Help! PSU or Mobo dying?

[kingsen]

My PC is having some problems and currently cannot boot into windows.
Previously already showing symptoms of : PC able to boot , but monitor going into Power Saving mode, means PC is running but monitor cannot display. After some time it will work again. But on and off it will happen.
Today while playing overwatch , my PC suddenly shut down itself. Den it tries to restart itself but after 5-10sec it will shut down again and tries to restart again. I have totally no clue about this problem.. could it be PSU? Mobo ? RAM?
I do notice when it shut down and restarts, the CMOS light did light up at the rear of my CPU. I not sure whether izzit normal for that to light up during booting tho.. Currently able to use normally again.

Anyway here is my setup:

- I5-3570k
- ASRock Z77 Extreme 4.
- MSI GTX 970 Gaming
- G.Skill Ripjaw 1600Mhz (2x4gb)
- 120GB Intel 520 Series SSD for OS / Western Digital 2TB Caviar Black 6Gb/s / Samsung EVO 250GB SSD
- Dell U2713HM monitor
- Creative SoundBlaster Zx
- FSP Aurum 550W Gold Modular
- Windows 10.

I also notice that whenever opening up files stored in my HDD , it will take some times to load the folder , not instant as compared to the past.

A lot of people made a thread regarding their PC shutting down in the middle of gaming and then trying to turn on for a few seconds and then shutting down again.
With you saying that you have an FSP brand PSU, even more chance that that seems to be the cause.

For HDD being slow, is it the WD HDD? If it is, run a smart test on your WD HDD after you get your PSU issue resolved. But if it getting even much slower, I would advice you against using the drive unnecessarily and quickly buy a new internal or external drive and copy files of about maybe a folder each starting with the most important over to the new drive. Before your drive slows down and goes kaput altogether.

My guess is the mobo.

Can be windows also.
Can reset windows to factory setting to test.
