I have a Epox 8k5a3+ mobo, looks like the CPU heated up, and shutdown automatically I had it set to 65 celsius. When I rebooted the next time the screen size was too big at the bottom by about an inch. So I did a restart, as XP was doing that I got the weird screen (explained later) the monitor went pure white, I hit the reset button, the pc rebooted. I no longer got the boot text, splashscreen and info, just a cahched screencap all jumbled. When XP booted, the top of the desktop starts in the middle of the monitor, and the left side of the desktop starts in the middle of the monitor. In the lower half of the monitor in the middle there is a 2 inch black and white bar with a # pattern going to the bottom of the screen, the top half of the screen is partly the desktop, and partly an old webpage and desktop that was used 2 days ago, and they're colored pink, and the desktop is different. So something cached what was on the desktop before, and it's displaying it, but in a different color, it even shows the time and date of 2 days ago in the taskbar, but that is part of the cache copy, there is also a live taskbar where the time and date are correct. Also the mouse pointer moves arround within the weird misaligned desktop. It seems to me that whatever is caching the old info is at fault for the funky display.
I put in different ram, videocard, hdd, reset cmos. Is the mobo fried?
I could get into XP fine, and open stuff, it's just impossible to do anything with a display like that. When I reset the cmos it's stuck at 7Fh screen is the same weird looking.

Your video corruption is starting when you first turn the computer on so that tells me it is probably cpu/mobo related. Probably due to the overheat/shutdown. Look at the CPU core for pitting or what may look like scorching.

CPU looks good, will swap and check results.

I tried new CPU, same deal, so it's mobo. The only thing that I know that can be written to is the BIOS, so it must have gotten overwritten?

Possible, but more than likely a component on the board is bad such as 3.3-5V-regulator or the like. Something that might affect AGP.

I have recently installed a new graphics card, there other one that was on the computer already is non removable, so i had to figure out how to disable it. I went to control panel and the display setting. Then i set the new video to the primary source, then i disabled the old one. I then connected the monitor plug to the graphics card, but the display stayed balck.

Chase, look for a setting in BIOS for display initialization and set it to PCI first or PCI/AGP. This will insure that the off board display will get first dibs on a signal before the onboard will.
