Problems with video distortion after duster cleanup

[includepr]

My PC was working fine and then I cleaned the entire PC with air-dusters. I cleaned it with short bursts of the air-duster and did not tilt it sideways. When I assembled back the PC without removing the processor, the monitor display's the normal BIOS screen but with video being distorted. Like a bunch of discoloration on the screen. I tested the monitor in another computer and it's not the monitor. Please Help

Here is what I have done so far:

1- Replaced the memory to another one that I had.
2-Tried another graphics card. ("thought this was it")
3-Tried another PSU.
4-Tried to clean any excess dust.
5-Cleared CMOS/ram
6-Tried another computer on the same monitor

And the problem persists. If you want to see pictures of the display click below.

Two possiblities with no guarantee that either will work:

1. I've seen weird video when a machine is misreading a hard drive. Try unplugging and reseating the cables from your motherboard to your drives.

For IDE drives, for reasons I have yet to understand, I've found that running your finger along the IDE connector pins of the drive sometimes resets whatever was causing the problem.

2. If that doesn't help, try re-flashing your BIOS. Again, I don't know, but if it became corrupted, re-flashing it may restore it to working shape.

I hope others have more suggestions. Good luck.

Damaged PCIe (or AGP, or whatever) slot? You tried everything else except swapping out the motherboard, it sounds like.

Thanks for the responses. I will try messing around with the IDE cables and drive.

I still have this problem. I think it has to be the CPU. Because I changed the Video Card and also because you can see in the pictures the Bios screen has gibberish between normal characters. Thanks for the help.

well, what's left? booting without a hdd and dvd drive connected, check the graphics cards slot to see if there's any physical damage, try another CPU and finally try another motherboard
