PC Black Screen on Startup

[Knosseus]

Today, while playing a game, my computer suddenly blackscreened and refused to show anything on the monitor. I tried rebooting the computer the monitor was flickering and then went to blackscreen again. On restarting a third time, the computer showed the 'Press Del or F2 to enter BIOS' text and then immediately blackscreened. 

 

I used my laptop to confirm that the monitor is still fully functional. 

 

Note that the computer will not display anything more than the 'enter BIOS' text despite using either the HDMI port on the mobo for integrated graphics or the GPU HDMI port. 

 

The light on the monitor is green, indicating it is receiving a signal from the computer. 

 

Troubleshooting steps I have tried:

 

1. Turning monitor on/off - Nothing. 

2. Booting into Safe Mode - Can't tell, computer blackscreens before I can see Windows. 

3. Reseating GPU - Nothing. 

4. Resetting CMOS - Nothing. 

5. Reseating RAM - Nothing. 

 

I don't know what caused this problem since this computer has been working fine for approx. 2 years. 

 

Any help is appreciated!!

CPU: AMD Ryzen 3 2200G

RAM: 1x 8GB G.Skill Aegis @ 3000

GPU: Asus ROG Strix RX 570 4GB

so it does display? just not after os handoff?  try your igpu to see if it has the same results.

igpu has the same result - blackscreens after enter bios text.

i would try to boot from a live linux usb to check the boot ssd.

[Knosseus]

Just tried to open BIOS to boot from USB, but blackscreens before BIOS appears.

With GPU unplugged? Also remember to quote or mention the guy you're replying to

I tried both with GPU power unplugged and GPU completely removed - same problem, blackscreen after enter bios text.

did you enable XMP or anything of the sort? tried the ram in other slots?

I had XMP enabled to run my ram at 3000mhz, the rated speed. I haven't tried the ram in other slots, will try now.

try running without XMP

How can I do that without getting into BIOS? PC blackscreens before I can get to BIOS

reset the CMOS

 

i think the 2200G is either zen1 or zen+, both doesnt handle above 2933mhz well

i would try running at 2933mhz or 2666

I just tried the ram in the other two available slots (one closest to CPU is blocked by CPU cooler), similar results. In the furthest slot I managed to open the BIOS for a split second before it blackscreened.

I already reset the CMOS by removing the battery and adding it back ~10min after. I assume that means ram is running at base speed right?

unplug PC from the wall, push the power button twice, wait 10 seconds then, short the CLR_CMOS pin near the bottom right of the board for ~5 seconds

I don't see a CLR_CMOS pin, only CLRTC_CHASSIS in the bottom right.

it's called CLRTC for your board, as for the location... it's normally on the bottom of the board

not too sure what _CHASSIS means, a pic?

i googled an image, blurry one, but it should be it

Anyways I did that with the CLRTC_CHASSIS pins in the bottom right, no change.

After rebooting again I'm getting an American Megatrends logo and text page for a second, then blackscreen.

unplug everything from the motherboard,

other than cpu 4/8pin, 24-pin, RAM, and CPU

plug in keyboard and your monitor to the rear IO, nothing else

front panel connectors can be left untouched, make sure nothing is plugged into them in the front

 

if this doesnt work then either your RAM,CPU, or motherboard is dying/dead

Did as you asked, blackscreened on 'enter bios.'

 

Hate to hear that my computer is dying, probably the RAM if I had to guess. I didn't mention it here but I was running an error last week with Malwarebytes running into ~10-15 hard page faults per second. Error went away after uninstalling Malwarebytes, so I thought it was a conflict of some sort. Probably the ram that's gone then?

im suspecting either RAM

or CPU's memory controller, from being stressed from running 3000MHz

or motherboard's VRM just burnt out

 

perhaps you can buy another stick of similar ram, use that as diagnostic, since it's recommended to run dual channel RAM anyways

 

both your CPU and RAM should still be under warranty, not too sure about motherboard

tysm for all your help diagnosing! Will look for a new stick of memory to test with and see from there. 

 

Thanks again!
