This thread’s follow-up from (moving off the problematic dial‑up path) already points to the most likely cause: a kernel‑level failure tied to the modem or its driver. was right to suggest malware as a general troubleshooting step, and and were correct to focus on the OS and the disconnect method — both lines of inquiry matter when a disconnect consistently triggers a reboot.

Practical steps to diagnose the root cause

  1. Turn off automatic restart so you can see a Blue Screen message: Right‑click My Computer → Properties → Advanced → Startup and Recovery → Settings → uncheck “Automatically restart.”
  2. Reproduce the problem and note any STOP code or driver filename shown on the BSOD.
  3. Check Event Viewer (eventvwr.msc) for System errors around the time of the reboot and look for unexpected shutdown events.
  4. Look for crash dumps in C:\Windows\Minidump. If present, analyze them with a tool such as BlueScreenView or WinDbg to identify a failing driver.

Isolation and fixes to try

  • In Device Manager disable or uninstall the modem driver and test: if the system stops restarting, the driver is the culprit.
  • Update the modem driver from the vendor; if updated drivers are not available (common with older “softmodems”), replace the device with a known hardware modem (external USB or a router) or keep using a non‑modem connection as a workaround.
  • If no dump is produced, set Windows to write a small memory dump (Startup and Recovery settings) so future failures are recorded. Also test in Safe Mode or perform a clean boot to rule out third‑party software.

Notes and cautions
Back up important data before changing drivers or hardware. Scanning for malware remains a low‑cost, sensible check (as suggested), but given ’s outcome, a faulty modem/driver is the primary suspect.

Sounds like a virus/adware issue. Scan for both and see if that resolves the issue. If you need antivirus, you can use Avast. If you need spyware removal, use malwarebytes antimalware. Both apps are free.

There are several reasons why a computer restarts.

Which Operating System are you using?

I appoligise for the late replies from me, I convinced her to get a wireless connection and ditch that dreaded dial up, problem solved(sort of), I'm sure it is still there just not in use, I think it was the 56k internal modem. thank you all for your rapid response
