Computer Randomly Freezes/Locks Up

[animestan]

Hello, i've been having a re-occuring problem with my pc. This error has only occured during gaming. Visual indication would be the screen freezing on a specific frame. Sound would indiciate a reptition/loop of the last half second of noise produced by the game. And for my pc case, i have a LED that connects to the HDD that blinks to show HDD activity. When the freezing first starts, it would blink in a constant cycle, then a few moments later, the light would turn off, My screen would still be frozen, and the sound would not loop anymore, but only play the last sound genereated by the game.

Things I've done to try to troubleshoot;
1. Chckdsk (Using regular chkdsk in run will check to about 2nd or 3rd step, then it says errors found cannot run in read only mode.
2. chkdsk /f
3. Ran SEAGATE diag tools. Tests run: SMART check, Short drive self test, short generic test. All tests came back as PASSED
4. Right click My Pc -> Manage -> Disk Management -> Right-Click C drive -> Properties -> Error Checking -> Check Now. The test would not start till i rebooted (and i did so) I waited for the 5 step test to finish, and my regular boot up screen proceeded and i logged in.
*I've updated graphic card drivers and HDD firmware
5. Gone out and bought MX-2 thermal paste and reapplied it to my CPU (assume the heatsink and paste is properly applied)
6. Cleaned out all dust from PC
PC SPECS:
Quad core Q9450
Seagate 500gb
bfg gts250
kingston 4gb ram
coolmaster 600W
Win Xp Sp2


*I've tried to check for errors in event viewer, but nothing poitns to a freeze or shutdown
I've asked other ppl bout my temps, but they said the temps were fine.

if your computer require ram pairs pull two if not pull one stick and see if you still have the problem.

I"ve just finished a Memtest86 + v4.00 My ram passed the test.
Any other ideas?

Update: I decided that the next time it freezes up, I'll wait for a while...
Today, when it freezed (During TF2) I decided to just sit there. A while later I saw the LED light for my HDD blink and the sound came back for a split second then my pc restarted. Also , I additionally ran the Seagate Long Self Drive test
Any ideas?

Update 2:
So basically after the restart of my pc I started doing what I regularly do. After I was done, I shut it down.

Next morning, I turn on my pc, boot up and everything was fine, but I recieved an additional dialog box saying my pc has recovered from a serious error (dont know why it came up, and if it should come up, shouldnt it have come up after the auto restart ?)
Heres the log in event viewer.
