Windows 10: My computer restarts randomly when playing a specific videogame.

So My computer shuts down regularly when I play a specific game but not for any other game. There is no warning or error message it just restarts with no warning. I have tried updating drivers, changing in game settings, reinstalling the game and nothing works. I don't believe it is a hardware issue due to the fact that it only happens while playing once specific online game. The game is League of Legends. Processor AMD Ryzen 9 7900X 12-Core Processor 4.70 GHz Installed RAM 32.0 GB 31.1 GB usable Graphics CardL Nvidia GefForce RTX 3080 RTX System type 64-bit operating system,

LAG spikes while playing videogames

My internet starts to really lag randomly whenever I play videogames. My discord is fine, it doesn't seem to be affected by it, only the videogames i'm playing. Even if I stream, nothing happens to the stream, only the videogame lags. It happens constantly, random lag spikes that prevent me from playing alltogether. It's only with a few videogames and my internet is completely fine until I start a game. What could be happening? How do I solve it?

 

Screen Performs a 'Blackout' When Playing Videogames

So, for the past many months now I've infrequently encountered issues with the display blacking out; which is to say that the screen cuts to black, I hear an error message from Windows, and the computer continues to receive input (with no screen output)
evinced by sound tones from keystrokes. The only solution is to then restart the computer.

The causes of the blackouts are arbitrarily specific, and are repeatable. I can perform a very specific action in a specific videogame to cause the blackout, which makes the issue avoidable (which explains why I've waited so long to seek support). For example,
there is a map in an FPS game that takes place in a shopping mall. If I travel to a specific store in the shopping mall, walk to close to a specific spot--all the while looking at it, I get the blackout. This problem has only existed across two games; Destiny
2, and Escape from Tarkov.

Now, with the problem explained, I have taken steps to troubleshoot it.

To rule possible GPU failure, I performed multiple stress tests--benchmarks--without failure; the results indicated the GPU was functioning optimally. I then reinstalled my display drivers multiple times using DDU (Display Driver Uninstaller) to ensure no
trace of the driver remained; there was no change from this. I decided to examine Window's Event Viewer, and every instance of a blackout suggested "dwm.exe" was at fault.

I'm not sure what could cause dwm.exe to fail, or what could be done to resolve the failures.

Any 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?
