Question

Strange situation win 8.1 Blue screens

Apr 4, 2018 6:45AM PDT

Hello,

Yesterday I noted that all my video players have only top left corner visible (rest was green), I installed K like codecs Mega version. From that time my laptop started to restart randomly or gave blue screens. Uninstalling the codecs did not help. First blue screen: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (dxgmm1.sys). I decided to back-up the system, but it did not change much. From time to time I get resets or blue screens (IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGED_AREA) and idk what to do with this. I have made antivirus scans (MBAM, Avast, etc.) and they've found nothing.

System specs:

Toshiba K56C (laptop)
Intel Core i5-3317U CPU 1.70 GHz
Ram: 8gb (2x4gb, one of them bought month ago)
System: Win 8.1
Graphic card: GeForce GT 740M

This sounds like the old hardware acceleration issue.

Since it's bluescreens on video playback this sounds like the old hardware acceleration issue. I can't quite figure out what video player you are using but VLC PLAYER does not use CODECs and the hardware acceleration setting varies with the player or web browser.

Since all this has long discussions I will shortchange you here. It is video driver related and on some machines was never fixed. Really irks folk that rediscover this area. I continue to disable video hardware acceleration and a few push to fix this and encounter sadness.

Restarts at start

Ok so, the only moment when it may restart is early after start (when all the icons show up etc (Kernel-power id 41 category 63). I guess sth is wrong maybe with startup processes?

If it does it cold.

Then it sounds like old motherboard issue or a subpar PSU. The reason for this is electrolytic capacitor aging. As they get old they lose capacity and you see symptoms like this but they clear up as the machine warms up.

This can also extend into symptoms where the computer will tap the PSU and motherboard hard and BSOD. Let's hear make, model and age for both PSU and motherboard.

Yeah same make, a bit newer model. I think the whole problem is gone for now. Last time it restarted was yesterday morning shortly after turning it on. Now it works good.

Problem solved, bad RAM card that I bought 2 months ago. One interesing thing is that what did it had to do with installing codecs? or is it just random "coincidence" that after installing them my RAM felt sick? Silly
