PC black screen, loud fans on boot. Temp fix by unplugging power

[[DisZeLegend]]

So Ive been having this wierd issue. I recently buit a new PC and everytime I boot it up after its been shutdown for awhile the fans spin up loud and the screen doesnt boot up. However I can sort of fix this by unpluging the power cable and replugging it in and then it boots fine again (even when I restart the pc it boots fine, problem only shows up after its been shutdown for awhile). Not sure what the problem is. Updated bios and drivers and reseated the ram. Video card is plugged in and powered. And as far as the temps ago it seems alright. All the parts in it are also brand new. Other then that the PC runs perfectly fine. Just really annoying I have to constantly reach back and unplug it everyday to boot it up......

specs:
MSI z370 mobo
850w psu
MSI rtx 2080
i7 8900
2 8gb ddr4 viper ram

I suspect motherboard or PSU is failing.

As for the Fans it's quite common for them to kick it at full RPM briefly when a system is powered on and drop to normal RPM for current CPU temp shortly after.

[_I_]

fans at full speed at boot is normal, til bios or windows tells them to lower

check bios boot settings
try disabling fast boot

If the fan is still going after shutdown, it means a couple of things.

1. Your computer isn’t shutting down properly (turn off Fast Startup in Windows 10).

2. Your CPU and motherboard are extremely hot after use. Sometimes it’s common for fans to continue running until the GPU and CPU are able to cool off. That’s especially true if you’re using a stock CPU cooler.

What’s the make and model of your case? Is there room for any extra case fans? Where do you have the PC located (usually 3 inch clearance from its cubby hole is what you need)?

Those are all factors into what’s going on. And as Suicidle Monkey states, this is pretty much a normal thing to not worry about on Startup or shutdown.

Thanks for the replies guys. My only problem with this is that its a little hard to reproduce. It only has the starting issue when its been shutdown for a long time. I can really only test it if my pc seems to be shutdown for about aa minimum of 3 hours. Tried disabling the fast boot but still didnt seem to work.

Again the problem is that when the PC boots (after its been off/shutdown for sometime) all the fans spin up loud AND that the monitor does not go on. The only way to fix or bypass this seems to be turning off the power switch or unplugging the power cable from the back of the PSU. After that it boots up just as normal and if I wanted to I could restart it without runnning into that same problem. Im starting to get worried that its something to do with the video card. :( Really dont want to deal with mailing it to msi

Are you using a cpu extension cable?

Nope, same cable that is directly plugged into the psu

Have you tried plugging your monitor into your motherboard instead of the GPU?
Is there anyway you can refund your psu? What psu make is it

The make of the PSU is Corsair, have not tried plugging into the motherboard yet though. Can still return that though. Ill probably plug the display cable in the mobo before I shut it down tonight

Ok it may be the psu or graphic card,
If that doesn't help go into the bios and reset it to default, and if you want, update the bios.

Thought it was doing fine yesterday but this morning ran into the same problem. Im going to try to swap the psu for a gold rating or higher instead of the bronze and HOPEFULLY return the gpu for a new one.

On a side note I find it really wierd IF it had something to do with the video card only cause when my PC gets pass this booting problem it performs perfectly fine! Have not had a single crash from playing any games. Even put it through its paces in VR and no crashes....

Thats the issue with intermittent problems, not just with computers either. Can make it difficult to isolate the cause and solve the problem quickly

Did you ever manage to sort this, having the exact same issue ?

[Carlsberg]

I have heard that disabling fast startup in windows control panel solves this issue for some, Seems to be a gpu driver issue.

Happened to me a couple of times, (also have rtx 2080), I am using driver 441.66 and its not happened since I installed this driver and i have fast start enabled.

update for myself, have tried updating bios to latest, disabled fastboot via bios (fastboot option wasnt given on windows for some reason ). no joy with this option

what i have tried now is switching my psu (corsair vengeance hybrid 750m) to single rail from multi rail

rtx 2070 super

so far booted up three times with no issues, hopefully this was the fix, will update once i give it a a week or two.

I’m having the same issue now, a bit late but was wondering if you ever fixed the problem, if so how?
