After she bought the laptop, she tethered her phone to it for internet. When she did that, she noticed that the computer locked up, restarted, and when it loaded back up, her desktop wallpaper was gone, the clock reverted back to 1969, and her profile was corrupted. I think she picked up a virus through her phone. The Geek Squad member that looked at her computer after that happened said the phone created a backdoor in her computer that opened it up to a virus that fried her BIOS. I am slightly skeptical about this as her BIOS still checks out to be fine.
When she let the other coworker "fix" it, he installed Vista 64-bit, and decided not to put any drivers on it, so when I got it, it was plain-jane with the 640x480 screen resolution, and it didn't work properly. It would freeze up if you left it alone for more than five minutes.
I decided to install Windows 7 Ultimate 64-bit after a low-level format of the drive. After installing Windows 7, I ran ALL of the updates, installed ALL of the drivers from Dell, and started to put on security programs. I installed Symantec Endpoint Protection 11 64-bit, Malware bytes Anti-Malware, CCleaner, and ATF-Cleaner. I have since removed ATF-Cleaner. She asked if I could install iTunes and put my music on it for her, so I said ok. After installing iTunes 64-bit, I tried to import my music from an external hard drive that runs fine in EVERY other computer. Now is where the actual problems begin.
The computer started freezing after exactly 3 minutes and 36 seconds, every time without fail. I finally booted up in Safe Mode and it didn't freeze, so I copied all of the music, and imported the music into iTunes. Upon restarting, I logged in, noticed that all of the music was gone, so I closed iTunes and ran it as an administrator. iTunes began to convert the songs, but on the third song the computer froze again. I opened the Task Manager, which usually runs fine, and to my surprise, the username column was displaying "Unknown" for every user, even SYSTEM. About 3 seconds later, the computer restarted itself, and started to freeze as soon as any program opened. As long as the mouse continued to move, the system would stay stable, but as soon as the mouse stopped moving, BAM! Everything stopped and froze. I have never encountered this problem on ANY other machine, laptop or desktop, and am in serious need of assistance. I have tested/swapped/changed the hard drive, RAM, and wireless cards, and the problem persists regardless of the hardware changes. I don't have any idea what could be causing such a persistent problem
My knowledge of Windows ranges from 3.1 all the way to 7, with very little that I do not know. My tech experience is probably about 8 out of 10. If the laptop will let me, I will post a HijackThis log tonight and anything else I can think of to be relevant. PLEASE HELP. I have already started losing hair over this problem.
