So a couple of days ago I reformated my pc. I used to have a 32bit instalation of Windows 7 and I now installed Windows 7 ultimate 64 bit instead. Soon after blue screens started showing up and other strange things started happening. At first everything seemed fine, then suddenly Chrome wouldn't respond anymore. It didnt crash, it just didnt seem to respond to anything or load any pages. Then I got my first bluescreen. After that opening or using Chrome has been a sure way of getting a blue screen. I also sometimes get bluescreens opening windows explorer or just simply when starting the pc. The bluescreens have varied between a couple of different types. I had no problems whatsoever before remformating. I have tried uninstalling a lot of different programs and such, but it has not helped. I am at a loss on what do now. It just seems so random. Five last minidumps are attched.
