Hello, i've asked this question over and over but its still driving me bananas.
during many games it freezes, locks up and wont do a thing til i reboot.
and now its not updating drivers via CCC - catalyst control center - it gives a certain error saying that installation of the driver has failed in the log.
Error is.
"Driver Install: Windows® version does not support this operation"

now i am not sure what exactly is the problem. I changed my power supply to a 2b 450 .
my system specs is as following
Main board - Asus P5k
Processor - Intel Core2Duo E7300 2.66 GHZ
Rams - 2 GB Kingston ram + 2x 1 GB Kingston ram
Graphics card - Powercolor 4670 1GB PCI-E
HDD - Western Digital 320 GB and Western Digital Blue Caviar 500GB
Windows - Windows 7 Ultimate 32 bit 7600

I tested the rams via memtest, no errors. checked the processor via CPU Z .. nothing still. and changed the power supply from a generic one to the PSU i mentioned earlier.
Now to games that end up crashing.
1- The newest Medal of Honor.
2- Need For speed Hot Pursuit.
3- Batman Arkham Asylum ( its when it all started eventhough it worked perfect on XP)
4- Sniper Ghost Warrior.

Thank you in advance, and yeah i am going to change my GFX Card soon but i just need to figure out what the heck's wrong with this one until then.
