Newly purchased extreme-performance computer crashes on simple games and apps! Help!!?

Question

First of all, the system is an Alienware Area-51 7500, with a Pentium Core 2 Duo Extreme (6800E), 4 GB DDR RAM, 2X NVidia 7900GTX GPU's, 2 Western Digital Raptor hard drives, 10,000 RPM, in a RAID-0 configuration (Data Striping). Games seem to crash out regularly, although they'll run for 5 minutes up to an hour FLAWLESSLY, with details maxed, pushing over 100 frames per second... Then will randomly crash, regardless of detail levels, sound configs, anything! The system does NOT go in the BSOD mode, and can start anything right back up, but it just seems odd that games would react so badly to such a powerful system. Source Engine games (specific examples: Halflife 2, Counterstrike: Source) seem to crash the fastest, and are the only ones that leave a specific error msg, "0x### (memory address) tried to execute a command on 0x### (another memory address) and the address could not be read" Or something to that effect, it's listed on Valve's website, tried all fixes, no luck. Ideas?

Tried all of the above, and have done a variety of Valve support mentioned fixes... No effect, they run wonderfully, and crash at random intervals

Answer 1

Firstly this seems like it maybe a hardware issue. A few things you can test are run in non-sli mode with one card or run on 2GBs of DDR RAM. Plus are you playing in windowed mode, this can cause problems.

You may need to update drivers as well.

The other things is that You should ask Alienware tech about this.

Answer 2

Reinstalling the games? Did you try restarting your computer. My games have done funky stuff like that, and a simple restart and everything will be fine. Or leaving my computer alone and trying it again in 10 minutes it will work. I would try reinstalling it though for a last option, maybe something messed up when installing it. I get those memory address's thing from time to time and they go away about 10-15 minutes later, I've never known what has caused them.
