu...probably 350, and somewhat old.

Other specs:
Intel core 2 duo 2.66 ghz
2 gb DDR2 ram
Geforce 8600GTS 256mb video card
Asus Striker Extreme motherboard
1 ATA100 hard drive
1 SATA hard drive
1 SATA dvdrw

I would think it's your power supply. You can't run a machine like that on a 350 watt, especially if it's an older one probably caked with dust. I also checked the requirements needed to run the video card of yours:

Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 18 Amps.)
Minimum 450 Watt for SLI mode system.
(Minimum recommended power supply with +12 Volt current rating of 24 Amps.)
An available 6 pin PCI-E power connector (hard drive power dongle to PCI-E 6 pin adapter included with card)

Take that into consideration.

Hmmm, I probably should have checked the psu requirements for the video card before ordering it so I could have gotten a new psu at the same time. Ah well, they aren't too expensive. Will try a 450 and see if I still have problems with it restarting and then not posting.
