blue screen on start-up and running (on) for hours

[jshermantank]

I have been having a blue screen for several months now. The error message are dxgmm2.exe, win32 k bse.sys, memory management window-10, system service exception, fault page non page, critical process died, register error and oxc000021a, all at different times and most times they are consecutive, but not all at one time. I have ran a  extensive diagnostic test and they all passed. Deleted cookies, temp files, scan for viruses and malware scan with no problems found. Sometimes the problem would start when I start my computer and after about 8 blue screen start up, my computer would start up and operate ok. And then other times the computer can be on all day and then a blue screen. After several times it will start working ok again. My question is, is it a hardware problem or should I just do a full reinstallation. I don't want to buy a new tower if I don't have to, but I have already been looking at new hp towers.

Bluescreen failures (i.e., BSODs) are notoriously difficult to diagnose and to fix -- far beyond what WE typically can do in THIS self-help Community.

You have a couple of different options to chose from ...

--------------------

The first is that of specialized forums where where folks have vast experience troubleshooting, diagnosing, and suggesting repairs for BSODs. These are available depending on the OS involved, as follows:

The community Win10 forums has a section devoted to diagnosing BSODs. So, your best bet would be to post your problem there: https://www.tenforums.com/bsod-crashes-debugging/

--------------------

The second is using free software to examine the logs that BSODs produce. This app is known as bluescreenview and is available from NirSoft, from here: https://www.nirsoft.net/utils/blue_screen_view.html

You will then have to go online to do searches with that information to get further suggestions about what to do.

Good Luck
