I turned on my pc just now and all seemed fine. Then I logged into my windows xp user account, it was abit sluggish. I opened MSN explorer and the screen went black and came up power saver mode. I couldn't get any response from my pc, so I had to hold the start button in until it turned off, so I could restart my pc. When it came back on, chkdsk ran and did it's stuff. Found a few errors and changed some id to a default id. Kept saying something about $130, think it was a file or something. Any guesses as to what happened?
