Lockup & Horizontal Lines on Dell E6410 Screen
I have a Dell E6410 and of late I have noticed that my system locks up with horizontal lines on my screen. No keys work and I have to hit the power button to shut down and restart.
It's a Core i5 with Intel Graphics running Windows 7 64bit.
It's under Dell cover and they already replaced the screen and motherboard but the problem continues.
I have ran Dell Diagnostics as well which ran without any problems.
I have a screenshot here. Any ideas on what could be causing this?

Almost every entry in your event log seems to be this:

An error occurred while dispatching a duplicated socket: this handle is now leaked in the process.

For more information about the error, either turn on IncludeExceptionDetailInFaults (either from CallbackBehaviorAttribute or from the <clientDebug> configuration behavior) on the client in order to send the exception information back to the server, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the client trace logs.

In the mean time I am asking for some more help.

Since the display and motherboard have been replaced already, it does not appears to be a 'hardware issue'. Would like to know if the back cover was also replaced along with the LCD screen. The back cover kit comprises of various cables that connect the screen to the motherboard. Though a remote possibility, I am suspecting one of the cables as the point of failure, rather than the display or the motherboard itself.
Refer to the 'back cover image' to see if you can recollect this part being replaced when the repair took place:
E6410 is built with both variants of motherboard (Integrated or Discrete); please share details of the system that you have.
To isolate 'hardware' as the possible cause of failure, would request you to perform the following steps and capture the findings:
- Try using the notebook with an external display (monitor) and see if the issue persists.
- Allow the system to stay in 'BIOS environment' for some time to check if the 'display problem' is observed there also. To enter BIOS, restart the system and repeatedly tap 'F2 key' at the 'Dell splash screen'; let the notebook stay there to check results.
- Also use the system in 'Safe mode' to see if the issue duplicates itself.
Based on these observations, we are likely to eliminate 'hardware' as the possible cause of failure.
Also confirm if Windows is configured to record the 'crash dump data'. You may want to re-check with the instructions in this tutorial: Dump Files - Configure Windows to Create on BSOD
Also refer to this tutorial if required: Blue Screen of Death (BSOD) Posting Instructions
As 'Arc' stated, please don't worry at all. We will investigate the matter on priority and hopefully, should be able to find the root cause.
Do reply with the findings; will take it forward from there.

Thank you for your reply. I hadn't realized that there was reply to my post. After you pointed out I think you are right about the back panel.
Recently my back panel and LCD was replaced due to a different problem (there were particles stuck in my LCD) I noticed the horizontal line problem only after that so I am guessing as you suggested it is a cable issue.
I will speak to Dell support and keep you updated.

Thank you for the reply.
If the back panel/LCD were replaced recently, there is a strong likelihood of either a loose physical connection between the cable(s) and the board; or a damaged cable/connector. The fact becomes even more probable as you began facing the 'display issues' only after the parts were replaced.
Do reply if you need any further assistance; would be glad to assist.
