CPU Intel i5 8600K
Motherboard MSI z370 Gaming Plus
RAM Corsair 2x8GB DDR4 2666mhz
GPU MSI GTX 1050Ti 4GB OC
PSU Sentey XPP725HS-S (725W)
Case Sentey BX1-4285
HDD Toshiba 1TB
SDD Kingston 240GB (I have W10 installed here).

I bought this custom-build PC a few weeks ago, and everything was working just fine. Yesterday I was playing PUBG when the game suddenly stopped working. I thought this could be normal, but the game was not starting anymore, and then I realized I could not run any game at all: it always showed up the "*game* has stopped working..." window. Then other crazy things started happening, like Firefox, Chrome and even Windows Explorer crashing as soon as I opened them; And also everytime I clicked on an icon from the desktop, it "painted" it (picture below for better understanding).

I did my research, and in similar cases people recommended testing the RAM. I used the Windows Memory Diagnostic tool. The results were "no hardware error", but to be sure I booted the PC with just one stick: I took out one of the sticks, booted PC (everything was working the same as before), took out that stick, put in the other one, and everything was just the same. So, the only chance with a RAM problem is that both sticks are not working fine.

Then, I took out the GPU. Everything was as bad as before, so GPU wasn't the problem.

Next thing I could do, was reinstalling Windows. I did that, twice. The first time, it pretended to install correctly, but Windows was working WAY too slow. Icons in the taskbar were not showing up, the clock from the taskbar was also missing, IE was taking like 30 seconds to open. It was unbearable, so I had two suppositions: 1. The Windows I installed now, was not a good one so maybe I should install the one from the first time again. 2. It's just the same problem than before, so the problem was not Windows at all.

So, I reinstalled windows for the second time. And then again, the computer was extremely slow, and the story from the first reinstalling repeats. BUT, then something even worse happened: I resetted it, but it never booted Windows. Nothing was showing up, not even the Motherboard screen ("splash" screen). I gave up for the day.

Now I am here, about to make a few more tests. I tried booting it once more before doing something else, and Windows booted! it is so weird. What I am going to do now is to reinstall Windows but in the HDD, as maybe the SDD is the one making trouble.

I wanted to know if anyone experienced something similar to this, or if anybody can give me ideas of what to do to detect which component is the one failing. Can it be the PSU? Or just a Mother/SSD thing?

Sorry for my English if I misspelled!

Well here I am just 4 months later, fortunately with my problem solved. It actually was the CPU, for me a bit unbelievable. So many tests thinking of the mobo and RAM, and ended up replacing the processor and BOOM no more problems. Of course my CPU had warranty, so I contacted Intel support. They told me to send the faulty CPU to USA (Kentucky), and yesterday I received an email that said they have already sent a new product back here to Argentina. So in a few days I will be using, finally, my PC. I don't have to pay anything since they pay UPS the shipping and everything.

Just wanted to give this thread a conclusion for anyone with a similar problem that finds this post. Thank you all.

At first glance, the artifacts definitely seem like the fault of the graphics card... when you took out the GPU, did you plug the monitor into the motherboard port? Maybe try replacing the cable, though I doubt it can cause such serious problems.

The next culprit could be the power supply. And its quite probable, since that's a horrible power supply. Before anything else, I suggest getting a proper power supply, like the Corsair CX450 or SeaSonic S12II 520 W. Power supply failure can cause all sorts of funny things, so get that trash out of your system first.

Well.....as I was reading.....the PSU and/or the motherboard came to mind as the culprit(s). I don't think a bad SSD would make Windows run slow. I also don't think it would cause the display problem.

I would be checking the voltages on the PSU if you can do that....or swap one in. That's the easiest thing at this point.

Windows Memory Diagnostic is not the best tool to use. I'd strongly recommend MemTest: https://www.memtest86.com/

Also, Kingston has it's own SSD utility. You can download it here: https://www.kingston.com/us/support/technical/ssdmanager

Otherwise you could use CrystalDiskInfo: https://osdn.net/projects/crystaldiskinfo/releases/
or HDTune: http://www.hdtune.com/

They'll let you know how your drive's health is doing(sector errors, temperature, etc)

Well, I will update you how things are going on with this little nightmare.
Thank you for your answers, they did help me. So I tested the following:
- Ran Kingston SSD manager: nothing wrong, ssd seems to be healthy.
- Ran Memtest86. Got several errors, and by several I mean 1900 errors (although I always got different amount of errors: the first time I ran it, 290, the second 317, and finally +1900) in test 6 ("block move"). Did my research, very likely RAM is bad.
- Still had to change PSU, luckily I had one from the old computer that has been working perfectly for 3 years. Did that, and reinstalled Windows, once again. Windows, at least at the beginning, is working fine. Nothing compared to the last time I installed it. So, my thoughts were: OK, maybe memtest was giving me so many errors because PSU was faulty and, I don't know, maybe RAM was receiving more or less voltage than needed. So, with Windows working fine, I Ran Memtest86. First pass: 0 errors. I thought it was over and the only thing I had to do was going and buying a good PSU. 2nd pass: 2 errors. 3rd pass: 50 errors. And it went on.
- Frustrated, I Ran memtest86 with one stick, then with another, changed slots, everytime showed me a good amount of errors.

I don't know what to think, maybe changing the PSU and Windows working fine was just a coincidence, and with RAM faulty, sooner or later it will give me blue screens and the same problem as before. What do you think? Maybe the last test I could do is using the RAM on another PC, but I will have to look for someone with DDR4 mobo.

Not sure what's wrong either but I can at least offer something. Go to your BIOS and look to its health section. It will have your voltages including the +12V rail which "feeds" the GFX card.

HwInfo can also show you that number. Both the BIOS and HwInfo shows it at 12.320V. 12.0-12.5V is the safety zone.
