My GPU overheated and died, but can I tell if there might be issues with my PSU as well?

Hello everyone on Tom's Hardware.

Two nights ago my GPU crapped out while playing League of Legends.
- Screen tearing.
- Artifacts.
- Odd colours.
- Constant driver crashes
- Eventually BSOD.

Afterwards when attempting to boot my system, I immediately get screen tearing to a point where nothing on the screen is identifyable as any kind of shape other than random streaks of colour.

It is important to note: My Motherboard has no on-board graphics so my GPU is used at least in part to display BIOS, which is why I am almost sure (but not entirely) that it is just the GPU that has gone bad.

Sometimes it makes it past Bios and through the windows loading, but immediately upon leaving the "starting windows" splash it crashes with a BSOD.

What I worry is...
that my PSU might also be bad since the screen-tearing etc happens even before the computer has loaded past Bios, but as stated there is no on-board graphics on my motherboard. The only connection to my monitor is through my GPU.

IF my PSU is also bad could it potentially damage the new card?

Note: The card has been dying for some time. It started with the second display port not working, for a week, then sporadically failing until a point where it was completely broken.

The only option you really have is to take your system to a computer shop and asking whether they can install a test PSU, which they know works properly, to check that possible situation. Normally though, if the PSU isn't working...

Nvidia Geforce GTX580

Unfortunately I no longer remember what brand my PSU is. The computer is 3 years old at this point, and I misplaced the shipping order where all the components were listed when I moved two years ago.

It took a little while to get the PSU out to see the label (it had been installed upside-down) so fan was facing into the cabinet and the label was up against the frame of the case.

PSU
- Make: Chill Innovation
- Model: CP-1000M 1000W
- Link to specifications

GPU
- Make: MSI
- Model: N580GTX - M2D15D5/OC
- Link to specifications

MOBO
- Make: Asus
- Model: P6X58D Premium.
- Link to specifications

So like I mentioned in the OP, there is no onboard graphical capability on the mobo.

I can't find a lot of information about that PSU. It could be that voltage ripple from the PSU has caused the GPU to go bad after a while, but there's no way to tell.

I know you can't boot into windows atm, but in the BIOS can you see any temperatures for your GPU? If not the GPU then the system in general?

You say the PSU was inverted, was the cooling fan blocked? If so it's possible the PSU overheated, became damaged and has taken the GPU with it, in which case it would be wise to replace it.
Whatever the cause it sounds like the graphics card is dead, artifacts and screen errors during POST/boot are hardware not software related.
With no onboard graphics to test the monitor all you can do is to beg/steal/borrow a known, working card, install it and see what happens, no need to uninstall the current drivers, the temporary replacement will work off the Windows basic VGA drivers.

I cannot even read the BIOS. The tearing happens immediately upon booting now before anything at all loads.
I checked the monitors by connecting my laptop. They are fine.

This is why I am a bit mistrusting of my PSU. The card doesn't even make it to displaying BIOS, and with no on-board GPU I don't know if there is anything I can do to check the PSU.

Normally though, if the PSU isn't working properly, you'll get no life in the system at all, or the system turning off and on every few seconds.

A couple of things you could at least try: Again in the PC shop see if they have a test GPU they could install to see what happens there, or before that, you could try using a different output, I would try HDMI or DVI as you said that your second DisplayPort has died, could be that the first DisplayPort has now died

Thank you for the answers. It has been helpful and informative.
It will be a little while before I can acquire transport to a hardware store for me and my PC since i live in a rural area and have no car.
Though the method of elimination is likely a very good idea, so I will do that.
