Why does my computer randomly freeze?

Question

Iron

Sometimes I encounter the following problem: the computer freezes, artifacts appear on the screen (see video ). You can still move the mouse for a couple of seconds, then the cursor stops responding. There is no clear dependence on the programs used. This can happen a couple of times a week, and then do not disturb for six months. The system (Win10 first HOME, now PRO licensed) has already been reinstalled many times, the system SSD, RAM, power supply, processor have changed.
Now the configuration is as follows:

look

• Тип ЦП QuadCore Intel Core i7-4770K, 3500 MHz (35 x 100)
  
• Системная плата Asus H87-Pro (3 PCI, 2 PCI-E x1, 2 PCI-E x16, 4 DDR3 DIMM, Audio, Video, Gigabit LAN)
  
• Чипсет системной платы Intel Lynx Point H87, Intel Haswell
  
• Системная память 12226 МБ (DDR3 SDRAM)
  
• DIMM1: Kllisre KRE-D3U1600M/8G 8 ГБ DDR3-1600 DDR3 SDRAM (11-11-11-28 @ 800 МГц)
  
• DIMM3: Silicon Power DCLT4GN128S 4 ГБ DDR3-1600 DDR3 SDRAM (11-11-11-28 @ 800 МГц)
  
• Видеоадаптер Asus GTX750TI-DF Series
  

If necessary, I can send the AIDA64 report.

Answer 1

A classic dump (soldering contacts from overheating) of memory chips or partially a processor on a video card. Warming up in an oven can restore the contacts to normal and may work normally for several more months or years. Well, or just hand it over to the service for reballing the memory chips and the video card processor itself.

Answer 2

disassemble the computer (and the power supply does not hurt), clean it from dust, clean all the connectors - assemble.
look at electrolytes.
such a feeling of non-contact somewhere or oxide.

Answer 3

I have something similar with my computer.
I just noticed a feature, I just sit in the internet, I watch video music, etc. or just go to the sites. (the game was not affected in any way)
- that he just didn’t do it. and went over the computer and took 4 times to the masters. the problem was 6 years in a row. "Windows has been the same all this time" - and then recently "it sounds stupid but still" I changed Windows ... and the problem seemed to be solved ..
before that, my friends advised me to change Windows 100 times, I refused because I was wondering what type of thing Windows has to do with it, and if there is some kind of problem with the computer, then changing Windows is not an option, obviously the problem is in another virus, etc. yeah i was lazy..
Well, this helped me. although who knows, maybe I went through it for the last time, changed the thermocouple on the bridge and the video card, and all that stuff can also affect it.
