Sounds like a virus or spyware. Check what services you are running, maybe even list them here. If you see any unusual ones then search for this on google.com
Ok, Ok I found the problem my TrendMicro AntiSpyware was using all my CPU! HUH?? you believe it?? omg! it never did that but then I updated it and it started using all my CPU!! I didnt look how much each application was taking up my CPU!!
Oww but now I need a good antispyware! and suggestions besides Microsoft Defender??
DevilsCharm, Yeah once that happpened to me too! I had to format my PC to bring it back, but now I made a quick research, see if this site helps ( scroll down till you find Repair, Disable or Enable the Task Manager )
What the hell, it said "Another program is using this file." As for that link, I clicked "Repair" and "Enable" task manager but I didn't understand what popped up.
Well thats a Reg file ( Registry File ) that popup asksy you if you want to add that reg key or not! but if its saying Another Program is using that file, then that would NOT arrange your problem!
I dont know!
