My friend's laptop has been receiving BSOD very frequently at random intervals. As he's studying software programming as well, the BSOD happens mostly when he hits the F5 button to debug his programs. It even happens when he's just browsing the web. Please help.

These were all caused by the iastor.sys file (your storage driver) A simple re-install should help the problem
