I'm not sure I understand the discription, do you mean the loading
progress bar?
What is the background, the XP splash screen?

"Get to the internet to do a virus scan"? This implies you may not have
anti-virus software installed but rely on free online scanners?
If that is the case your PC is probably crippled - format reinstall only
option,
and install a full AV application too, but first....
Try and explain exactly what is happening
When you say you "tried to repair", how? from an XP installation disk,
pre-installed recovery console, What exactly are you doing?
What "typed search" were you doing - explain.

Obvious stuff now, you are the administrator, are there other users logons?
Are you, or were you receiving error messages - "Invalid Boot.ini" or
"system32/Hal.dll", error codes or registry errors -hive etc.
If any error messages, be precise
Are there any disks in DVD/CD drives - remove them
disconnect externally connected hardware
Have you looked inside the tower and tried reseating RAM sticks,
or removing one RAM module, try booting, then alternate with other.
