Question Windows launches to black screens with new gpu install

[keyston72]

Hi.

Im currently building a new pc for my office, I had everything installed and working fine running of the intel graphics while waiting for the PSU to GPU cable to arrive. After installing the GPU the PC woulld not boot. Fans wouldnt even spin. To test if it was the PSU, cable, or GPU, I installed the GPU (gtx 1060) in my personal pc.

The pc booted fine and I checked the device manager was detecting the gtx 1060 ok. Next I wanted to check the cable, so I swapped out the cable in my pc with the new cable. No boot. So I put the original cables back in. The computer booted and can hear windows starting up, but the screens are black, not even a no signal error showing.

After fiddling with the HDMi and Dislay port cables with no change, I reinstalled my gxt 1080 ti and evrything was fine. Changed the card back to the 1060 and black screens again. Ive swapped the cards back and forth a few times with the same result.

What could cause this? Surely the cable swapping couldnt kill the 1060s video output?

Welcome to the forums,, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Surely the cable swapping couldnt kill the 1060s video output?
You mean the power cables for the GPU from the PSU or the display cables from the GPU to the monitor?

If you used a cable from a different PSU brand/model to connect the card as I understand you did, then yes, you could have definitely toasted the card. PSU cables are not universal, they must be used with compatible PSUs. So if you used a 8-pin from a Corsair PSU and connected it to a Thermaltake PSU, for example, you might have killed the card.

Hi JayGau
The cable I bought was corsair, not sure if the same model as the PSU in my case though.
I have used a generic brand adaptor from the 8 pin male (splittable to 2 x 4 pin) to a plug that splits to a 6 and 2 pin as the GTX 1060 has a 6 pin female socket. spent a while trying to get the 8 pin (2x4) into the GPU. If the GPU was fried wouldnt windows not boot at all?

Another topic on the side. I'm planning to upgrade my pc from the specs mentioned previously to the below -
CPU - i7 14700k
Cooler - Noctua NH-U12A black
Motherboard - MSI MAG B760 Tomahawk Wifi DDR5
Ram - Kingston 64gb (2x32) 64 Fury Beast 6000MT
SSD - Samsung 990 pro 2tb with heatsink
HDD - 2 x WD Gold 2tb
GPU - ASUS PROART RTX 4080 super or RTX 5080ti when they come out
PSU - Corsair RM750
Case - Not sure if its SAMA or SAIVIA atx
OS - Windows 10 Pro
Monitor - 2 x MSI 24 inch

I'm hoping Nvidia have a price adjustment when the 5080ti comes out as they did when the 4080 super was released.
Where I live in Indonesia currently can get a PROART 4080 Super for around 22 million Rupiah (2200AUD)
5080s are the same price although there are no proart. Dont want a huge monster with rgb really.
I've seen a lot of negative reviews for the 50 series. Would I be better off going with the 4080 Super?
I dont play games so the fake frames thing doesnt concern me.
Mainly need a bigger GPU as my 1080ti is bottlenecking my creativity in UE5 as a lot of new rendering features require RTX.
