Recently, I have been having a lot of BSODs. All of which only occure during gameplay. Some games are worse than others, for example Dead Island, Flight Simulator X and Modern Warfare 3. They used to happen only to MW2 but now it seems it has become a more serious issue. The BSOD has STOP and atikmpag.sys on it. I'll try to take a picture when it does happen while I'm enjoying one of my games =.=
Are you just switching from a Nvidia card to ATI ? Or have you always used ATI cards ?
I have used this Ati card for about 1 year + and it started only with MW2 about 2 months ago. Now it seems to BSOD on other games too. I used to use an Nvidia card.
Sounds like you have left over junk from the nVidia drivers. I swear that they write them to stick and mess up ATi drivers (and vice versa! It's like gang warfare!). Likely, you didn't remove the drivers before you removed the card, and then they just magically disappeared... but they are still on your system and loaded into memory.
My recommendation would be to use the ATi removal tool (you will find it in your Control Panel under the "Programs and Features" tab) and wipe out everything from ATi, then download Drive Sweeper and have it remove everything ATi or nVidia. Then reboot, and reinstall the most recent CCC driver package.
More detailed info could be offered if you could state what motherboard and video card you are using.
It could be your video card/graphics card is failing or your drivers are messed up. Try rolling back your drivers and installing new ones. Let the website automatically detect your card so it can update it. Could always be another problem, (let's hope not).
