My PC has started freezing with a green screen, then either restarting after about a minute or showing a black screen and rebooting immediately. The first time, it stayed frozen on the green screen for more than three minutes, so I had to hold the power button to shut it down. I've since unplugged and reconnected the power and HDMI cables and reinstalled the drivers. The crashes have happened while verifying files, compiling shaders, and once during a demanding game that used around 14 GB of VRAM. Is it safe to test the PC again, or could another crash damage the hardware?

It’s generally more accurate to say that a hardware or stability problem causes crashes, rather than crashes damaging the hardware. Random freezes can come from faulty RAM, graphics drivers, overheating, power delivery, or the GPU itself. Run a memory test, monitor temperatures, check system logs, and test the components one at a time instead of repeatedly launching demanding games.
You can probably power it on for troubleshooting, but avoid stress-testing it for long periods until you know what’s wrong. Check that the RAM and graphics card are firmly seated, confirm all power connections, try a clean graphics-driver installation, and watch CPU/GPU temperatures. If possible, test with one RAM stick at a time and run a proper memory diagnostic. Also consider whether your home power cable, outlet, or power supply could be contributing to the problem.
A crash by itself usually won’t physically damage your components, although forcing the system off can potentially corrupt Windows or files. The bigger concern is identifying what’s causing the crashes, especially since they’re happening during demanding tasks.
The shop tested the PC and said it was fine, but after I brought it home it crashed again and started stuttering afterward. I’m not sure what part is causing it.
