Okay i have NO idea what this is, i have completely exhausted myself trying to fix this problem since the 3.1 have been released and now i have finally thrown up my arms in despair and hoping someone have get my butt out of the fire. Ill be browsing the internet and EVERYTHING locks up, then the screen flickers and teh aall the colors are messed up and it tells me i have a device failure. That is the most frequent problem. Now sometimes the computer wont even load up all the way, it will either freeze while trying to load up windows or it will load up windows, ill log in and then it locks up and gives me a device failure. I have no idea what to do i have tried everything, and i mean everything. Any help. Please. P.S. The file that constantly crashes is ati2dvag.dll Iv tried the 'noob' guide over at driverheavern even though i really am not a noob to hardware i was just desperate. Iv got reg cleaner and drivercleaner, and nothing is working. It is like it has just gone corrupt, i uninstalled everything, searched for the file so i could delete, but im getting nothing. Now the problems have escalated, it doesnt even boot up now, it does the windows xp with the status bar loading, then it flashes and locks up. If it does boot up, literally five minutes after just letting it sit idle on the desktop the screen will flash and i will get a device error. It happens faster if i try to do something on my computer, like browse the wb or start an application. Its like something is suddenly causing a problem, if someone could help i would really really appreicaite right about now.
