awlful somehow my system retsore got turned off so I couldn't go back. My logitech headset won't work, my dvd roms don't read any disks also I can't do a defrag on my system . also I can't play cod4 or modernwarfare2 it lets me in a game then it crashes and reboots my system...;( I don't know what I can do. I feel all I can do is reformat but my drive can't even read the disk when I put it in it seems to want to but I can hear it zooming up but it doesn't do any thing. What's weird is I can burn a disk.
