Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error.
I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it.
I have a Dell laptop running Vista Home Basic SP2.
If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first.
