[SOLVED] PC randomly freezes / restarts

[andromedaftw]

Hi, i am having this problem for many years i cant still solve it. Before, my pc freezes with pixelated screen. Now its only freezing with static display (when gaming), i tried to update bios and reseat the ram and reformatted my PC after a week it doesnt freeze but yesterday and just now it doesnt freeze but randomly restarts. I already tried replacing my PSU, Temps were fine GPU is 60-62C while gaming, CPU is 45-55C while gaming, crystaldiskinfo says that my ssd is 100% good and also for the hdd. Im suspecting that the problem is ram or motherboard, but i already tried win10 built in mem-test (extended veersion) and it says that no problems/errors were found. i only got 1 stick of ram and no spares so i cant really troubleshoot it 🙁

Specs:
Intel i7 6700
Asus H110M-D
Corsair LPX 8GB DDR4 2400 Mhz
Asus Strix Gtx 1050 Ti 4GB
FSP Hydro Gold 600W
Samsung 850 250GB SSD
WD Blue 1TB 7200 RPM

Hi there.

I'd check your motherboard for any bulging capacitors. This might indicate failing/overworked components on your motherboard.
The VRM on your motherboard is also very poor and has no heat spreaders above the VRM. Even though your CPU's temperatures are fine, it's hard to see what's happening with everything else on the board without the right tools, but any kind of disfiguration should tell you what you need to know.
I'm assuming by your CPU/GPU temps that you're case is well ventilated, so your motherboard may not be overheating at all, but it's the weak point of your system at a glance, so it's worth taking a look.

You mentioned that you've re-seated your RAM already, but did you also try each RAM slot on your motherboard 1 by 1 while gaming?

Failing all of this, you'll need to find some parts to borrow to test things out with somehow, or take it to a shop that has the resources to do so for you.

I think you're right in saying the RAM or motherboard is the issue, however there's also the possibility of the GPU having problems under load. Maybe test this by trying games of varying stress on the GPU and CPU.

Hi there, sorry for the late reply. I already upgraded to a new pc since my old psu died and im frustated with the screen freeze but im still curious about the error before. When i removed the cpu from the socket, i noticed that there's like a very little tiny color gray something in the motherboard socket looks like a thermal compound to me (not bent pins). Can that be the problem? By the way i believe that the motherboard VRM is not overheating as before i'm always checking all the temps using HWMonitor (not that superior to HWinfo but fine). Last thing, one thing that i noticed before is that when i accidentally dropped the side panel to the table besides pc, the pc freezes again which i believe that vibration causes loose into the motherboard like RAM? I'm really trying to fix the problem for 3 years so even i already upgraded to a new pc i would still like to know whats the problem. Thanks

Thermal compound is conductive material, so having any in the pin socket or on the CPU pins can/will cause problems. I've only ever seen this manifest wherein the PC failed to show a display (failure to POST), but it could well cause issues in other scenarios, such as yours.

Generally, system freezing along with screen pixelation occurs when a CPU overheats, such as when a CPU cooler hasn't been seated properly. Since your temps are fine (as stated in your original post), I guessed it could be the VRMs that are overheating. Also, software-based temperature readings aren't always correct, particularly when it comes to VRM temperatures. Just something to keep in mind.
Faulty RAM and/or motherboard memory slots can also cause display issues, so it was worth exploring.
Even though vibrations are usually only a threat to mechanical components (such as spinning hard-drives), shifting of any component could briefly affect contact with the motherboard and cause freezing.

I'm willing to bet on the thermal compound as the most likely cause of the issue. Do your best to carefully remove any trace of it from any gold contacts/pins using a toothpick & cotton swabs. If the compound is dry and stubborn to remove, 100% isopropyl/rubbing alcohol or CRC contact cleaner will help break the compound down and won't leave a residue.

I'm glad you're still curious about the issue! Hopefully we can get to the bottom of it!

Thanks man, i can't send the pic of the socket here but i think i know enough. Yeah maybe its because of that but i dont really have idea how the thermal paste get there. Thank you for all your help!
