After restarting the PC, no video appears because of a freeze.
Hey forum, I hope you're all doing well. The problem is that my PC isn't showing any video on the monitor even after a hard reset. It froze completely during a game, and once it stopped, there was no sound through the headphones. I thought maybe the hardware overheated because I haven’t cleaned it up since my daughter was born. After turning it off, I tried to power it back on, but the monitor didn’t respond at all. All the fans—CPU, GPU, PSU, case—are spinning, and the RGB is on, but nothing displays. I cleaned the whole system thoroughly, reapplied thermal paste, checked the GPU connections, even tested HDMI, but still nothing. I looked online and thought it might be a GPU issue, so I tried my old one, but the monitor didn’t react either. Also, I wondered if the power supply could have failed, though the fans are still running and providing power to other components. Any advice on what might be wrong or how to test the PSU would be really helpful. My specs are: Mobo AsRock B365M PRO4, GTX 1070, i3-9100F CPU, 2400 MHz RAM Corsair Vengeance 2x8GB, Corsair RM650x PSU, SSD1 Samsung Evo 860 GB, SSD2 Samsung Evo 970 Evo+ 1TB.
Looking for help with a possible dead GPU issue. Would you like to try it on another computer or borrow one to check? Keep an eye on the debug LEDs during startup.
The most reliable way to check the PSU is by swapping it with a verified good one. If the replacement works, your original unit is likely defective. Computers can fail suddenly due to many parts like RAM, CPU, GPU, SSD, or motherboard. Testing the GPU is straightforward—place it in another known working system and verify signal output. RAM testing is similar but requires compatible hardware. The CPU demands a matching socket, though possible. SSDs can be evaluated on another machine or using an external USB adapter. Motherboards are the trickiest; typically you inspect other components first and suspect the board if none fail. Based on your skills and parts available, consider taking it to a repair shop and request a quote before proceeding.
I changed the GPU and the monitor still shows no signal. I’ll look into the LED next time I’m back from work and will update you. As discussed before, the GPU shouldn’t be the issue since the new one gave me the same outcomes. My thought is a power surge might have damaged the PSU. I’ll try getting a replacement to see if it resolves the worst case. If it doesn’t, I’ll return it.
Discovered a failed RAM stick affecting video output unexpectedly. Issue resolved, case concluded.
