Hi, I'm looking for a solution for my desktop which suddenly shuts off and having hard time to power on (until I give up).

Sometime, I succeed getting it on power on by trying these solutions.

Resit all components while dusting it off.
Replace thermal paste of cpu and reconfirm the cpu fan is working and sit properly.
Switching with my extra PSU (japanese brand) and both of them tested with paper clip before attaching to desktop.
8pin motherboard to psu confirmed.
Tighten the screw of my motherboard.

BTW I use old generation of components....

Windows 10
Processor: i7-2700
Motherboard: Gigabyte GA-Z68X-UD3H-B3
SSD: Samsung SSD 840 series 250gb
Memory: Corsair vengeance 4gbx2
Video card: MSI GTX 960 2GB
Power Supply: Cooler Master 750w / Japanese brand 700w
HDD Box external usb 3 with 2tbx2 and 3gbx1

Before creating this thread, my desktop cant be turn on so I decided to do all my solutions again and even replaced thermal paste again... after 2hrs lest my desktop turn off again.

and this time I decided to take off video card and use integrated... somehow it turned on (losing my 2nd monitor Q_Q) so I will test if my desktop will shut off again even without the video card.

what do you think guys? is the video card faulty here? my video card is like 2 years old, I think the thermal paste inside to it is already dried out because I always use my desktop almost 16 to 20hrs a day... and there are times that I don't even shutdown it.


Edit: the desktop shutdown itself again without video card... Therefor culprit is not video card... Im running out of options

Typically when that has happened in the past to my friends, it's a bad motherboard. I highly doubt a video card would do that, and thermal paste doesn't dry out because of the computer being left on - it dries out after aging a LONG time.
