How sure are you that no virus is involved?
If you have scanned the harddisk with an up-to-date antivirus program,
then I think you are probably dealing with defective hardware,
possibly a problem with RAM. Here are some things to try, but I think
you will probably need help from hardware technical support.
Will the computer boot a Startup Disk? You can obtain a Windows

If the system will boot a floppy disk, you can run a RAM test. You can
download a test program from www.simmtester.com.
You put it on a
floppy disk that you boot in order to run it. It runs a cycle of
several differently patterned tests over and over.
Also, if you can boot a floppy disk, you can make backup copies of any
files you cannot afford to lose, such as financial records, address
lists, letters, spreadsheets, etc.
