Windows 7 64bit crashes everytime I try to run Windows 7 Phone emulator

I have Vs 2010, Vs 2012, Windows phone 7.1 & 7.8 SDK on my computer and everytime I make a default project in Vs 2010 and try to run the emulator my computer crashes.

This was the last error.

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: win32k.sys



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

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer

This is usually a hardware problem with the CPU. Make sure the CPU isn't overheating. Make sure the BIOS supports the CPU. Upgrading the BIOS may help. It could be a motherboard chipset driver. You can try installing the latest drivers for your chipset.

Microsoft says malware or a failing hard drive could cause this error. So I'd check for that just to be on the safe side. I'd also boot from a memtest86+ CD and let it run for a few hours to rule out some more hardware issues.
