I have a client with a PC that I can't get to boot Windows. If left alone, the PC gets stuck in a reboot loop. The screen stays blank but the num lock light goes on/off every few seconds. If the disk tray is open, it shuts after the num lock key flashes. If I mash the F8 key nothing happens. Heres what I've tried:
Put the drive in another computer as a slave and run a full Malwarebytes & Vipre Antivirus Scan. Both came back clean.
Boot the PC with the Kaspersky Rescue Disk and run a full scan. Came back clean.
Run a full CHKDSK /F while the drive is in another machine as a slave. No problems were found. No problems or delays in browsing the file-structure either, while it was a slave drive.
I used a Paragon backup and recovery 12 home CD to fix partition boot records and the MBR.
Ran a SFC /SCANNOW /OFFBOOTDIR /OFFWINDIR while it was a slave drive in another PC. Came back ok.
I really don't know what to do at this point. The drive seems to be in good condition and virus free but it still does not come up. The last thing on my list is to burn a system repair disc in my version of windows 7 and boot up the customers machine with it, in hopes that that will provide me with a system restore option.
