XP startup errors

I have a HP pavilion 533w running XP Pro, i was just on the net and not even touching the machine and windows suddenly restarted and now i get 2 errors, the first one reads: C:\windows\system32\odbcint.dll is not a valid windows image, i click OK and then i get another error that reads: The logon user interface DLL msgina.dll failed to load, i can only click a restart button and when it restarts, i get the XP startup screen and then it goes back to the first error. Ive tried the recovery disk i got but it wont load, i went to microsoft and made a 6 diskette set of reboot disks and that didnt work.(I got a fatal shutdown error). am i going to have to completely reformat my hard drive and do a new install of XP.

The first dll is indicative of a virus, the second a problem with your temp folder. Odd your recovery disk won't load, is your BIOS srt to boot from CD/DVD first

Hope you can work through it enough to get help from the Malware Removal Forum
