BSOD at random times...ntoskrnl.exe

Ok, I let my friend just use her computer for a while and now she brought it back and she said the computer just went to a black screen and now it wont boot up and the same thing is wrong the hard drive isn't recognized by the bios. the first time it happened i moved the hard drive to a different cable(the one for the cd drive) and it was recognized that way so i moved it back to its original cable and it worked fine then. So could it possibly be the motherboard or are you placing your bets on the hard drive? Thanks in advance!

Let's just confirm nothing is wrong with the hard-drive:

Run some hard-drive diagnostics and follow these steps:

• Hard Drive Diagnostic Procedure

Find your hard-drive manufacturer and run their tests.

Additional Tests:

• SeaTools for DOS | Seagate
• CrystalDiskInfo - Software - Crystal Dew World

If you have an SSD, make sure the following are up to date:

• SSD firmware
• BIOS Version
• Chipset Drivers
• Hard disk controller drivers/SATA drivers
• If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

Check for any file system errors and bad sectors using Option #2 of:

• Disk Check

Use this command with Disk Check:

Code:

chkdsk C: /f /r

Thanks for all your help Blue Robot! I put a different hard drive in the computer and it booted without a problem, but this hard drive still won't boot so I'm gonna order another hard drive. Thanks again!:)
