xp will not boot in any mode

It started about 3 weeks ago . I thought it was a virus, one day i had
trouble after installing the demo version of CU3 Adobe package of products
for testing out illustrator. My machine became slow and unresponsive ,so i
uninstalled it and many other programs as well. I tried to run a restore and
it kept givning me the error that it could not complete the task and needed
to restart.
I thought it was a virus and tried to acess mc afee online to run a scan and
it would not alow me. So i removed all files i could remember installing
before that date, Dec 12th.I ran another scan from another virus scanner and
found some small questionable files erased them and still no big improvement.

I still could not go into safe mode no matter how i tried, i then tried the
recovery console and used the FixMBR and FIX boot , seeing if i could restore
what appears to be a corupted mbr and now it won't boot into windows at all.
It just gets to the windows logo passing the f8 selection like it wasnt there
at all and restarts all over again.MAP shows all the correct partitions and
drives.

Any ideas on what i can do?
Saside from removing the drive and installing it into this pc and running a
virus scan to see if i can repair it?

Sounds like a virus or corrupt upgrade, or both. My luck both...
