I turned my computer on, started CS:GO, then it froze. Whatever, turn it off turned it back on asked me to put in my windows 7 disc and reboot. I put in the disc and booted then I restarted and started windows normally. Everything was fine after that then about 20-30 minutes later a blue screen came up and told me to reboot my computer if this is the first time this has happened(it is) rebooted put in windows 7 disc restarted windows normally. Now this time I'm very worried so now my computer is up and running but I went to play a game and I was very laggy, I noticed my ping was 150 so I assumed that was the problem. I played an offline game and it was still very laggy. Then I tried a different game that was demanding at all (Unturned) little bit of lag, played for 5 minutes froze again. I got a message saying "display driver has stopped responding and has recovered". Now I'm sitting here with this message on my screen wondering what I should do? I've been putting of a windows update but could that cause all of this to happen? Is my mobo shorted? My RAM faulty? Should I shut off my computer? Please help!
