PC randomly restarts

[Mattejoo]

Hey

So when my PC is under heavy stress (especially gaming) it starts to give some electrical sound (not beeping, I don’t know how to describe the sound) and then freezes, BSOD and restarts. Sometimes when it restarts, it starts a disk repair. This started a couple of weeks ago and I haven’t found any clue what causes this.

Any idea what causes this?

Hi,

What power supply does your computer have and what are your computer specs?

Is this a pre-built computer or a custom built system?

Are you overclocking any components?

[Mattejoo]

I have an HKC 650W PSU which is almost 5 years old

My specs are:
Windows 10 64 bit
Motherboard: ASUS F1A55-V
CPU: AMD Athlon II X4 631 2.6GHz
GPU: Gigabyte Nvidia GTX 560 Ti OC
RAM: NANYA 2GB PC3-10600U DDR3 x4
Storage: Seagate 500Gb HDD

A PC technician built this computer about 5 years ago, and I didn’t change anything in it.
No, I don’t overclock anything.

Do you still need assistance?

[Mattejoo]

Yes, I still need it. Now my PC freezes, and restarts in idle.

Ok let’s get more help.

I’d be stripping it down firstly, that’ll allow inspection and cleaning of all parts.
reassemble everything on a piece of cardboard on the table or floor and start it up.
if the same issue occurs, I’d then be looking at backing up all my data and loading a fresh copy of Win10.
you could try a repair install of Win10 (keeping your programs and data) but at 5 years old, it wouldn’t hurt nuking it from orbit and starting afresh with everything.

then, from the clean slate state, run the rig without any additional software for a few days and see if the issue occurs.
if not, add one program at a time and test it out again.
during all that, if it’s hardware, it’ll show itself - like failing hard drive.
or if it’s software, you’ll know it the last program installed when it starts crashing again.
