Hi, my name is Ryan, recently I do not know what happened but when I wake up and turn on my computer, it turns on for awhile and than shuts off immediately. Pressing the power button again does not work. The only way is to switch off the PSU and try again, however, no matter how many times I tried, the results stay the same.
Presume today is 1st August 2015, 1/8/2015. I woke up and switch on my computer, everything is fine through out the day, did some web browsing, gaming, work, and what not. Everything is working fine, im just having fun with my friends playing some League of legends. All is fun and all but soon we have to go to bed, maybe around 1 - 2am. As usual, I shut down my computer normally and then went to bed.
Next day 2nd August 2015, 2/8/2015. I woke up and attempted to switch on my computer, thats when the problem occurs. the power led lights up, the case fan starts spinning, but in just 1 or 2 seconds, everything stops. The power led is no longer lighting up, and the fan is slowly coming to a stop. I tried to boot up my computer again by pressing the power button but nothing is responding, it was as if the computer died. So I switched off the main socket/ the power supply and waited for awhile. After about 1 minute, I tried again. The same problem occurs, the power led lights up, the case fan starts spinning, but in just 1 or 2 seconds, everything stops. The power led is no longer lighting up, and the fan is slowly coming to a stop.
I thought to myself, just give it some time before trying again so I went outside for breakfast and came home at around noon. I tried booting up my computer again and the same problem occurs.
After a few days of searching up google with my phone, many say that its best to breadboard your computer to see which part is causing the problem thus I did that. I removed everything the RAM, the GPU, the HDD, the ODD, the heatsink, the case fans, the mobo, the PSU but not the CPU as its quite a fragile component thus I want to avoid interaction as much as possible.
I removed everything and placed them on the floor before doing some cleaning. After cleaning, I reinstalled the mobo (with the CPU still in it), reinstalled the heatsink, and reinstalled the PSU, connecting my power switch and led switches appropriately and tried to boot up my computer again, this time, taking a video. This is what happened: https://vid.me/gq7Z (A), https://vid.me/4DpW (B)
Video A shows what happens to my cpu/ heatsink fan when I attempt to boot up my computer,
Video B shows what happens to my power led when I attempt to boot up my computer, if you look carefully, you can also see the cpu heatsink fan stop spinning
Here are my system specs (Had it for 2 years)
Mobo: Asrock H77 Pro4/MVP
Cpu: Intel core i3-3220
Psu: SeaSonic S12II -520W 80 plus Bronze
Ram: Corsair vengeance ddr3 8gb 2x4gb 1600mhz
Gpu: ASUS GTX550 Ti DirectCU
HDD: Going to change one once this problem is fixed so it probably should not matter, I had it for 5 years plus already
Cooler: 2 Stock Case fan (going to change), Gpu's dedicated fan, and a heatsink fan for cpu
Case: Antec Three hundred two
OS: Windows 7 Home premium
I kind of breadboard-ed(In a case) my computer isolating only the Mobo,Cpu and the Psu and the same problem occurs.
[Updated] Here are some videos I took:
Would really appreciate any help, I have no idea which part is causing the problem thus unable to solve it
