Windows 10: Computer randomly restarts with demanding tasks

Hello everybody

About a week ago I bought a new desktop PC. The problem is that when using the computer for moderately demanding tasks such as gaming, the screens go to black without warning and the PC reboots. In the event viewer there is no indication of any error. There is only a message that states that the computer wasn't turned off properly. The problem occurs about 1-2 hours into the games.

It's important to say that all the settings in the BIOS (which is up to date) are set to default. None of the components are overclocked. It's important to mention that also while gaming, from time to time there are random freezes of a few seconds of all the system, where not even the mouse moves. Only the audio continues normally.

The kind of tasks that cause the reboot of the compute put an average load on the CPU of around 40%, with some peaks in between.

I understand that computers can reboot if the CPU temperature becomes too high, however, it stays at an average of 65 degrees celsius when measured by using the Core Temp application. It never peaks at more than 75 degrees.

All the drivers are up to date, including the GPU ones.

I took the computer to the shop where I built it. However, they were unable to replicate the problem and according to them everything seemed to be fine. However, I can't really trust the competence of those technicians because of some stories that I have heard. The problem is that for the moment I can't really take the computer to some other place beause it would void my warranty.

A few minutes before I decided to write this post I noticed that the USB 3.1 Gen 2 ports of my motherboard (the green ones) seem to be dead. Yesterday they were working fine. Also, I have an audio connector in the green jack of the motherboard. From time to time the computer asks me if I connected a new device there. The connector is firmly connected. Could this be some problem consisting on the system not receiving enough power?

All my system is connected to an APC Pro 1500 UPS, which has a maximum output of 865 W. Also it's important to say that I tested the RAM with the Windows Memory Diagnostic tool included in Windows. It showed no errors.

The specs are the following:

Intel® CPU Core i9-9900K 5.00GHz (1151-v2)
Asus M/B Intel TUF Z370 Plus Gaming (1151-v2)
Asus Video NVIDIA Geforce GTX1660Ti O6GB Dual Fan
Crucial DDR4 16GB 3000MHz Ballistix Sport LT (Red) (2 sticks for a total of 32 GB)
WD Unidad SSD 1TB Sata3 2.5" Blue 3D NAND
Seasonic Power Supply 1000W Focus Plus 80Plus Gold - Full Modular
Corsair WaterCooling Hydro H100X 2018

Also I have Windows 10 Professional 64-bit (which is up to date), as well as three other conventional hard drives of 2, 4 and 5 TB.

Any ideas?
Thanks

Task Switcher randomly gets stuck cycling windows


Good morning!

I am having an issue with the Task Switcher (see image below) activating on its own. It then begins to cycle through the open tasks very rapidly. When this happens I am unable to actually select any of the tasks, nor can I close them out. Windows is essentially frozen at this point and I have to restart.

A few things to note:

• I am running Windows 10 Pro.
• This happens randomly, sometimes weeks between an incident.
• Sometimes it happens while I am not even working at the computer. I've noticed it after returning to my desk.

Any ideas or suggestions would be greatly appreciated!

 

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?
