PC doesn't post

[david2000riedel]

So my system isn’t booting right. My motherboard lights up a white led, which is named “vga”. Sometimes it posts and runs relatively smooth. Also my cpu runs hot after 5 minutes during no tasks (60-70°C).
The PC itself is turning on. Every led of each part is running but I don’t get any video signal. I tried switching monitors and cables, doing a clean ddu and new driver install, checking if all parts are connected to the motherboard and the psu, nothing helped. The system sometimes post, but the cpu is running hot. It stopped posting tonight.

Psu: be quiet straight power 11 850w
Mobo: asus tuf gaming b550 plus
Cpu: ryzen 9 3900x
Gpu: rtx 3080 gigabyte gaming oc
Cpu cooler: wraith amd stock fan
Ram: corsair vengeance 16gb 3400mhz
2,5 tb ssd (0,5 tb 850 evo and 2 tb 860 evo ssd)

Hello

Is the pc down? If not run this and then post that log on the voltages..

Hey, thanks for your response, but the pc isnt giving any video signals.

Do you have on board graphics?

@Bruce

Apparently not. Ryzen 9 3900x doesn’t have integrated graphics.

I tried to create a log-file. It doesn’t display the moment my system stopped working. Do you need the log file containing the moment the problem occurs?

“Do you need the log file containing the moment the problem occurs”

Yes if all possible..

Here you’ll hopefully find the data you need. It was recording the log during the signal loss.

I experienced a new aspect of it: When I turn on my pc and wait for it to boot on my tv, it is booting up to the windows lock screen. When I enter my password it shortly transfers to my desktop, but after a second or so, the signal disappears again. If I switch between tv (4k) and my monitor (full hd), disconnect each hdmi-/dp-cable and connect it each seperately, no signal returns. But if I boot my pc just with my monitor connected, it boots just fine (just with relatively high cpu temps). If I switch over to my tv now, the signal is lost again. I tried different hdmi cables connected to my tv, but nothing helped. I don’t believe it happens due to my tv, because it worked fine for a few months already (bought it in august).

Now, it is working on the tv again, but not for long I believe.

I suggest that for now you keep the PC disconnected from the TV and look into the high temperatures that you mention, you are likely to fry the CPU if you don`t.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Hey, thanks for your response. I made a snapshot.

while it’s working on the monitor (agree - let’s forget the TV for now) do yourself a favour and get your backups in order.

then, I’d pull the memory and GPU out, wipe their contacts and circuitry with a soft brush and also their mobo slots.
clean the GPU fan and re-seat them all back in.

take off the CPU and also give it all a brush, apply new thermal paste and also clean the heatsink and fan.

check the RPM’s of the fans via their settings in the BIOS and see if all that helps with the temps.

All the parts (GPU, CPU and MOBO) are fairly new and pretty clean. I hardly doubt that the contacts are responsible for the problem.

no sweat.
