Windows 7: Garbled Screen - ASCII? - DURING POST

Garbled Screen - ASCII? - DURING POST

I recently attempted an install of Windows 7 onto a friends PC. The specs are listed below. Here is a link to a screenshot of the problem

This occurs after a Windows 7 install. The system boots to the Windows 7 setup, where personal options are selected. After this, a reboot will begin the POST, and prior to completion, this screen appears. I do not believe the POST has finished, and I do not think it is handing boot duties to the OS.

What I have attempted so far is:
Memtest - checked out ok.
Replaced CORSAIR mem with other sticks.
Reformat from command prompt on boot disk.
Removal of all hardware, including video card.

I am completely stumped on this issue, and any help would be appreciated.

Compaq Presario SR1110NX

Celeron 2.5 ghz

onboard sound, onboard vid (disabled in BIOS)

Can you enable onboard video and leave the dedicated card out. That looks a graphic problem.

Yes. The onboard video does the same thing. However, it is only 8mb...

Your motherboard is probably defective. Replace it.

I doubt it is the mobo. I did search for a BIOS update... However, the HP and Compaq sites that link to the file are down, and I have had zero luck from other locations.

Out of curiosity, I installed XP PRO without an issue. It does boot to XP, but XP detects both the Radeon and onboard video. I have disabled the onboard video controller, and am now attempting to do an update to 7 rather than a clean install...

Noone has any other ideas?

Discovered the issue.

Legacy USB devices evidentally caused issues with Windows 7 on this PC. I have not seen an issue in any of my other 5 boxes. After disabling legacy USB support, windows 7 boots with no issues.

However, the Radeon 9250 is not supported even though it IS listed compatible on the windows 7 compatibility site.
