It sounds like a generally unstable computer now. It could be your Windows install was corrupted in the power outage, or (less likely) hardware damaged. Are you using NTFS or FAT32? I believe NTFS is much more resilient to improper shutdowns (something i've noticed personally, damn people tripping over power cables at LAN parties
). You should probably try Scandisk and Defrag to see if that solves any disk problems. If not, reformat and start anew...
