ATI 4850 blue screen crashes ingame

Ive being playing wow with this card or a few weeks now in my new pc. is been working well except the odd blue screen crash however as of a couple of days ago it wont work at all. every time i load up the game i get a blue screen crash with the error IRQL_NOT_LESS_OR_EQUAL. Also at least on time it said something about a pagable file not being pagable. This seems odd as one day its working fine and the next crashes every load. there were no game updates in between and no other downloads that i did. Tried going through all the game troubleshoot options, reinstalling etc with no result. Im running xp with sp2 and the latest calayst driver for the card. Processer driver is the latest and ive run a memory test with no problems found so im fairly sure its a graphics thing but i cant find any alternate drivers to try (omega drivers arnt compatible with this card yet). Does anyone have any suggestions or things i may have missed. Cant understand why one day it works fine and the next having this problem

Th very same thing here. I think its the driver

I'm using a 4850 as well. I'm getting 2 to 8 blue screens a day, referring to "atikmdag.sys" and the BSOD code is 0x116.
This is a very well known problem and it has been going on for about 1,5 year now, still there hasn't been found a solution for it.

Vista is telling everyone that ATi and nVidia (nvidia has another version of the prob, nvlddmkm.sys error) are the ones who should make proper drivers. While ATi and nVidia are aiming at Vista.

This also is a Vista-only problem.
