My sister-in-law Ann has been having issues since April. The USB connectors would become intermittent, i.e., not working all the time. She had a battery in her Dell inspiron 1501, which came with the computer five years ago when she got it. I took it out at one point when I found the battery didn't work.Later battery seemed to work somewhat. I.E., the machine would run with it, when not plugged in. I put it back in. The battery made it hard to shut the machine off. When I took it out and put it in my inspiron, it caused blue screen and HSX_CNXT.sys finding in MY INSPIRON 1501. Removed it

I have a Dell Latitude 131L. When I shut the screen and then open it it goes blue screen and gives a message of damaged driver hsx_cntx.sys. It happens every single time.

Yes. My Dell E1505 Blue screens every once and a while. I thought It was overheating but then I saw the HSX_CNXT.SYS in the error log. Maybe disabling the Modem will help. I have yet to find a solution. Ran virus scan, malwarebytes, and every otther scan I could think of. I may reformat and reinstall Windows 7.

Best practices for resolving HSX_CNXT issues

A clean and tidy computer is the key requirement for avoiding problems with HSX_CNXT. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the HSX_CNXT.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
