Well here is the deal. I have a laptop that came into my shop last week, an HP G62 with Windows 7 Home Premium 64-bit. The user needed immediate file recovery which was done without a problem, and then I went to town on fixing the issue.
The customer reported a "memory error" popping up before they shut the computer down. Upon restart, Windows would only load to a black screen with the mouse cursor. I've encountered this in the past and through various methods, such as CTRL+ALT+DEL or Startup Repair, but this one has eluded me for some time.
No matter what I do, I can not get anything to launch on this computer. Windows from the hard drive, Windows from the install CD, built in Startup Repair, and Windows in every single startup mode all returns a black screen with the cursor. No shortcut keys seem to do anything.
I have also connected it to an external monitor to see if that was an issue, and it wasn't. I have tried UBCD to no avail, it just doesn't start. I have tried BartPE with a Window XP Pro install and received a blue screen.
I have connected the hard drive as an external and run virus and malware scans with no issues found. I have tried to run CHKDSK, but the drive hangs about halfway through. The files, however, are all accessible and able to be moved/removed, but it does not allow me to change permissions. I have heard about this being a permission error, but I have had no luck in that department.
The cd-rom drive works as I have just tried Paragon Partition Manager to use the boot corrector, however, it seems to be to no avail either.
MemTest turned up no errors. Just to be sure I ran it with each memory stick going solo, same results.
I am at a loss for what to do or what the error could be that has caused this suddenly. Any further ideas will help greatly.
