Just yesterday I was able to use my PC perfectly fine but this morning when I tried to turn it on, It shows a "no signal" on my monitor.

I've tried a number of different methods but none have work. I have tried taking out my CMOS battery for 5 minutes and checked if all cables were seated properly. I've also tried a different monitor to see if it works and it did not. I tried connecting the monitor to the motherboard DVI port and still nothing shows up. I have NOT tried using a different graphics card maybe that might be the problem? Only reason why I haven't tried it is because I don't have another card to test it with. Also haven't tried toying around with the BIOS but I'm still able to get into the BIOS, just not into windows.

I noticed that when I power on my PC, all the lights and fans are working so I assume that the PC is on and should be working. When the PC launches I see the little swirl icon before windows starts but after that, the PC just shows "no signal" and goes into a black screen.

Anything helps! Thanks!

Did you happen to notice a windows update when shutting down your pc last night?
I've had a similar issue before (not so bad) and basically windows had a conflict with bios and my drivers after an update.
Maybe if you have a hard copy or flash of windows plus it in and see if your pc registers it


MSI B350 Tomahawk
Ryzen 5 1600
Corsair Vengeance LPX 2x4GB
ASUS r9 290
EVGA 650 g2
Samsung 860 evo

Can't press CTRL + ALT + DEL after the blank screen. Keyboard doesn't seem to work during the blank screen but works if I access the BIOS.


 
Which PSU model do you have?
Connecting a cable to the motherboard would not help since there isn't any iGPU on that system.
Try other ports (DVI/HDMI/DP) from the R9 290, if the issue remains then you could rule out the cables and monitor.
It could be the GPU, its drivers or a power issue.
