Whole computer crashed the other day

[simpleprincess]

My whole computer crashed on me the other day. I was playing freetime,paused it to go do something, then the monitor wouldnt come back on,then i restarted the computer and werid colours and werid rebooting happened,it did it twice,I restarted it again, left it for half and hour came back and it booted fine?. I dont know if its a freetime issue,insim issue or a general comnputer issue. im srtill getting the crashed messages but not as frequent. is it even a hard drive space issue or ram issue? im worried its a graphics card issue they are expensive to replace. :{ .

Im currently bidding on a super gaming computer on ebay with computer   specs that are off the planet!!!lol. I hope so much I win it.
