PC Won't boot When GPU plugged in

[scoutmasterkb28]

Hi Everyone,

 

My PC seems to not boot up when I connect my PSU to my graphics card. This happened when I was booting up a game and my PC crashes without any BSOD with a burnt smell, similar to burning plastic. I opened up my PC and did not see any signs of short circuitry and burns. I reassembled my PC and it won't boot up. I tried unplugging certain components and it seems that my PC will boot up if I don't plug in my GPU with my PSU. So for now my GPU is plugged into my motherboard without the PSU wires and the system doesn't recognise that there is a GPU. The GPU still lights up though

 

My current specs are
Cpu: Intel I74790k
Windows 10 Version 10.0.14393 Build 14393
GPU: MSI GTX 980(Driver 375.95, DDU everytime I instal a new driver)
MB: MSI z97 GAMING 3
PSU: CoolerMaster Vanguard 650M
RAM 8GB(4GBx2) DDR3 memory
Cooling: Coolermaster V8 GTS
Case: Coolermaster HAF912

I have my PC on surge protection by using a UPS.

 

I'm wondering how to solve this. I'm thinking it could be the GPU or the PCIe slot that is faulty. Can someone help?

did you check the caps on the gpu

Full specs please

check your GPU and PSU, look for blown capacitors, the little cilinders on the PCB. you may have to remove something like the heatsink to see all of them. and ofcourse look for any signs of physical damage. also check the motherboard, especially around the PCIe slot. if you are going to open up the PSU, please be carefull because the big capacitors in there can hurt if you touch them, so only do that if you know at least some basic physics, preferably wear some rubber gloves or something.

Do you ahve a friend that could lend you a PSU or GPU? If you can borrow a GPU that is known as working, then that would be an easy test... preferably one with a similar power usage. I suspect it's the PSU personally.

I didn't manage to get measure the caps on the GPU and now my OS isn't detecting my GPU as it's not plugged into the PSU.

I'm not sure about the PSU, I have replaced my PSU 6 months ago which I would not think it can be faulty. I don't have anyone who could lend me a PSU or GPU for the time being.

It's not a question of age for when a PSU fails, or any other component really, components can fail at any time regardless of age or how much use they have had. It's just being unlucky, if you manage to get it tested and it is the PSU, then you can claim under warranty.

So I tried plugging in a different PSU and the same thing happens. Would this mean that the GPU is faulty?

Could be then. Does your PC operate normally when you have no discrete GPU installed? Did the PSU that you tried have enough wattage.Ampage for the system? there could be other factors, but if the PSU wasn't up to the task, then it might not have been a proper test. Have you got a friend that would let you put your GPU in their system to test it?

The GPU is a slightly higher wattage that I normally use, 750W when mine is 650W. He has a similar setup as mine. for now I don't have anyone to lend a GPU since that is one of the expensive components that my friend has. Is there a way to test for a faulty GPU that wouldn't take any PSU?

NO, I was saying put YOUR GPU in THEIR system to test it. I don't know of another way to test the GPU without going to other methods like testing electrically etc... and I'm guessing that you wouldn't have the equipment or knowledge required for that, as you'd already have done it.
