Hi!
Today i installed latest K-Lite codec pack. And right after that a few weird green boxes appeared on screen and the pc freezed. I thought this is related to my video card because i use very old driver and thought there must be some compatiblity isue between the driver and k-lite. So i downloaded the latest radeon drivers and installed them. Right after this my pc freezed again. After restart the freezes became small halts. Meaning sometimes the weirt boxes/lines appeared my screen turned black and after a few seconds i got a message my display drivers stopped working but recovered. I got back the control but after this it appeared every 30-40 seconds and after the 5th or 6th time the pc freezed completly. So i had very little time but i managed to check out some things. My new video drivers set my card cpu and mem freq to very low numbers. I read somewhere this could be the problem, so i tried out this registry fix of course it did not but of worked. After this i tried out rolling back drivers, reinstalling them, using the microsoft native drivers but none of them worked. Tried out the profile fix id didnt work neither. By this time it wasnt only appearing in windows. After the restart even the boot logo and bios screen was messed up. Tried everything. So i thought its time to reflash my vbios. Did a usb bootable stick and flashed the bios. This didnt help so i searched on the net for an earlier bios and flashed it too. Same problem. I though maybe i couldnt properly flash the bios so i put the card into another pc but the screeen was so messed up i coudnt even start windows.
The card is: SAPPHIRE Radeon 4850 Toxic
Worked with this sh*t the whole day. Please help dont know what to do next.
