Windows 10: Can anybody tell me what's wrong with my computer?

Hello, I bought my computer off Facebook marketplace, so I'm not sure if this is my fault or the builder's but out of the blue one day my computer screen turned to black suddenly, I couldn't turn it off by pressing/holding the power button. My keyboard turned off and couldn't be found even when plugged in, a restart fixed that though. Then it started happening more frequently and so I scanned my C drive for errors on bootup, I got a bsod. Yesterday my screen froze as random red pixels were littered across the screen, then it went back to normal. About an hour later my screen froze and turned into this weird checkerboard pattern. I had to restart the pc this time, left it off overnight. I changed power cables to no avail, and about an hour before typing this, it just cut to a black screen then reset itself. I'd really appreciate some help if possible. It's been cleaned, I swapped hdmi, I plugged my pc into another socket. Now I can't really play anything as it just cuts off. My power supply is 250W, I have 8GB of ram, i5 six cores, windows 10 64 bit and Nividia GTX 670. I have tried to update my graphics drivers but I have the best match apparently.​

Can anybody tell me WHY my computer crash?


Are your crash dumps defaulting to "E:\DUMP"?

For troubleshooting steps I would suggest

1.) If any overclocking has been done, undo it. This is a common source of system instability.

2.) Unplug all non-essential devices from the computer

3.) Test your memory - MemTest86+ - Test RAM Windows 10 BSOD Tutorials this can take a long time and it is best to start it before you go to bed.

4.) Temporarily remove IOBit and Bitdefender, as they install kernel drivers. We'll want to eliminate them as a possible source of instability.

5.) Nvidia just released a new driver version today - I'd suggest updating. NVIDIA

 

Silent boot failure

List your specs out and tell us each step in cleaning you did.

 

New FF - passwords


Hi:

If that setting is already enabled, then I suggest as the next troubleshooting step might be Mozilla Safe Mode (not to be confused with Windows Safe Mode)):

Troubleshoot Firefox issues using Safe Mode | Firefox Help

• Please report back and let us know the outcome, as it will dictate the next steps.
• Also: please tell us what AV/AM/firewall programs are you running on this system?

Thanks,
