Comp Prob. Happened out of Blue... MOBO? COOLING?
Okay guys, I need some input computer used to run great until I screwed something up. Well at least I don't know if it was me or not. I put in a new 512mb pc2700 ram whether this has to do with it or not I don't know. Anyway, computer used to run fine run great, Now is I like watcha dvd for like 5 min, or start to play a game. Not even 30 seconds my comp will just freeze. Like lock up, unrecoverable only to get it off is hard shut down then turn back on but same thing happens. I can't do anything. And I used to run WoW and Doom3 and HL2 and Guild and FarCry easily no prob @ all. And now it just stopped I don't know if this has to do with a HD MOBO or Cooling or what or what i've reformmated 3 times and checked all my connections inside and out everything is good. Any suggestions?
