Random freezes yet all the tests are okay

[Zeinone]

Hi LTT!

 

Firstly I'll describe my problem.

I've reinstalled windows a week ago, a clean wipe using the built in 'windows reset' because i forgot my windows key. Nevertheless, a clean reinstall, blank discs, blank everything. Took me a day or two to reinstall all my necessary software and in the last day or two i somehow got random freezes. I narrowed the source to any video playing, for some reason that makes my laptop freeze, followed by a sound 'freeze' (continuous single frequency until a stop), regardless of the platform (youtube, netflix, local .mp4's...) that can only be 'fixed' by a hard shutdown (holding the power button).
So, after 3-4 freezes made by playing videos, i went to Event Viewer and saw Nvidia making a problem, reinstalled geforce experience, GPU drivers, worked fine for a few hours then again, freezes.

Today, same thing, went on youtube, 2-3 minutes of video playing later, freeze. Went to event viewer after a hard shutdown, nothing, no Critical and or Errors (despite error 41 that it experienced an unexpected shutdown.

Went to safe mode, played videos, everything works perfectly (I am typing from safe mode right now). Ran Dell Diagnostics, ran Dell's stress tests using 'SupportAssist', and performed memtest. All the tests were okay, no errors whatsoever.  Opened up an article online with a video playing in the background, and there you have it, it froze again, although everything is working fine.

I also ran MalwareBytes to check for viruses, everything's clean.

 

Spec:

Dell G7 7588 (Laptop)

i7 8750H

GTX 1050ti 4GB

16GB RAM

256GB SSD

1TB HDD

 

What I've tried:

• Diagnostics from the boot menu (cca 3 hours of waiting, no errors found)
• Dell's Support Assist analysis (stress test, drives check, optimization, everything basically)
• Checking for Driver updates on Device Manager, all up to date
• Windows update (currently being 'up to date', Windows 10 Home 64-bit (10.0, build 18363) according to dxdiag)
• Booting in safe mode (no freezes whatsoever)
• Windows memory diagnostic (no errors again)
• Checking Event Viewer (nothing helpful as said above)
• MalwareBytes scan (no viruses)

 

So far I think that some kind of software is causing this issue, correct me if I'm wrong, since all hardware tests came positive. The first few days after the OS reinstall it all worked normally, and all of a sudden it began to freeze with the only correlation I've found is playing videos, since nothing else (at least what I've found) apparently makes the PC freeze.

Go to YouTube, pick a video, right click when it starts playing and either turn off, or on Hardware Acceleration

 

See if that helps.

Download HWMonitor and see how high your temps are when the freezing occurs. Sounds like it could be overheating and causing thermal throttling.

Since it froze, I couldn’t printscreen, but here’s a speedfan picture of the temps (hwmonitor doesn’t see my cpu temps for some reason)

Does it have any newer Bios or chipset versions available? Check the manufacturer website for the laptop and check for updates there. Device manager is sometimes out of date or can throw out completely wrong updates.
