Windows 7: Radom BSOD

So I thought there was a problem with wmc, since it 1st came up then. Now my computer keeps on freezing randomly. I also thought it might be getting overheated, so I moved it in a more ventilated area, but it still has problems. I haven't really installed anything lately besides remotepotato, and I'm hoping to get it fixed to I can install my CETON infiniti4 that should arrive tomorrow. I ran a AVG and it was clean,and spybot search & destroy found some things that it fixed. Any help would be great.

Windows 7, 64 bit
It's an HP but I forget the model number.

Hi.

Uninstall ati catalyst,clean with ccleaner,restart,install the new catalyst,restat.

Wait for results and post back!

atikmdag.sys caused your latest BSOD..(ATI Radeon Kernel mode driver) Like Panais said..!!

It still freezes up, but I haven't gotten the BSOD again yet (I haven't been on to much though, and running a MSE scan right now)

Sometimes I have to manually reboot, and it get stuck "detecting storage devices..." When I was typing this it came up and said it couldn't find any (I usually reboot before it has got to that screen)

Also,
