So the other day i opened up my gf computer and cleaned out the dust with compressed air and did a reformat and put a radeon x1950 pro in it. Well now it seems after a couple hours it just shuts off randomly. I could be watching a video or playing a game and boom off.
So facepunch what could be wrong? I dont think its over heating, maybe its the video card.
PSU could be overloading and shutting down from thermal events. How many watts is the PSU?
I think its a 460 watt but ill let ya know for sure
You don't get a BSOD?
When I first bought an Asus GTX570 that requires around 600W and +12A at the time I had a PSU with barely 300W, naturally what happened is whenever I started a game it would just shut off my computer without warning like you describe OP.
Then I bought a new PSU on 850W to make up for the graphics card, ever since then I haven't had a single shutdown problem like that.
tl;dr it might be that whatever graphics card or any other component in the computer really, uses up enough Watts combined so the PSU can't handle it. So from the sound of 400W that's really not much if you have alot of "modern" components in your computer, from my experience
If 400W was enough for the computer to run fine before and the new Radeon GPU is what made the problems start, just connect two and two and see how many Watts your GPU needs to run and compensate for that in a new PSU. Plus when I bought a new PSU I put in a few extra Watts aswell incase I ever wanted to add another harddrive or something like that, also something to think of I guess

460W should be fine for an old x1950, unless its a really shitty brand.
Get HW monitor and check if annything is overheating.
A x1950 has one 75W PCIe power connector, and can pull 75W from the motherboard, for a grand total of 150W (the x1950 will never pull that much.) I suspect you have a shitty PSU brand, or your PSU is just old and worn out. You should be fine with a 500-600W PSU if you buy a new one.
Its a good PSU its a cooler master. I put a Geforce GT duel dvi 520 to see if that would fix it and it just turned off. Hm maybe i should get a 500 watt.
Heres a picture of the temps from HWmonitor

Not all Cooler Master PSUs are what I would call "great". Their lower end PSUs are pretty awful, but the more expensive models are generally decent.
Your +12v rail is out of ATX spec, which could be why the PSU is shutting off. The ATX spec allows +/-5% spread on all positive power rails, and +/-10% on all negative power rails. The lowest it should be allowed to go is 11.6v, but you're sitting at 11.1v, which is way off.
Since voltage readings through the SMBus monitoring chip are usually way off, I would grab a volt meter and measure the +12v rail directly to see if the values match up. Just grab a molex connector off the PSU and insert the positive probe into where the yellow wire is, and the ground wire to one of the two middle black wires. And while you're at it, you may as well measure the 5v, since its just the red wire on the other side of the connector.
And dust out your heatsing while you are at it. :P
