Pc sos

[Law]

Hey Guys,

I have managed to break my pc in a new and wonderful way and was wondering if anyone could give me some pointers as to what the problem might be, I'll list symptoms and cause and what my friends think it is!

Primary Symptom: The pc boots up no prob but when it does the sound is way off, stuttering would be the best description and the clock loses time. Video's cannot be played, though I have not tried a CD from the DVD drive, I doubt it'll work. Screens open and close as though laggy, there are always system resources available according to Task Manager.

Secondary Symptom: Something interesting that I noticed is when I was playing Demigod I was using both EVGA precision and GPU-Z, my FPS were >50, yet I could see the graphical lag and the sound was corrupting (this particular time it started ok and got worse over a 15 minute period).

Cause: I downloaded Darkfall to try and after playing for about 2 minutes the game (not the pc) crashes out with a msg about the clocks not syncing, and low and behold I notice that my clock is wrong (did not realize it was loosing time then) as well as my sound being funky.

What my friends think: They reckon it has changed some BIOS settings somehow, or done something to the gfx card, though I uninstalled and re-installed the gfx drivers, I also updated the sound drivers to the Creative Audigy SE 2009 drivers which are the newest I can find. Could a BIOS problem be stopping it from all working in sync?

This problem doesn't present itself on every boot up, just the majority.

Thanks in advance,

Law.
