Random "Reboots"

[Gorbachev22]

Howdy folks,
I recently upgraded my desktop to the following:
ASUS P5Q Deluxe
Corsair TX750W
2Gx2 OCZ 800
2X Radeon 4850
Q6600
SB x-fi


It seemed to work fine for a few weeks until the computer randomly reset a few times. It has gradually become more and more frequent. The reboots happen while gaming, in loading windows or any other action. Sometimes it also won't start upon hitting the power button. However, if I hit the top of the case (at the front away from the PSU and the hard drives) the computer will start up. Any shaking to the case can also cause it to reset. Any ideas what the problem is?

Goddamn those are odd problems.

Hit up the Basic TroubleShooting guide sticky in this forum for an idea of where to start fixing.

Though my guess is improper wiring. Reassemble the PC outside of the case. Leave the motherboard on the motherboard's box. Jump the two power pins with a screwdriver on the motherboard to start the PC.

And to rule these out:
Download Memtest+ v2.01, unzip it, burn the ISO file to a CD, and then boot from it, just like you would do with the XP install CD. Let Memtest+ run for at least three hours on each stick of RAM separately. Go for a full 24 hours if you want to be completely sure that the RAM is not a problem. If you start seeing errors, than your RAM is bad.

Download the CD image of Hitachi Drive Fitness Test, burn the ISO file to a CD, and then boot from it, just like you would do with the XP install CD. Test the hard drive and see if any problems are found. DFT will run on most manufacturers' hard drives. Alternatively, you can use Seagate's SeaTools for DOS to test a Seagate or Maxtor drive. For a Western Digital drive, you could use Data Lifeguard Tools for DOS to test a Western Digital drive.
