Here’s the pream…..the pc started locking/freezing up periodically for no apparent reason. I ck’d TM and all it showed was alot of system idle usage. Then I added a wireless mouse and keyboard via USB. It started “acting stupid”,not recog. commands,etc. The next day I went to boot up and the power lights on but the drive light only blinked once. The CD/DVD spins for a short then stops. The fan runs but is noisy. Nothing on the screen. I have taken it apart and cleaned, reseated mem card, ck’d connections, and tried to clear CMOS. I am @ a loss. Please help, cannot afford to take to shop but need data.
