I have had major dramas with my PC since I bought it with it crashing regularly playing iRacing and Dirt 3. The video card would crash and sometimes recover or sometimes the whole system would crash and need a reboot.

I replaced the video card and this stopped the video card crashing but I started getting unexpected shut downs (blue screen error) randomly even when not playing games. When I recently downloaded the F1 2012 demo the video card crashed even when on low settings.

So I sent the PC back and they replaced the motherboard. Now I get it back and when I play Dirt 3 the frame rate is terrible and F1 2012 is unplayable even on the ultra low setting where as before I could play on HIGH settings and frame rate would be silky smooth but it would randomly crash for no apparent reason.

AMD Quad core 3.6ghz cpu
Radeon HD6770 gpu (original) Nvidia GTX550ti (current)
4gig Ram

Any ideas?
 
Would be useful to know the motherboard and the PSU unit.

You can download CPU-Z Click here for the link which will tell you the name of your motherboard.

With the PSU unit, what is the wattage of the unit? 800W? 500W?

I'm assuming from the slow framerate is that there is a conflict somewhere between the motherboard and the processor, as some motherboards require a bios update before it will work properly with certain processors.

Also, could we have the full name of the AMD processor? I'm guessing it is a Phenom II processor, but not the model.
 
Motherboard is Asus M5A78L-M LX PLUS
Cpu is AMD FX-4100
PSU is 550W
BIOS is American megatrends inc version 0402

How do I know which bios I need and how do I update?
 
Yea it says my current BIOS version is fine.

The only thing that has changed is the motherboard so it must be the issue. There is a newer version of BIOS which I can try.
 
What is your CPU and GPU utilization in game?
Have you tested the memory?


1- Reseat everything... GPU, ram, and ALL cables (also try different expansion slots and sata ports).
2- Driver sweep and reinstall.
3- Fresh install.

If none of the above works then it is most likely a hardware issue; unfortunately you're really going to need another mobo, gpu etc to test.
