My PC has been Randomly crashing the past few days. Each time it has been a different cause, and each time I tried the same reason and it didnt crash the second time. First time was when I was installing an update of Flash Player, it started to load then did a quick BSOD and rebooted. After rebooting I tried to install the update and it did it normally. The same thing happened when i tried to clear my web browser history, and it crashed. When it rebooted i tried again and it did it without a problem. Any ideas?
