[SOLVED] PC starts up, normal display, but then suddenly shuts down ?

[sldjmix]

Hello,Move thread
I am having 4th Generation i7-4700 Processer, Intel DH87RL Motherboard, Corsair 8 GB DDR3 RAM.

My PC starts up, normal display, but after like 2-3 minutes it's shuts down. Then after when I'm trying to on it, it's not showing display, sometimes display come but it's scrambled and showing flickering display. I checked my RAM, CPU and it's Heatsink, Power supply Unit, everything is fine. I'm using Integrated Graphics, what do you think i am getting problem bcoz of onboard GPU. GPU heatsink is getting little bit hot. Please anyone can tell me solution for this.

It's probably an overheating symptom.
Your CPU is probably overheating, & Integrated GPU (iGPU) is inside it.
Reapply thermal paste of good quality, good brand don't choose any unknown random brand thermal paste.
Then make sure CPU cooling fan is turning ON.

Make sure all cables are properly connected, nothing is loose.
