I recently Upgraded my computer with a quad core and what not... specs... because i know ppl will ask...

Asus M3A78 - Mobo
AMD Phenom 9600 Black edition - Proc.
Sapphire ATI Radeon HD 4850 - VC
4 GB G Skill - RAM
100GB Western Digital - HDD

I am running Windows XP Pro SP2

Annnyways lets get to the issue... I just hooked up all the new parts ( the mobo/proc./vc/ram) And it all works out okay (downloaded and installed latest ATI drivers)... until i try entering a game(Call of Duty 4) it went through watever auto config it does after detecting new Hardware... So it starts okay, although im using a 1680x1050 compatible LCD monitor so i up the resolution for a nice picture... goes through usual things and ten it freezes resets to a horribly low resolution and messy color range stating "ati2dvag display driver has encountered an error... restart your computer blah blah..." So I do... try again and same error... It seemed to run fine before i changed resolution... NOTE: this isnt even in game jsut the menu....

So after i get this i decide to reinstall teh drivers...I go through... first boot after drivers are reinstalled i get a blue screen error stating ati2dvag had encountered an infinite loop error.... 0x000000EA ( might be 1 more or less 0's there) look it up to fin its simply an infinite loop error...

So i restarted it and seems to run okay... havent gotten an error again... havent tried running a game didnt think to... I'll report back on if anything else works

UPDATE: SAME problem.... my desktop runs at 1680x1050... game runs at the low resolution but i cant stand playing at that resolution... Not over clocking at all.... Maybe installing DirectX again?? cause i got a "Direct X has encountered an error it can not escape from" I have a feeling that error is caused by the ati2dvag not the other way around... help plz!!

I did not do a fresh install of windows... i would like to avoid reformatting the hard drive if at all possible...

Just a quick question... my HD 4850 is considered the 4800 series right?? if not i'm downloading the wrong drivers... although i thought ati would catch if it wasnt the right driver... tried googling it but nothing came up that was useful

Thanks for any help in advance

empty your DRM. I was having troubles after going quad, DRM fixed it.

have hidden files diabled, go C program data, microsoft, empty DRM folder.

not seeing a "microsoft" in program data folder... there is an "Electronic Arts" thats all...

yes i can see hidden folders

just a note this error occurs with other games also... not just Cod4

power supply
brand
wattage

try the driver install again

in the device manager uninstall the video card
reboot tapping f8 and choose vga mode
when windows finishes rebooting
disable a/virus
install your drivers
reboot the computer

power suppply is ... winsis 350 watt...
but i figured since everyting ran okay that wouldnt be the issue... im on the computer right now

I'll try the VGAmode thing and report back

Frozenprok

WOW!! it worked thanks alot dai!! ( and magnethead for the attempt :P )

Anyone mind explaining what vga mode did to make it work like that??
i'm prolly gonna do research of my own... but a short explination would be lovely :D feel free to not define terms cause i have google and i know how to use it

Thanks again guys... i think i'll be coming back here for help and see if i cant help others ;)

vga loads the generic driver so you see a screen and can see what you are doing
but it stops windows from loading it's version of the driver
if you have 2 versions loaded it can cause a conflict between them
glad you have it sorted
