New Build Freezing Intermittently

[Zontar]

Well, this is a rather frustrating problem. My new build is freezing randomly, probably about after seven hours or so of being on. I don't know how to replicate the freezing, it's completely random...and leaves nothing in the error log after I reset.

So, where do I start here? RAM? CPU? Video card? Case short? Bad motherboard? Right now, I'm attempting to upgrade the video card drivers...I'll report back shortly as to whether or not that remedies the problem.

[Testing the RAM]
Download Memtest86+ v4.00 or whatever the latest version is, unzip it, burn the ISO file to a CD, and then boot from it, just like you would do with the XP/Vista install CD. Let Memtest+ run for at least three hours on each stick of RAM separately as well as test the RAM all together. 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 defective or you have incorrect settings for the RAM.

[Testing the Hard Drive]
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/Vista 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.

[Testing the CPU]
Use Prime 95, OCCT, Orthos or Intel Burn Tool to stress test the CPU.

[Testing the GPU]
Use Furmark or ATI Tool to stress test the GPU. If you see any artifacts, the GPU could be overheating, too overclocked, or faulty.

Oh and full specs of the PC would help.
