Winlogon Exe Errors When I Type In Wrong Password

When I sign on windows with the right password, it works just fine and everything loads up. However, when I happen to type out my massive password wrong the following error comes up:MCI Command Handling Window: winlogon.exe.The instruction at 0x0179116e reference memory at 0x0070ffff. The memory could not be read.I'm running XPPro. I recently reformatted my entire PC and I've never had this happen before reinstalling XP. I don't know what specifically the error stems from cause I installed so much stuff in one day. It was all the same stuff I've had on the PC before. Other accounts across the net, however, did NOT also reformat, so I'm thinking it must be something to do with a virus or some error in SP2 or windows update. I've done a virus scan and found nothing.
