Hey! I've been struggling with this for a long time. It started back when the computer would randomly cut out of the screen even though it was still running. Sometimes it just restarts on its own without saying anything. This used to happen once every week or sometimes over days, then stop for months. Two months ago the problem came back again, but after I manually restarted and waited for the black screen to show up, my computer would actually turn on with no picture at all. Usually, I could hear about five beeps coming out of the speakers telling me that there was no display output detected (since it's an AsRock motherboard). After reseating some parts and restarting the BIOS, things came back mostly normal, but a black screen still showed up for a few seconds or minutes after the computer turned on. This happened every single day for several weeks until those fixes stopped working altogether. The five beeps with no display. Reseating the CPU, RAM, and GPU didn't help, either did resetting the BIOS or checking if the power cables were connected properly.
A few days ago when I managed to get my PC to turn on at all, I tried updating the BIOS, and this seemed to help for a while because the computer would boot normally without turning off randomly again. But then a few days later the problem came back. What has helped me so far is waiting about an hour with the PC turned on (no picture showing), then shutting it down and turning it back on again, which gives me my display working. I'm really worried about the graphics card though: every time the computer boots up without giving me a picture, it keeps going back and forth between normal speed and max speed, kind of like a car revving its engine. This happens all the time as long as there is no display. Thanks in advance for anyone who helps out! Here are my specs: RAM is an XPG Gammix D30 with 8GB at 2666MHz DDR4 CL16, the PSU is a Cooler Master MasterWatt TUF 450W with 80 Plus Bronze rating, the CPU is an Intel Core i3-9350KF, the motherboard is an ASRock H310CM-HG4, and the GPU is an NVIDIA GeForce GTX 1050 Ti OC Cerberus 4GB.
It doesn't have to be so. Sometimes things break without being very logical about why. You can imagine how it works, but you can't really show that just by imagining it. You need to swap out the broken thing for something we know is working properly.
Thanks so much! I'm going to try getting a backup power supply and see if that fixes it.
