M17x R4 random freezes

Hello

I have noticed quite strange issue with my laptop. This happened only twice so far since i have bought it. System freezed during doing nothing at all. First time it freezes with white screen and another time there was blue screen (not bsod) with black vertical lines on lcd. In both situation pc wasn't responding at all and i had to press power button for couple seconds to turn off pc. System is not overheating for sure because temps are ok. Epsa passed but during pc checkup in game test program couldn't access gpu memory. I have this laptop since july and everything was working fine till now. Couple days ago i did clean fresh install and installed newest beta drivers for 7970m (12.9) so i supposed there might be some issue with it. Problem is quite rare and to be honest I never saw it before on my previous machines. Any advice?

 

When did you have the problems? Since you got it or from the new drivers? Also, could be bad RAM or GPU if happening since start v

 

I have noticed this issue after installing drivers directly from amd site. I bought this pc in july but after couple days i did clean os installation and i was using only gpu drivers from dell site. Pc was working fine until now. First time system freezed with white screen on 12.8 and after couple days when 12.9 was released it crashed with blue screen and black lines. I can download stock drivers from dell site again but I think it might be hardware failure. I dont know if this can be related with this issue but i have noticed that when i set the lid in angle less than 60 degrees whole screen is covered with thin black vertical lines not usual for lcd panels because i checked couple other laptops and didnt notice this lines. Also i did a test and took a print screen from my desktop and lines werent visible on that pictures on other pc. Lines on lcd are present from the begining

 

Lines on the LCD are signs of a defective LCD, call up Alienware and get the panel replaced.

 

You can run the LCD BIST utility to check if your screen is broken.

This test will run outside of windows, that way GPU or drivers won't affect the outcome of the test.

 

During bist, in bios image looks ok. I noticed that when im playing with brightness/contrast lines are changing (fyi lines are present on def settings). They are mostly visible on dark backgrounds. On Intel Gpu image looks ok as well. I realized that all me freezes happened during browsing pages via firefox and using flash apps but im not sure if there might be some connection between it.

 

It could have something to do with the driver as it started showing up after the clean install.

Try to do a clean video driver installation

 

Already did, adjusting brightness/contrast helps a lot but it doesn't solve the issue completely. It doesn't bother me so much as long as its not a hardware failure.
