Question 2nd monitor bricked PC?

[dylancs]

I built a computer around 3 months ago and experienced no issues whatsoever. Decided to purchase a second monitor a few days ago.

Got everything set up and after ~30 minutes of using it, my PC blue screened. I’ve been stuck in a BSOD loop since, tried to reinstall windows and I BSOD during the instillation every time.

I’ve heard of faulty drivers due to HDMI causing BSODs, but surely unplugging the cable or booting in safe mode would fix it, right? Not for me.

Wondering if, somehow, a faulty HDMI cable or driver of some kind could have caused this, and what component it could have damaged? It could definitely just be a coincidence, but very suspicious that not too long after making the only change to my setup in the past few months, my computer is essentially toast.

If anyone has any ideas before I start replacing things and/or head to the repair shop, they’d be greatly appreciated!

CPU: Intel Core i5-13600k
GPU: ASUS DUAL RX 6700 XT
RAM: 2 x 16 Corsair Vengeance LPX DDR4 (3600MHz)
Mobo: MSI Pro Z690-A DDR4
PSU: Corsair RM750x
Main Monitor: Dell s2522hg (via GPU DisplayPort)
(New) Second Monitor: Acer KA2 (via GPU HDMI)

Welcome to the forums, newcomer!

You might want to try and work with the iGPU and with only one monitor. Also try and clear the CMOS for your motherboard after you've removed the discrete GPU from the build.

Yeah as mentioned, Take the 6700 xt out of the system and see if the intergraded GPU will display anything, if it boots like normal, Install the 6700 xt and see if you can get a picture from it, I have had something like this happen on a GTX 1070, somehow plugging in a monitor corrupted the drivers, my only guess was there was some static and and caused the GPU to reset and after a forced reboot messed things up, Rare but can happen.

Also make sure all the cables are plugged into the 6700 xt fully, same with the 8 pin on the motherboard, and 24pin, I know its hard to jar them plugs loose, but I've seen it happen, usually from not plugging them in fully, and eventually they work their way loose enough to not make contact.

If the system still doesn't start after taking the 6700xt out of the system, reset Cmos, can pop the battery out of the motherboard which should unplug the system from the wall first, hold the power button down to drain the power from the caps, and let it sit with no battery for a few min, the board may have a button to clear cmos as well, which typically can keep the system plugged in with the button.

Still nothing, my next guess would be Power supply.

Good Luck!

Tried both of these steps a couple days ago to no avail, so just handed it off to a repair place. They called me back today saying that it was the CPU, confirming that the 2nd monitor situation was purely coincidence, right?

Either way, I was wondering if it’s normal for a CPU to just give out on its own after ~3 months’ use, or if it was likely something wrong that I did building (it was my first build.) I’ve been monitoring the temperatures intermittently and everything seemed fine, usually sticking around 60° when gaming with quick spikes to ~75° at times (I thought it was suspicious but seems normal after research.) But, aside from temperatures, is there anything else that I can do to prevent this from happening again if it was indeed my fault somehow?

Appreciate all the help!
