the computer i have is custom built, its been working fine and recently i upgraded my mobo, ram, and cpu

mobo is lanPartyDK 790FX series

ram is 2 gigs of g.skill ddr2 800

cpu is an amd athlon 64 x2 dual-core processor

ive been troubleshooting for a few days but nothing has worked so far, my guess is that the hardware is either uncompatable or i need to reformat. Please help

STOP 0x0000007B means Windows cannot access the boot device. Because moved an existing Windows installation onto a different motherboard, the most likely culprits are a storage-controller mismatch (IDE vs AHCI/RAID), missing storage drivers, or a corrupted boot record. The original post does not specify the Windows version, so the steps below give both generic checks and OS-specific recovery commands.

Quick checklist (do these first): confirm the drive is detected in BIOS/UEFI; check SATA/power cables and try a different SATA port; check the BIOS SATA mode and, if it’s set to AHCI/RAID, temporarily switch to IDE/Compatibility to see if the system will boot (record original settings first). If BIOS shows no disk at all, fix cabling/power before attempting OS repairs. Resetting CMOS can help if settings are inconsistent.

If the disk is detected but Windows still fails, use the recovery tools for your OS. For Windows 7/Vista boot the install media to the Recovery Environment -> Command Prompt and run:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
chkdsk C: /f /r

For Windows XP use the Recovery Console and run:

fixboot
fixmbr
chkdsk /p /r

If the problem is missing AHCI/RAID drivers, the usual workaround is: set BIOS to IDE/Compatibility, boot into Windows, install the correct chipset/storage drivers for the new motherboard, then (if desired) enable AHCI in Windows and switch BIOS back. XP typically requires loading SATA drivers during setup (F6) or a repair install; Vista/7 generally detect and install drivers more easily.

Always back up important data before attempting fixes: boot a Linux live USB or attach the drive to another PC to copy files. If recovery and driver fixes fail, a repair install (non-destructive) is the next step; if that too fails, a clean install after backing up data is the most reliable solution.
