Video players' video playback failing after a few minutes

Hi guys, so very recently (a couple of months ago) I built a custom desktop intended for gaming, and every game works great on max settings, youtube and online players work fine. However, when I play either Windows Media Player, or VLC player, strange things start happening. For both players, after a few minutes into the video, the video playback disappears and the player becomes unresponsive (can't access menus, can't fullscreen), however, the sound still plays fine. Though sometimes I can open the player menus, but they're blacked out, furthermore, the desktop taskbar starts glitching (chrome or VLC icon superimposes itself on the windows/start logo), re-positioning the taskbar fixes this. Basically, the WMP and VLC players' video playback glitches out a few minutes into the video, but sound is fine. Can't figure this out for the life of me. I've re-installed both players, re-installed the video driver, downloaded Shark007 codecs, disabled anti-virus, nothing works. Here's some of my specs from Belarc;

Thanks for taking the time to look at my post!

 

Well, just reinstalled the chipset and Nvidia drivers, that didn't help.
However, there are no yellow marks in device manager.
ESET is the only security app I have currently.
Uninstalled Shark, ran Ccleaner, with the latest updates installed.

However, when I tried both Safe Mode and with networking, the video playback was completely fine, not really sure what to make of it. Something might be interfering normally?

Attached is startup log.

Thanks!

 

Since I don't have much in the way of files on C:\ I could always just do a clean install and see if that fixes it, provided we can't figure it out of course.

 

Removing DAEMON tools didn't affect the video in any way.
