ASUS P5GC-MX - Need help with Random Freezes

Dear Community,

The System that i have built boot perfect however will experience random freezes in windows. There's no pattern to the freezes, it will sometimes freeze within 5 mins - 20mins and if i'm lucky enough, it can last a few hours without freezing.

The freeze can occure while i'm surfing the internet, typing a word document and frequently by just leaving it idle. Dispite the remedy actions i've done the problem still exist. I'm so frustrated :fou: please advise.

Remedy Actions:
Initially i'm using a budget PSU thought it might be faulty hence I replaced it with a more stable Antec 350W PSU.
Because the motherboard only support up to DDR2 533MHZ, thought there might be some competibility issue so I replace the 667MHZ ram to 533MHZ ram
Have read some articles saying that if chasis is not grounded properly might cause stability problem hence I Change the chasis of my system to CoolerMaster 330 Elite.

I have run the following test and results are fine.
memtest86 - No Errors reported after 6 hours of testing
speedfan - Temperature check at load is nominal
Scandisk - No errors reported

I'm now suspecting that the motherbaord might be the root problem to the random freezes.

    1 Stick installed, KINGSTON 533MHZ 1GB

    The number of times the system freezes had since decreased after i replaced the 667MHZ RAM to a 533MHZ. But nevertheless i'm still cracking my head trying to stop it from freezing unexpectingly.
  4. Leave everything in BIOS for the RAM settings to default or auto.

    Thanks for the advise, I previously manually set it to 533MHZ, I have now changed it to auto. I hope this works.

    Will keep this thread posted if i encounter any freezes again.
  6. OMG! it freezes again. any advise is welcome.....i believed replacing the mobo will solve my problem. Any comments?
  7. Are you overclocking the CPU?

    What is the BIOS version on the motherboard? Is it the very latest?
  8. Are you checking CPU temps also?
  9. No, I didn't OC my CPU. It's running at default voltage.

    The BIOS is at factory settings version. Haven't done any updates to the bios. I guess will have to update the BIOS to the latest version once i'm home. will keep this post updated once i finish flashing the bios.

    CPU Temps is between 35-47 degrees.
