My computer will shut itself off when im using it. what it does is the monitor and sound from speakers cut off and its unresponsive to anything but turning it off manually it doesnt EVEN make that ugly beep when youre holding down the buttons on the keyboard and the computer is frozen. the monitor light and cpu light and fan are all still on and going. i dont know what causes it. any ideas?That would be a complete System lockup

It could be caused by allot of things, i suggest you post a "hijack this" log right here and then we might be able to see what the problem is

Just run that program and post the log up herePerhaps posting details of your system, operating system, what happened prior to this, spyware/virus protection would help us determine the problem.Operating System System Model

i was afraid to post my virus protection but at the Belarc website it said it was up to date. i think it may have something to do with this virus i got it was the msblast.exe i dunno if i removed it right.Check for overheating: Does the case feel warm to the touch? Is there a lot of dust buildup on the cooling vents? Has the power supply fan, or other fans, stopped spinning?

it hasnt done it in a long time so i dont know if its hot to the touch but the fans sound like theyre on the same way they are when the computer is on normally. just seems like something is cutting out video and sound feed or something.do you think that it might be invoked by anything, because my computer will randomly halt like that when I do anything graphical, like play a game or somthing. I think it might be a windows issue, bu I'm not sure yet.i dunno, i havent really noticed a pattern, it used to seem like it was something connected to how many characters i typed. for instance i could be online chatting for like 2 hours and it would do it. another time my cousins and i were writing a play for fun on word pad and it did it 15 MINUTES after we started typing. but then one time it did it when i was playing the sims and had hardly typed anything. i dont think it could have anything to do with my sound card because that would mean the sound would go out and not the visuals on the screen. when it turns off like that my screen still looks like its on but nothing is displayed its just all black but whatever light source is still there because i can turn off my light and the screen will glow unless i adjust the contrast all the way down.
