Windows 7: Black screen crash; DSL modem crash

Black screen crash; DSL modem crash


This morning (11.26.14, 8:50ish) I had nothing running more than usual (chrome, onenote, word) on my desktop. I was in my other room turning on my laptop but it would not find my wireless network. I went to my desktop and found that the monitor turned itself off (that's normal) but moving the mouse and pressing the spacebar would not wake the monitor up. The desktop power light was on and the monitor light was on. I then looked at the DSL modem and saw the power light was red. So I unplug it and waited 20 seconds; plugged it back in and the desktop rebooted.

Could a power fault on the modem affect the desktop like that?

I checked the event log viewer and the closest I can find is this:

Source: Service Control Manager:
The Microsoft Network Inspection System service depends on the Microsoft Malware Protection Driver service which failed to start because of the following error:
A device attached to the system is not functioning.

Attached is the win 7 utility info you offer.

Temp Monitoring

Check for heating issues using Speccy or HWMonitor.

Run Disk Check on your Hard Drive for file system errors and bad sectors on it.

 Hard Drive Diagnostics

  • Double click and open my computer.
  • Right click on desired drive and hit properties.
  • Click on tools tab and Check now.

Read complete instructions on the tutorial: Disk Check

Other Tests:

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

Errors are sometimes found after 8 passes.

Memtest should be done overnight.

Thanks for the options. Didn't think about temperature concerns. Right now (after being off all day) all the temps are in the low 30 Celsius.
Next I'll run the disk check.

Sfc scan is clean. Disk check was fine. Heat is doing well thus far. Doubt it is any application conflict (powering down the dsl?) because I have added no new background apps in months. This rig is 1.5 years old with carefully built up apps to avoid such problems. Only thing left is the mem test and more hdd test for my seagate.

The crash was not treated as a normal crash as bluescreenview program did not find a dump file on C:/.

I still suspect some dsl driver error as I vaguely recall this problem once before a year or more ago.

5 passes (and 12 hours later), memory looks good. Did 3 passes the night before. Since I cannot replicate this error, any software troubleshooting by halves is not worth it at this point.

Oh, well.
