Potential PSU problem?

[engshing]

Hi everyone,

I am facing a problem with my 4 yr old DIY desktop. The desktop would crash and it will go into an endless repeat of on and off. You can hear the PC starting and then stop and this will repeat continuously until the switch is turned off.
The desktop can be start up normally after 2,3 hours. Then the same problem will happen again after a few hours of usage.

Is it possible to find out which parts is giving me problem? I am suspecting the PSU but not 100% sure. I still hope to use this desktop for another 2,3 yrs before i begin a serious overhaul. Seldom use it to game as I got backlog of games to play on PS4.

My desktop setup is as follow:
Intel I5 4440 W/MSI B85-G41
G.Skill DDR 3 16gb kit 1866mhz
Crucial M500 240gb SSD
Nvidia 780GTX FTW Version
Corsair RM650 PSU 80PLUS Gold
ASUS PCE-AC88 wireless card
Fractal Design R4 case

Hope to have some help. I am unable to find the log for the crash despite following the guide to set up a memory dump online.
any good recommendation for the hardware to replace as well?

4 years old rig. Could be due to overheat issue? Check hardware temperature?

You can try reseating the GPU and RAM first in case it is a connection problem.

I had a similar issue with my PC where it will crash and will not start-up again. Just on/off looping. It will start up after an hour or so. I suspected PSU but in the end, It was over-heating due to dead pump. So if you can go into BIOS, check your CPU temperature. The Motherboard will turn itself off if CPU temperature is too high and will not turn on again until it is cooled down for an hour or so.

this is very similar to the problem i am facing. how did you solve this?

seems like overheating might be the root cause. the temperature is like 57 deg C for the CPU and 40 deg C for the system. Fan speed around 1700rpm. the temperature and fanspeed seem to be stable for now. this is after 1 hr of switching off.

You should be looking at load temperature, not idle.

57C at idle worries me.

You can stress test your system using AIDA64's included System Stability Test under Tools.

It will show CPU temperature and have a log even if PC shutsdown.

Also, try cleaning your PC. Replace Thermal Paste if you wish...

My solution was to replace the heatsink since my liquid cooler pump died. Your CPU cooler fan seems to be working but not cooling well. Might be too much dust or thermal paste between CPU and Heatsink has dried out.

Using the AIDA64 system stability test, the CPU temperature is really way too high! it reaches 90 deg C.

Guess I need to open the desktop up and dust it again. I only dust it 6 months ago.

No idea how to apply thermal paste but i guess youtube can help with that.

Likely the thermal paste hardened after 4 years. May need IPA to clean off before apply fresh paste.
