My computer has been acting crazy and I am trying to reload the operating system using the disk that came with the computer. For some reason when you cut the computer off with the disk in the drive and restart the computer it wont run the disk (never had any problems running any other disk). Its almost like the virus will not let it reboot my hard drive. When I restart my computer this pops up <RUNDLL> error loading "c:\windows\system32\sjigaxy.dll" specific module cant be found. When I have been using my computer for a while it will get to where it just wont let you click on anything like it freezes up but you can still move the mouse around!!!!!!!! I have ran 2 diff virus scans with multiple other scans and they all come up clean??? Anyways anybody know how I can reboot my system using the disk that came with it??????
