Update or install proper video drivers.

Most of the above causes of flickering can be fixed by using methods below. This can be caused by either a low refresh rate, incompatible apps or corrupt or bad display drivers. When the refresh process does not happen as fast and smooth that’s when the human eye detects the flicker and this can lead to interruption in the work flow especially if you deal with graphic intense work. Normally the screen redraws itself so fast that you cannot notice it as it happens and you just experience a smooth view of the refresh result. This is when you see the laptop screen redraw itself per second. What causes the dell laptop screen flickering?ĭell laptop screen flicker occurs when you are able to see the screen refreshing.

Also try apply pressure on distorted area or were lines appear and see if there is any change. A quick check will be to see if moving the laptop screen has any effect on the flickering. For me this is easy but for many it is not and that is I would re-flow the solder joints (In fact for me I would have done that when I first had it stripped down).It might be a surprise that you can sometimes fix it quickly. If it crashes then it could be a motherboard issue. Again, if it does not crash in a month then it will be a Windows issue and perhaps a reinstall of Windows will cure that. I would then probably dual boot it with a Linux Distro and if the company tasks allows it work in Linux.

If the fault reappears then it could be motherboard or Windows itself. If the fault does not reappear in a month, consider it cured. Boot it back into Windows and check that all is still well and it should be.

(NB You or someone has recently changed that and it could be the cause.) After reassembling, I would then: check CPU temp again use a live Ubuntu Distro to check SMART values of SSD and as the Ubuntu Distro starts you can select a RAM check and you can leave it running overnight. If it where mine I would check the CPU temp in UEFI/BIOS and then strip it down to inspect motherboard for any visual issues, clean filters, re-seat CPU with new thermal paste, re-seat RAM, remake connections to SSD, maybe change CMOS battery, etc. If not and the company are OK for you to tackle it and you feel that you want to then it is a job of eliminating all possibilities. I see that it is a company laptop and maybe it is still in warranty and for that you need to check with your company before you take it apart and in any event if it is in warranty let Dell sort it out. I suspect that unless that dump file catches anything you will always wonder what is causing the crash.
