Strange 4870 problem

I have just recently had a strange problem arise with my system that I think is graphic related. Has occurred in both games ( e.g. COD 4 and COD 5) and regular desktop to internet surfing. The problem is that my screen, any image, will go checkerboard and lock the system up. I have updated all mobo drivers and all Vista patches are current. I am using 8.12 Catalyst drivers and have tried rolling back to 8.11 as well. Still occurs in both. I have went back to stock cpu speeds, just had a mild OC to 2.9 gHZ but temps never got hot. Never OC'd the card at all.

My specs are:

Q9300 at 2.5 gHz
4 gigs of DDR2 1066 @ 5-5-5-15
Sapphire 4870 video card
550 Antec psu
1 x 750 GB Seagate SATA HD
1 x 74 GB Raptor
Vista Business 32-bit

Everything was bought new at end of August 2008 except psu which was bought in Feb. Any ideas what may be causing this problem?

  2. Hey similar problem here on a Force3D 4870 1 Gb, with hangs occuring in Far Cry 2 and Gears of War. Specs are:
    Intel E 8400 cooled by ASUS Triton
    Gigabyte P45
    4 X 1 Gb Kingmax DDR3 1333
    Gigabyte Odin Pro PSU 800 Wt
    Force 3D 4870 1Gb
    2 X 250 Gb RAID0 WD Caviar Black
    2 X ASUS 20x DVD-RW
    Gigbyte Isolo case
    Catalyst 8.12-Vista 64
    The card is damn hot if you keep the default fan speed but the problem persists even if it's increased and the temps are normal

    Can it be a driver problem?
