Windows 7: Black screen blinking line please help

Windows 7 Ultimate 32bit
Black screen blinking line please help

Ok I am at my wits end with this computer. I am trying to do a clean install of Windows 7 from a thumb drive, I have used this thumb drive for several successful installs, including one after my issue just to make sure it wasn't corrupt.

PC details Foxconn A74ML-k Motherboard with a Dual Core Amd proccessor, sorry cant find the model off hand. using on board graphics card, and a Western Digital WD6401AALS hard drive and 2 gigs of gskill ram.

This PC was running windows vista just fine before I attempted to Install Windows 7, I have tried to install Windows twice, once with the usb drive and once with a dvd disc both end results are the same. The install will go perfectly smooth, all the way til the final reboot. Once the actual install is complete when it try to first boot all I get is a black screen with a blinking cursor, I cant seem to enter safe mode.

I have searched and while it seems many have run into similar issues is usually due to things such as dual monitor set ups etc. All I have connected is a mouse, monitor, and keyboard. Microsoft lists the motherboard as compatible, I have reset the bios, tried a different hard drive, ubuntu live works just fine, the file system is there. I even pulled the hard drive out of my laptop and plugged it into the pc and I get the same result. Also I tried windows start up repair from the discs, it found no issues.

So please, any help, ideas, suggestions, Anything would be much appreciated

Try rebooting into Safe Mode to uninstall any drivers in error in Device Manager.

If it will not boot into Safe Mode, use the steps given in this tutorial to enter the Device Manager using Command Line to find the problem driver (likely display) and uninstall it to force installation to complete. Device Manager - Access During Windows 7 Installation

Have you wiped the HD to try install, as you may have corrupt boot code? SSD / HDD : Optimize for Windows Reinstallation

Remove all but 2gb of RAM to try install, test your RAM, swap your RAM: RAM - Test with Memtest86+

Do you have the latest BIOS update? If so, reset the CMOS: Clear CMOS - 3 Ways To Clear the CMOS - Reset BIOS

While in BIOS, set SATA controller to AHCI to try install, then IDE if it fails.

If you have had Grub on that HDD I would suggest, after you have copied out or made back-ups of the data you need to save to external media, use Step One of this tutorial at the link below to do a wipe (secure erase) to the entire Hard Disk Drive, running this "clean all" then using the outline in Step Two #2 to create/format and mark Active a single 100GB partition using diskpart will get you the best possible space to do a clean install of Windows 7 to; you can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional partitions after the installation completes if you choose.
