Hi All,
I just joined Tom's, but I've used the site for a while. The reason I just now joined is because I'm having a problem, and yes, I have searched far and wide for the reason, but have never really gotten a good answer.
The problem only really occurs whilst playing games, but it doesn't really apply to all of them.
I got System Shock 2 to run on my system, and It never freezes. It seems to only happen on more modern games.
I read some article somewhere that said It could be UAC, so I disabled UAC and Defender (only because I have Avast running, and 2 anti viruses are doing me no good).
Like I said, it's basically a completely random full system freeze when playing modern games. No Ctrl-Alt-Del, no Alt-Tab, the only thing that fixes it is a system reboot.

My system is as follows:

Windows 7 64bit
Gigabyte GA-890GPA-UD3H
AMD Phenom II x4 965 Processor
Bios is stock
6 GB Ram (I have 1 stick of OCZ Platinum PC3 10666 7-7-7 @ 1.65v, and 2 sticks of Crucial 2 GB sticks overclocked to run at 7-7-7 with a couple notches into power)
2 ATi HIS 5750's Crossfire'd

Would appreciate any insight.

It's usually a RAM issue of some sort. With that odd RAM config I'd toss the OCZ and see if it works then. (and/or relax timings, etc)

Have you monitored your temps? It may also be a CPU or GPU overheating problem. Modern games are more demanding than older games.

Its not a temperature problem, I have 2 case fans, and a huge heat sink/fan combo on the CPU. I tried the RAM, seems to have been a temporary fix, the freezes still happen, just not so often.

You tried pulling it out?

Or adjusting the timings to normal or less?

If you only pulled out the OCZ I'd try the other as well.
