My computer recently crashed with weird multicoloured horizontal lines, forcing me to restart. Since then it's been crashing with the BSOD in the title after around 5-10 minutes. I've cleaned the inside with air and checked for malware/viruses with no change in the situation. Any help with this would be most appreciated! I've had that BSOD before but not for a couple of months, at least. This happened when I was playing Diablo III but recurs with only my web browser open.
