• My monitor loses signal
• all my peripherals stop working
• The pc seemingly stays on for a few minutes (the rgb doesn't turn off)
• The pc finally shuts down.
• I've tried multiple things to fix this issue. I've reset my bios by removing the battery from the mobo, and I've reseated my gpu and ram. Somehing to note is that sometimes the pc emits an odd smell, like a burning smell. Can anyone help me fix this to get my pc working again?
• (AMD Socket AM3 unrelated, i just picked that because the forum told me to select a device)

So I have been struggling with this for about a year. When I start my computer up one of 4 things tends to happen.

1. black screen/no video signal detected and the computer will shut off immediately after pressing the power button. Very little sound from the computer.
2. black screen/no video signal detected and the computer will require the 5-second hold to power off, sound is louder.
3. bios screen pops up telling me I need to fix my boot device, there are no boot devices.
4. The computer starts up normally.

This used to take one or two tries but now is a 10-15 minute ordeal of powering it on and off until it works.

What I have done:

1. checked to make sure the hard drives are connected properly.
2. Changed the cmos battery
3. updated the ssd
4. updated the motherboard
5. replaced the power supply
6. used a different monitor
7. sacrificed a goat to the gods of pc repair

Nothing has fixed this so far. Any help would be so greatly appreciated. I may even name my next child after you if you can help in any way!

Specs:

Asus P8Z77-V PRO

Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz

16gb ram

760w Seasonic x series

SSD

My friend approached me earlier today and said his high-end pc won't output to a monitor via DP. I tried to help him over the phone but he asked i pick it up tomorrow so i thought i would get some advice before i start troubleshooting.

Here's what i know so far:

12900k

3090

pcie 3.0 riser (Says he's gone to bios and set link speed to 3)

Apparently only works on HDMI

Apparently has bad drivers (I am unsure though)

anyone who has any thoughts/help would be strongly appreciated as he just build this only to have it not run his games. I will update this thread once i get the pc and more info

(going more in-depth about the keyboard is that it works fine most of the time but sometimes it randomly repeats a key after input and will only stop after I input another key. If I don't interrupt it, it repeats indefinitely)

 I plugged in my cousin's keyboard and the same issue still affected his keyboard so I know it isn't a problem with the keyboard itself. I've done constant searching, troubleshooting, reinstalling drivers, and even reinstalling Windows to no avail. No articles, videos, or forums on Google or youtube have helped.

 We've been thinking maybe that it's a motherboard issue and are considering replacing it as a last resort.

 If anybody has any advice, tips, feedback, or anything that would be helpful at this point, I would greatly appreciate it.
