Hey there geeks 'n nerds of this awesome website. Every time I searched some problem solving, it was here on Tom's Hardware where I found out solutions to things, however here I am, asking to troubleshoot my very own issue with my PC. I will tell you the full story of my PC what it went through so you get a better understanding of what the issue might be.
My desktop PC is like 6-7 years old put together build that I bought from one IT computer company in the Czech republic - not my own build.
Original PC specs when I bought it with warranty:
CPU: Intel core i5 2500K 3.3GHz
GPU: AMD Sapphire 6950 2GB HD ( important note: with stock cooler )
RAM: 2x4GB Kingston sticks
HDD: SAMSUNG HD103SJ
Motherboard: ASUS P8H67
PSU: Seasonic SS-620GM 620W (old one)
OS: Windows 7 64bit
Over time, I lost the warranty from the manufacturer that put this PC together, the stock cooler on GPU went nuts, one fan lost its axis and I had to buy NEW non-stock GPU cooler - Accelero TwinTurbo III cooler with a backplate aswell. All went fine from that time - no issues with the PC.
After a year or two from the new GPU cooler installation I had the urge to upgrade my RAM a little bit - I bought one stick 1x8GB - Kingston RAM and put it in the computer - so now I have 16GB RAM in total. All went good after putting the new RAM stick in the motherboard - no issues again.
Then, I had problems with fps in some games and I tried to look to overclock the CPU a bit - from 3.3GHz to something more - I am a newbie to this stuff and wanted to try it - so I got into BIOS, tried to use the overclocking tab in the BIOS, however I found out that the option to actually overclock the Intel core i5 2500K is locked. Thus, I came with a conclusion after some searching on the web, that the Motherboard I am using (ASUS P8H67) is somehow locking the overclocking of my i5 2500K that is able to be overclocked normally.
-> Now for the dumb part - I came with a "MOST LIKELY" WRONG conclusion, that after flashing new version of BIOS will do the trick, that upgrading the BIOS unlocks the overclock feature of the CPU. I have found a random BIOS (almost the same version of my actual default BIOS) - flashed it - flashing went wrong so I tried to flash it again, it suddenly worked. I rebooted the computer, everything went fine. No issues booting or powering up the computer since.
Now for my actual issue what I have right now - before like 2-3 months from now (+- august 2017), my PC started acting weird when trying to power it on. I know there were big storms in my area one or two days in a row, and that the electricity went on and off like 8 times in very short intervals. After that time, my PC started to act weirdly -
THE ACTUAL PROBLEM I have right now:
When I press the power button, PC powers up for like 1 - 2 seconds. Then shuts down for like 2-3 seconds - TURNS back ON after - and works - boots the Windows 10 and works normally. I tended to ignore this issue. On a side note, by that time, some windows 10 update came - and it did set keyboard so it was able to turn the PC on by any pressed key, so when you accidentally pressed for example CTRL, the PC turned on -> I was disabling the power button on the PSU back since (like 20 days in a row now) for when I wasn't at home - turning it back on when I got home to power up the computer.
Three days ago, I came home, turned on the PSU on 1 position, did wait a bit - tried to turn on the computer and nothing. No sign of life, however the green led diod on Motherboard was still bright green. After a few tries of turning on and off the PSU, replugging it into the computer - still nothing. So I came up with a conclusion that there must be problem with the PSU and it is probably dead and won't boot the computer at all.
Yesterday, I bought a new PSU (Seasonic S12 II 620W) and replaced the old PSU with it. Replaced, plugged in, did wait a bit, turned on PSU on the back, hit the PC power button, it did start - HOWEVER - with the same issue = TURN ON for a few seconds, TURNS OFF for a few seconds, TURNS BACK ON finally and works. I am baffled by this, I really thought it must be something with the PSU, but it keeps doing the same power up turning on-off-on problem.
I have tried the green+black pin PSU test on my old PSU and the fan in it was slowly spinning - so the old PSU is in a good shape I guess? I have really no clue, that's why I am writing this essay here, I am sorry for that but it's important to express the full backstory of my PC.
I am worried about the new PSU (I have now 13 days to return the new PSU and get a refund for it) and I am worried that it will get destroyed?? like the old PSU? So many questions.
Do you guys have any ideas what could cause the problem? CMOS battery replacement? Short on GPU from the backplate? I am writing all this on the computer that is actually working, but still with the power on issue. If you did read all this, I thank you very kindly and wish you a great day everyone. Any tips? Cheers!
