BSOD (Blue Screen Of Death)

I bought a computer at the start of this year and ive been getting a blue screen saying

"A problem has been detected and windows has been shut down to prevent damage to your computer.

The problem seems to be caused by the following file: ati2dvag

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

The device driver got stuck in an infinite loop. This usually indicates problem with the device itself or with the device driver programming the hardware incorrectly.

Please check with your hardware device vendor for any driver updates.

Technical information:

***STOP: 0x000000EA (0x864CF440,0x83DB3708,0xF7A07CB4,0x00000001)

Its not the first time ive got this blue screen its been atleast over 20 times. It mainly happens when im playing a game and watching a movie or when im doing alot of stuff on the computer at once.

If any one noes anything about this error please help.

 

it's possible that your memory has a problem. trying replacing it to see if it would work

 

I have 2 512 ddr ram sticks is there any way of knowing which one is the bad one

 

try this,

http://www.memtest86.com/

 

Could it also be an ATI Driver prob...I think I had the same error(Maybe a little different) and reinstalled my ATI drviers

 

thats what i think, incompatibilaty problem

 

ive already reinstalled my drivers many times so it cant be that. ive also done that memtest but how long does it approx take? and how do you just make it search the ram

 

you never know, you might have a Virus, are you using "protection"..

 

Its not a virus i got norton and ive formated my computer many times and still the same. Could it be my graphic card or something. How do i find out

 

Does any one no any good hardware testers so i can test if anything is wrong with them
