Slow PC performance, out of video memory.

[DonaldClinton10]

Since a few days my PC, which is less than 1 year old, has slow performance and frequently crashes when I try to play games. Sometimes I get an error when playing a youtube video.
The PC also takes pretty long to boot.
My PC SPecs:

CPU: Pentium G4560 dual core 3.5 ghz
GPU: Nvidia GTX 1050 TI with 4GB vram
RAM: 8GB DDR4


Here are the things that I've tried so far (but did not work):
- Disable page filing
- Run antivirus scan and check for malware
- Disable startup programs
- Run windows in safe mode
- Reboot computer
- Close background programs

Please post your full system spec.

Have you installed anything lately? Including Windows updates - which you can check for (Settings>Update & Security>View installed update history)

Last windows update was version 1709, november 2017.
I have not installed anything that's bad.

It's certainly not video memory. Most likely cause is something overheating. That would cause it to go slow (clock down due to excess heat) and sometimes crash (overheated). Check temps of cpu + gpu, if one of them is very hot check fan is still working, and heatsink hasn't come loose.

I just checked and it's about 30-40 celsius for both GPU and CPU so that can't be it.

Well that's the simple answer out. So it could be cpu, gpu, memory, motherboard, psu, hd. Try to narrow it down - do tests to stress different parts of the system:
cpu - run some cpu burn test that doesn't use gpu and doesn't use much memory.
memory - run mem check on it, run cpu test with big memory usage, try running with 1 stick of ram, then swap them over.
gpu- run a gpu burn test.
hd - does it start windows slow? Run some hd tests, check hd smart info.
psu and mb are much harder to diagnose as they typically result in other stuff crashing. I once had a mb slowly die over the course of a year, and it was near impossible to tell that was it (I swapped out half my system before eventually replacing the motherboard at which point everything worked fine again).

Once you think you might have narrowed it down you want to swap out broken stuff and see if that fixes it. If you've got a friend you could ask to borrow their machine and swap out the gpu/memory/psu (well leave psu in their box but plug all the cables into your machine).
