Recent built a new desktop Specs ASUS sabertooth MB AMD 4170 8GB of patriot DDR3 pc3 12800. 2 Nvidia GTS 250 SLI Windows 7 680w power supply I built this comp about a week ago and have been having program crashes ever since. I used to get the blue screen of death, but have not had that in about 4 days. The only things I have intalled on this comp is windows 7 64 bit, Steam and 3 steam games, left 4 dead2, Supreme commander 2, and Empire total war. I have origins installed which I play battlefield 3. All the games crash at some point. Sometimes they crash 3 minutes into the game and it crashes back to windows desktop, other times they crash after playing for 2 hours and then it will crash to desktop. also internet explorer 9 will stop and crash. As I was typing this I got the message that Internet explorer had stopped working and I had to retype this. Any Ideas. I have done a search, I have uninstalled and reinstalled all the games atleast 3 times, All windows updates are up to date and nothing has changed. Anyone got any ideas????
