Windows 7: Random PC Freezes revisited

10 Apr 2012   #1

Windows 7 64-bit
Random PC Freezes revisited


As the thread title suggests, My PC freezes (semi-)randomly.
Actually, I would like to refer to a previous thread with the same title as I believe it might be the exact same issue.

OK, first off some of my specs and situation overview, if I forget something, you'll be sure to point me out.

- I ran Vista 64bit and reinstalled my C: partition some months ago with Windows 7 Home Premium edition 64-bit.
- I have a Intel Core2 Q6600 2.4Ghz CPU
- On an ASUS PK5 motherboard
- With 4x 1GB Corsair DDR2 (PC2-6400) memory
- And an NVidia GeForce 8800GT graphics card

Now ever since the install of Windows 7 I get these random crashes, even when no extra software or games were installed.

I said in the beginning that the crashes were semi-random, as they do happen sometimes with no explanation at all.
But for example when I run Heroes of Migh and Magic 6, after about 5 minutes, the PC freezes. But it's not related to the game, as it happens at a different moment each time and has the same symptoms as the random freezes which occur sometimes not, sometimes once or twice a day.

The symptoms of a freeze are almost always the same:
- Everything freezes up obviously
- The screen gets scrambled with trembling pixels (you know, the little horizontal stripes in magenta color kinda)
- And the sound hangs too giving an annoying hanging record-sound.
-The only solution is pushing the reset button.

Now, what have I already tried (with no succes):
- Updated Graphics card drivers to the latest
- Tried playing with the power saving options

Before I actualy take on the Bios (which is now version 0603 and the latest is 1201) and change the voltage or timings parameters on my memory, I would like you guys to give me your professional feedback...

Asus P5K mobo's aren't certified compatible with Windows 7. We can work on this with you, but there are no guarantees.

FWIW - I've seen a lot of issues with the Asus P5 series of boards. I usually recommend this:
- DO NOT use the AUTO setting for memory. Go to the RAM manufacturer's website ( Corsair ) and get the recommended settings for the RAM. Then set those settings manually in the BIOS
- one person with a 2009 BIOS has experienced success by updating the BIOS. This is dangerous and one simple mistake can easily damage your motherboard so it won't work. Be VERY, VERY CAREFUL!!!
- one person reports bad caps ( - How To Identify ) in this post: [SOLVED] Bad overclock and now can't load windows 7 - Tech Support Forum
Then please provide this info even though you're not reporting BSOD's:
