Question Windows loads to a blank screen after motherboard swap.

[Barney6262]

Hi all,

Just swapped my motherboard and CPU to I9 9900K. Had it booted up and fully functioning whilst on my desk and played around with the AORUS app centre program.

Turned it all off to put the pannels back on and put the case under my desk, connected all my usual cables and pressed the power button. Mobo logo shows up, windows logo with spinning dots for about 10 seconds then screen goes black/blank. (monitor still lit up, just literally black).

Cant seem to get past this stage. Tried troubleshooting startup issues multiple times, always comes back with nothing. Tried restoring to various points prior to mobo change, just ends up rebooting to the black screen again.

I can start the OS in safe mode but if I try and do a clean boot I get the same black screen.

Any ideas on what I could try as I really don't want to be reinstalling windows.

Thanks

That's really unfortunate to hear. I believe I had the exact same problem you're experiencing with my EVGA GTX 1070 FTW card that was a year past its warranty. I had thought it was a motherboard fault or compatibility issue between mobo and gpu but after buying both a new mobo and PSU (to rule that out), the GPU that worked on my old build, but not the new setup is the culprit. Even though the gpu worked until I swapped it into new pc, there seemed to be some sort of power regulation on the gpu that went to fault. EVGA never told me exactly what was wrong with my card, but after calling customer support, they were able to set up an RMA for my 1070, and replaced it with a 1070 TI that booted up first try. Probably a faulty GPU at this point.

I suppose this is possible too as the 1080ti is a used card.

A new psu is about £120 while the 1080ti is much more than that so I might try the psu option first and hope for the best...

You said you tried your friends PSU with the card and had no luck right? I dont think a new PSU will fix your issue, but I do understand the cost difference to try. I'm almost certain it's the GPU at fault, if your 1070 works in the new setup just fine.

Yes I tried my friends PSU. Both PSU's are EVGA 850w G2 so if they dont supply enough power then it would make sense that both gave a blank screen as they did. But again, as far as I know 850w should be enough?

I'm starting to suspect the gpu yes. It just strikes me as odd that it worked in my old system for ages with no issues AND in my friends PC. We could literally swap it back and forth with 5 minutes between being installed and it would work in his but not in mine. If the card is broken surely it wouldn't work in either system??

Are the motherboards the same? I was thrown off by the same, if the card works in another build but not the new one, it certainly cant be the card right? Unless you both have the exact same setup, with cpu, mobo and ram being the same, the card working in his but not yours could be down to the overall draw for the new system preventing the card from powering. 850W should be plenty for a non-SLI setup.

You say the black screen happens after Windows logo shows up? That sounds like a driver issue then if you can get the system to bios and post to windows logo. If you havent successfully installed a new copy of windows 10 since you changed motherboards, I'd do that. Then I would use DDU to remove any windows installed drivers. Then you want to turn off automatic updates for windows, so you can manually update your nvidia drivers. After you've installed your graphic drivers, re-enable automatic updates for peripherals etc.

My friends build is almost totally different apart from the psu. Much lower wattage cpu.

Again though, I was under the impression that 850w is enough for a stock 9900k and 1080ti.

I've been through all the steps you detail in your second paragraph unfortunately. Can get the card to work in safe mode and it's recognised in device manager as a 1080ti but as soon as I start in normal mode I get a black screen. Initially thought it was a badly installed driver but unless I'm missing an option in bios there's no way it's that with the amount of times I've redone it.

I'm assuming if the drivers are not loaded like in safe mode the card doesn't draw its full tdp?
