My computer has been randomly restarting for the last few months, but lately it's gotten much more frequent. Lately, it's once every 2 hours. I turned off auto-restart on system failure so a blue screen would show the error code. Here are the last six errors I've received (all in the last two days):



0x00000050

win32k.sys non_paged area



0x000000C2

BAD_POOL_CALLER





0x000000C2

BAD_POOL_CALLER



0x0000008e

win32k.sys



0x0000008e

ati2cqag.dll



0x0000008e



I have two sticks of RAM and I'm planning on running with just one at a time to see if a faulty stick is the problem. Any other suggestions? Thank you.
