If you’re lazy to read up my issue, you may read up the conclusion right at the bottom.
Things got worse to worse. Today I send my motherboard for replacement, the manufacturer staff did a test for my mobo and confirm that there’s an display issue. Therefore 1-1 exchange were successfully made. I witness that the new mobo they replace for me were up and running. After that I went home and assemble back the parts. Everything went well.. I did a serval test and still got the “old” long term issue since 2 year ago which I did below:
1. Did a 1 time restart of my computer, Totally no display from my GPU. Hence I plug out my GPU cable and plug into onboard display. Result in no display. Have to force restart on the computer everything back to normal but onboard display totally no display at all. But at the manufacturer company I can see onboard display. Back to restarting, same thing happen again.
2. First time power on after I got back my replacement, I was quite surprise that there isn’t any power on delay. I thought I was relive that everything goes well. I shut down my computer and try and power on again. I need to spam click or hold the button to start up.
3. Before the replacement, Last year got one fine day my power button magicially work without any delay for ONE WEEK. Which mean I only gently press ONE time and it will power up. After that the old issue is back which describe above on 1 and 2.
What I have RMA-ed:
Motherboard (On the spot check everything goes good)
Power Supply (Brand new sealed)
What I have test on friend house:
Graphic card (One day test and confirm that he restart serval time and next day on result in no issue. He did a same thing as above no1 no issue at all)
Current issue, after assembling back I was able to use about 30minutes then the whole system just blackout the chassis fan won’t run at all. But my GPU Fan keep spinning. Usually GPU fan will only spin when mobo sense the GPU is hot. As of CPU Fan it doesn’t even run at all, 30min before the blackout, the CPU Fan were able to run
I don’t know about this weird issue, By default keyboard numlock will on, restart com no display but keyboard numlock no on, aka cannot response anything already.
&
LAN cable usually power on got the yellow LED blinking, restart com no display but the LAN cable LED is orange non blinking.
I really dunno what can i do to fix the mysterious issue, Can anybody help me retify the hidden cause of long term issue?
I conclude that I did the following testing over the past 2 years:
1. Power up through mobo(0ms delay)
2. Tried a single stick of RAM with various slots
3. Installed my OS on an SSD
4. Unplug all power source and hold power button for 30sec-1min to discharge the voltage
5. Tried my GPU on my friends house for a day
6. Change to a BRAND new psu + RMA to a brand new psu
7. RMA-ed the Mobo(recent)
8. Tried a different RAM during the replacement
9. Hold power button / Spam click to power up(5sec-3mintues delay depending on luck)
10. Ensure that the cable is well managed
