Hi, I'm here in this forum.

I have a trouble with my computer. When I trying to ran a program (ex. browsing with firefox/chrome) and some time later the computer has restarts itself. Not shutdown.

So I decided to check my temperature with HWMonitor. Can you check the temperature that's whether normal or not?

I will upload the screenshot. But I also check on task manager performance and get the results :


The results from task manager I got when running a program (ex. firefox), and after that the cpu usage is normal.

That's my trouble, I hope you'll help me.

Sincerely
Garyu73

Welcome to Tom's Hardware Forums!

Before getting too involved changing settings, plug in the computer into a direct wall outlet and run it. Check performance.

Computers reboot for many reasons heat usually being the number 1 but it could be something else.

Did you change anything before this started happening?

What stress test have your tried, Furmark for the GPU, Prime95 for the CPU, Chkdsk for the Harddrive and Memtest86 for the RAM?

This has been happening to me as well. Question for you: whenever it restarts, do your fans or anything turn off at all? Mine do not, and I don't think that it's a power supply issue since they would probably turn off if it was.

Could be a lot of things, but for starters try these options:

1. Run memtest86 for at least 3 passes, it will more likely show any ram problems
2. Run prime95 to check your processors stability
3. Check your temps with a program like cpu temp
4. re wire your rig, sometimes it's just a wiring problem
5. Try booting into save mode, to see if it's software related.

Hope it helps

The 12 Volt output of the PSU is very much out of spec; too low. It should never go below 11.4 Volts under load.

Replace this PSU before it damages other parts.
