I've had the same computer for 3+ years now. Roughly 2 weeks ago I reformatted the drive for the first time, and installed all of my drivers.
Last night my computer froze up while I was just web browsing. I was forced to do a manual shutdown, and when I restarted it there were all these dots on the motherboard splash screen, and then again when windows was loading. It also reset my resolution, and have been experiencing some pretty big slowdown while doing basic tasks.
I go to the device manager, and my 8800GT card has the yellow error symbol next to it. I click it and it tells me "Windows has stopped this device because it has reported problems. (Code 43)"
I've reinstalled the driver (
this one) and still no luck. Here are my system specs
-Core 2 duo @ 2.53Ghz processor
-4g ddr2 ram
-Nvidia GeForce 8800GT 512mb gpu
-I believe this
power supply
-Vista 64bit
All of my google searches tell me that if it isn't a driver problem it is probably some hardware thing. Am I boned?

The last couple of times my 5 year old computer decided to restart unexpectedly / cough up blood was mainly because of overheating issues. I am not an expert but I would suggest that you try to figure out the temperatures of your chips / HDD and see if there are any overheating components. By replacing the heatsink / fan or just by clearing out dust, you might just solve the problem with minimum cost and hassle.
I like to use Speed fan for that.
Did you make any hardware adjustments? Also, be sure to check that the drivers are correct.

I have since
-cleaned the dust out
-loaded old gpu drivers
-reformatted the harddrive
I don't think it can be driver related at this point, because even during the reformat/installing windows process the motherboard screen still had the strange blue/grey dots all over it.
Just watching it run, the fan on the gpu seems to be running fine. I am less of an expert than you are UrQuan, but it seems fine. I ran speed fan but I couldn't tell you if things are running hotter than usual. Here is a screenshot. I'm not sure why it is only showing one fan (I assume that it isn't showing the 8800's fan because it is technically not being used?):
If it helps, I could have definitely missed some other downloads. I was missing the motherboards disk, and had to download the drivers from Gigabytes website.
If you haven't messed with the hardware itself recently, then the card may just have started dying by coincidence when you reformatted.
The one, unlikely, possibility I can think of that's neither hardware nor software is that you messed with BIOS settings relating to the PCI-E slots when you reformatted, but you should know if you did that.
What you describe is a pretty common symptom of a graphics card dying.
