Hey guys,

Problem when gaming. After 15-20 mins into a game the PC freezes with sounds stuck in a loop. Especially so with COD4-MW, it can only run for @ most 10 mins then PC crashes with weird pixelation on screen.

Although I know most will suggest that GPU heating is the problem, but I had cleaned it up about couple of months ago & since then till now it stays within limits (60-90 ). Earlier it was 70-108. More so it being an OC edition card.

So I down clocked core/shader/mem from 650/1800/950 (MSI OC ed stock) to 600/1500/900 (8800 stock) & rest CPU/mem/FSB back to stock still its the same hang problem No gaming for now on 8800

Mem sticks are fine, tested with memtest. Even tested with 1 stick @ a time. Funnily enough prime95 runs 2-3 hrs fine without any problem.

Can ne1 suggest something else to look into? BTW theres only a regular heatsink on the MB NB which gets very hot whilst gaming/freeze & its got a sticker on it that says warranty void if removed, so cant use my HR05 sli cooler on it. Does DFI really void warranty if I replace cooler??

Could that be the problem extra PCIE 2.0 bandwidth going through NB & it gets hot & freezes. Just a theory if sounding like a noob

Will try & put in a spare 8400gs in it & test gaming. & also check 8800 on my old XFX 650i & Asus 7050 boards.

Meanwhile all suggestions welcome.. Thanks
