Seems like rather popular issue with computers in general, but in my case it's really weird. So I will start with my PC specs:
AMD FX 6300 (was running at 100 MHz OC all the time, but I returned to stock speeds)
Gigabyte 78lmt-s2p rev.5
2x 4GB DDR3 Crucial RAM
Palit GTX 650 Ti 1GB OC (upgraded to) Gigabyte RX 560 4GB
Asus Xonar DG (onboard sound works fine)
Samsung 840 EVO 120GB
Seagate Barracuda 1TB
WB scorpio blue 320GB (laptop HDD, that I got for free)
Fortron FSP700-50ARN 88+ 700W power supply (rebranded Seasonic at lower price)
Hardware bought at the start of 2014, except PSU, SSD, sound card. Those were upgraded later (PSU, SSD in 2015 and sound card in 2017) (I got HDD for free maybe 2016, but it has been used since 2010 or 2011).
My problem:
With GTX 650 Ti I have been playing with GPU BIOS and flashed it a lots on this PC, because I wasn't scared of messing it up anyway as I'm going to upgrade to RX 560. Too bad one time GTA 5 crashed and I instantly suspected graphics card. Too bad it was stable as rock in anything else and after returning to stock BIOS and therefore, stock speeds, GTA 5 has been crashing and sometimes with PC restarting. I wouldn't suspect power supply as it's a quality unit, but I did suspect BIOS settings a bit. Turning off power saving features and CPU turbo mode did nothing. I also wanted to try out Office 95 for some retro feelings and all, but installation had errors and some fonts were malfunctioning. I found solution to this problem myself with some software and font reinstall. Too bad GTA 5 crashing problem remained.
Further fixing:
Malware scan (Malwarebytes software) (found two trojans)
virus scan
registry cleaner and fixer
gpu driver cleaning and installation after upgrade to AMD (still nothing)

chipset driver reinstall
driver finding software
Further adventures:
Turns out that I missed one important bit. I had Doom, which crashed too, but I suspect huge lack of VRAM, too bad getting new card didn't solve that. Also Sleeping Dogs crash at the start (after gpu upgrade). In GTA 5 crashing case error messages are random. Sometimes mentions VRAM problem, sometimes mentions random process being stopped, sometimes just GTA 5 crash, sometimes RX 560 in device manager becomes marked and then after re-enabling it again it works (GPU, not GTA). At this point I don't know is it hardware problem or software. Many other games like Unreal Tournament 2004, Unreal Tournament 99 GOTY, Juiced, GTA 4 work fine and PC survives extensive stress testing (CPU and GPU, haven't tested RAM). Only today I noticed that it crashed at waking up from sleep, but still rebooted. I have been desperate enough to start looking at Windows problem reports and it seems like AMD fuel service and FreemakeUtilsService are crashing often. Once bad_module_info too, but I got this error after one GTA 5 crash. One this PC crashed just at web browsing without much load on CPU. One important detail is that I never get BSODs. I wish I had, to make trouble-shooting easier.
Oh I forgot to mention one more thing. I changed BIOS setting from native IDE to AHCI, but I didn't forget to edit Windows registry for that. I'm not sure how to test this out, but it doesn't seem like a problem causing thing.
Any solutions? Plz no Windows reinstall, I don't really want to redo everything, that's very time consuming and I don't really have many options for backing up.
last note:
I did lots of other things that could potentially fix the problem, that I don't remember anymore. I have been living with this stability problem for almost one month.
