Description of crash

Computer monitor cuts signal and the monitors display the "no signal detected sign" sound cuts, lights in side of computer never flicker and it appears to still be running as normal. I need to hold the power button for 10 seconds to shut it off. Since In mid/late 2014 my computer started crashing while gaming. It happened every couple of dota/csgo games to give you an idea of frequency. I took my computer to my uncle's house and he looked at it and replaced my graphics card, one of my two fans, and added two 4gb sticks of ram. The problem persisted however the problem's severity varied and I could go multiple weeks with no crashes if I avoided games that crashed.

Since upgrading my PCU, motherboard and to windows 10, a new thing happened. After crashing my sound came back, and I was able to talk to my friends on team speak. This does not occur every crash, but it has happened multiple times. I tried alt+f4ing from games, stopping streams, but my keyboard didn't work, num lock/scroll lock lights stick in whatever spot they were at time of crash.

A list of what crashes and doesn't:

CSGO, DOTA2, Path of Exile, Far Cry 4, Diablo 3, Borderlands 2 all crash, differing severities. Path of Exile gave me the only way to reproduce the crash by initiating the Piety fight which caused crashes probably 50% of the time, while playing normally very rarely crashed.
Runescape, Stardew Valley and Rocket League don't crash, or at least I don't remember them crashing. Since upgrading my mobo/processor and to windows 10 Piety no longer crashes regularly and I have not found any way to reproduce it easily.
Recent timeline

In 2015 I just kind of let the problem go as I could play counter strike more or less crashless.

In 2016 I have replaced, in order of being replaced, my power supply, my hard drive and then my processor/processor fan and motherboard at the same time while upgrading to windows 10 as well. I tried swapping my ram sticks in and out, trying to see if any were faulty but no combination of the 4 sticks changed anything. I unplugged the one fan I had left from original build and the temperatures/crashes remained unchanged.

The only thing I have left from when the problem started is the case, one fan which is unplugged, 2 sticks of 4gb ram, and the cdrom drive.


Things I have tried to find problems.

I have reformatted my computer three times since this problem started. Once at the start, sometime in 2015, and more recently sometime in february. Upgraded to Windows 10 start of April, started from new then as well.

I have checked my outlets with a receptacle tester and it showed as normal.

I have run memtest multiple times.

Windows repair has been attempted multiple times.

I ran a gpu stress test for 2 hours with no crash and temps inside safe limits.

I had HWMonitor on my 2nd monitor while playing and temperatures never got close to dangerous levels.

Virus's have been scanned every couple of months.

I went in to BIOS since getting win10 and changing my fan speeds, temperature safety shut offs(can't remember exact name but it was like at this temp we will stop stuff and try to lower temps.) and some other things but reset it to default after nothing changed.

My friend who worked in tech support irl has teamviewed my computer multiple times and never found anything.


Things I will be trying soon

[strike]Currently reformatting old hard drive and will trying gaming without downloading any programs/transferring some of my old files.[/strike]
Did this, only programs installed were chrome, steam, and teamspeak. Logged in to chrome as well to get my tabs/bookmarks. 99% sure none of this stuff could have caused crashes.

I plan to get a new graphics card, however it was replaced so not too much hope there.

New ram, again though I've shuffled two different sets of 4gb so I don't see that being the cause.

New case, not sure how this could cause crashes in the way it is but it's old and still there from the start so why not.

Out of money though so I won't be able to replace anything for awhile.


Closing thoughts

I've pretty much done everything I can think to do in what could reasonably have caused this, have posted about this in multiple places online, and have given up hope.

As far as "Should have done the whole computer all at once," yeah probably should have but didn't have money full new parts.

TLDR:

Computer started crashing while playing games in 2014, replaced graphics card fan and added ram. Since then I have replaced cpu, cpu fan, psu, motherboard, hdd, and upgraded from win 7 to 10. Extensive testing has done nothing to help.
 
Your first mistake: using two different memory kits in the same machine. No mixing memory, it's known to cause system instabilities.

Try running it with only one of the brands in there, then with only the other brand in there, seeing if this yields any positive results in terms of stability (yes I know gaming on 4GB is going to be painfully slow)

I have tried every combination of my ram possible. I tried one stick at a time, all 4 sticks attempted solo. Tried just one pair in. Nothing changed.

I'm having a similar problem and tried many of the same solutions. What peripherals are you using? Have you tried swapping them? I've got an old Razer mouse, Apex M800 Steelseries keyboard, and X34 monitor plugged in.

One thing that seemed to make the issue stop for me is taking out the GPU and running with the built in graphics on the CPU. There are a ton of reasons this could have fixed it though, and the GPU doesn't seem unstable in most games / stress tests. Also underclocking and increasing voltage on the GPU doesn't help.

Thanks.
