My PC problems...

[RWGIII]

I'd download all the pieces from Newegg... 4 of each!

I'd have multiple computers, servers, TV's, speaker systems (got damn that'd be loud!), and everything else...

50% Processor fan (full of dust)
50% Graphics card.....
Well I had to buy a new graphics card.....
the old ones fan weht to **** if I'm right...
The new graphics card is:
EVGA  e-GeForce 8600GTS 256MB DDR3

Tomaz, I am pretty sure it is your processor fan.
Open the PC, clean out all fans with a vacuum cleaner (small one if you have) and when you switch on your PC watch if the fans are turning.
If it is broken, get one from a trashed PC.

Good luck.

You may just have poor air circulation. What processor is it? I suggest getting:

1. A better case
2. A better CPU fan
3. Some good fans for the case.

How did you download a graphics card ? 

Oops, I mean drivers

Bios - autoshutdown maybe.

If his computer is a prebuilt one he wont be able to get into the BIOS.
