I never had this problem before, but since a week ago I get constantly BSODs with the title "IRQL-NOT-LESS-OR-EQUAL" and some hex codes while playing World of Tanks (generally I manage to play a few hours before this happens).
I updated to catalyst 13.4 in May. Then this started to happend and I Tried updating to 13.6 but it it didn't fix it.
- With 12.x drivers, sometimes my video driver crashed (while running other video-related task in the baskground as watching youtube (flash player) and playing WOT at the same time, etc. This was fixed in 13.1)
- I had to underclock my card with the AMD overdrive tool because the stock OC setup was unstable.
My card: SHAPPIRE HD 7750 1GB OC (underclocked to retail HD 7750 setup, stock OC is unstable)
CPU: AMD FX-8120 RAM: 8GB DDR3 1333
OS: Windows 7 64-bits professional
MB: ASUS M5A88-M
BIOS: M5A88-M BIOS 1601
Driver: Catalyst 13.6beta2.
PSU: Sentey BRP 700W
I also did some memtest but my ram chips were OK. No new hardware has been installed.
OS Version: 6_1_7601
Service Pack: 1_0
Thanks for your help.
