Hi guys,
I just build my first ever PC a few weeks ago and it was working as I expected it would. Now 3-4 weeks later, when I press the power button it powers on and then shuts down 1-2 secs later and then restarts 2-3 secs later and shuts down again. This process repeats itself until I switch off my PSU. I don't get to see a POST. (System specs below)
Things I've Tried
1. Resetting the bios
2. Powering it on with with multiple combos (motherboard and 1 stick of ram... *tried both sticks in case one was faulty*, with SSD, with HDD, without SSD & HDD, and without GPU.
3. I unplugged all components and did the self test which in on the PSU (Corsair AX760i) and it passed (green light & fans spinning).
4. Unplugged everything from the motherboard and checked for bent pins or any obstructions in ports.
5. Plugged all the components back in but in different ports on the motherboard and PSU.
Now I should note that after each of these steps the computer powered on fine and I was able to run stress test to see if could find an issue with the hardware. I even tried multiple manual reboots and a few hard reboots to see if the problem would persist and it didn't during my testing each time. However, when I shut it down and leave it overnight or maybe a few hours, it again refuses to power on and its right back to square one.
Things I haven't done at the time of this post
1. Remove the motherboard, cpu and cpu cooler. The reason for this is because I haven't been able to get thermal paste as yet so I wouldn't be able to continue testing. So at the moment this is a final option.
2. Booting in safe mode and testing.
3. Wiping my system drive and reinstalling windows.
4. Swapping out components. (first build so I don't have spare parts to fit) I do have my intel stock cooler which I'm wiling to try once I get some thermal paste. (The new CPU cooler was installed a week or so before I started having problems)
