I suspected some hard drive issues on my friend's computer and ran chkdsk. There was a power failure while the utility seemed stuck at 27% for all eternity, and now the computer won't produce any image on the monitor (which I have tested on other devices) or sound on the speakers (also tested) when it boots. I have since tested the old hard drive (it does have problems) and put in a new one, but the same issue remains. I also tried different SATA cables and SATA ports.
I have a slight suspicion it could be the video card, but I don't have a spare on hand. Does the computer still think it's running chkdsk? Any other things I can do on my end?
