Graphics Card Problem

Hi,
I just cleaned out my computer of all dust and when I reattached all the cables the graphics card would run really fast along with other stuff running fine, then eventually shut down. The monitor would not turn on either or rather not display anything because of the graphics card. This never happened before and was working completely fine before I started cleaning, I don't think I broke anything aside from maybe part of a fan (Long story) but I don't see how that could affect the graphics card. Some things I have tried doing to see if it fixes it:
- Changing to the other PCI Express port.
- Changing the graphics card to an older one.
- Changing the cables.
- Unplugging and replugging the power cables many times.
- Tried unplugging different fans to see if that changed it.

All of these still ended up with the same problem, it is pissing me off as I need the computer urgently for some documents.
Any help me greatly appreciated.

PS Computer Specs:
CPU: Phenom II X4 955
Motherboard: GA-MA790XT-UD4P
Graphics Card:AMD Radeon HD 6900 series

Were you properly grounded while working on the PC?

I think so... But if I wasn't no way to change that now... Could it have screwed over my computer? and is there anyway to actually fix it or get it to work?

Take a look at this video about ESD.

Do you know how to get into Device Manager, or Event Viewer?

I know how to get into event viewer and device manager but those require you to actually be able to log on... I just turn on my computer graphics card goes crazy and everything else runs fine (Inside Case), monitor shows nothing and just says "No Signal".

OK, I understand. No video. BRB changing computers.

Try removing the graphics card and see if your computer will start up using just the standard VGA adapter.

If it does, it looks like you may need to replace your graphics card.

I'll be shutting down now.

I'm sure someone else will be here soon to continue to help you.

Well I think you can rule out that option because earlier I tried an old graphics card still with the same problem and if I do remove graphics card do I need to connect the DVI cable to anywhere on the Motherboard.

In that case, you may have a motherboard problem.

How careful were you when you cleaned the system? Did you make sure you were grounded with an anti-static wrist strap first?
