You have already indicated the following:
The old dimms don't cause a BSOD
Mixing dimms does cause a BSOD
There are a couple other things to look at but the chances are remote that they might be the issue. Three hours of the PC being turned on means that the electronics are picking up heat.
Be sure that your page/swap file is set to 6GB or larger.
Run a disk scan on the outside chance that pages being brought in are getting corrupted.
You might even try relocating the page/swap file in case it is seating on a bad disk area.
Does the PC BSOD when it is cold and you are mixing dimms?
Actually you can't really rule much out just because it somethings work in another PC. As an example, the Radeon 5xxx video card has known compatibility issues in some of the older HP PC's.

'There are a couple other things to look at but the chances are remote that they might be the issue. Three hours of the PC being turned on means that the electronics are picking up heat.'
I've been monitoring the heat tempratures for a while, and it seems to go between 40C and 50C
'Be sure that your page/swap file is set to 6GB or larger'
Its set to 13GB.
'Run a disk scan on the outside chance that pages being brought in are getting corrupted.'
'You might even try relocating the page/swap file in case it is seating on a bad disk area.'
Just done that.
'Does the PC BSOD when it is cold and you are mixing dimms?'
The desktops RAM seems to warm up on startup, then stay at a warm temprature, the RAM itself never seems to increase/decrease in temprature after startup. It just stays the same.

I just plugged the RAM into a differant desktop just to see if it had blown.
My dad said he's found 2 2GB DDR2 sticks at where he works. I'm going to try plugging those into the desktop instead, it seems that this problem is going to take a while to fix, and going to be complicated.
I'll write back if the other RAM doesn't work.
Plus, I noticed something on intergals website ( The people who made the RAM that won't work )
They are only saying that the 677MHz RAM type will work in this desktop. The RAM I'm trying to use is 800MHz.
But surely it can't be doing this due to incompatibility? There was a good 2 months of it working fine with the new RAM, then it started doing this.
(BTW, Its said

I think a different view in your "process of elimination" might be needed.
- There might be more than one failing component (as you already have found out i.e.. checksum error) and there still may be more than one faulty component.
- Not computer parts will run correctly in all computers.
- Heat will play a factor on electronic components and the electrical impedance. As components heat up, what used to work no longer works.
- New components can go faulty with age.
- When you are debugging the problem, don't assume that the component that you swap out is good or bad in the case that multiple components are faulty.
- Remove all of the possible components from the puzzle and leave them out until the issue is solved. Even at this point, you might be reinstalling a component that is faulty.
If you were to put a note on your PC describing the issue of BSOD using a mix of dimms verses just two dimms and then drop the PC off in a competent PC repair shop, the outcome might be different. If the technician could not reproduce the error, then what would that tell you? Now what are you going to do?
If the technician could reproduce the error then what do you think the technician would do based on the information that you supplied and the error that was encountered? I would think swap out all the memory and rerun the test.
The one big thing that you haven't divulged up front is all of the elimination processes that you have tried.
BTW, all of the links that I have posted are valid as I have just tested all of them.
