Hi. Registered, because this problem has just recurred after a month. This first started happening on 2nd January. View: https://imgur.com/nMZxCGG


It was then happening for days, as I was trying to find a solution. As this was happening my old GPU died, burnt? I have no idea, but it couldn't run as it used to anymore. GPU was not very old. I then found a temporary GPU for the time my PC was at some service centre, where the guy said he "ran some diagnostic through" and it was supposed to be solved from there. Then I bought a real GPU, which I am currently using - AMD Radeon RX 570. Everything was working fine for more than a month now, but today it has happened again. The monitor loses (lost) its signal and I have no other choice but to restart it. The sound stays on, everything is continuing and still happening in the background. But I cannot see anything. Tried control+alt+delete, nothing happens. As I restarted today, my startup loading screens that show were different colours and I thought my new GPU got burnt as well. I do not want that to happen, as it was an expensive purchase.

I have a hunch this happens only when I play "pc-demanding" games, at least for my pc? I was recently playing Resident Evil 2 (just installed it, played for 1-2 hours) and then it crashed. I had fps limited to 50 though, but I think it could be connected to my CPU? Maybe it is one of my cables that got old/bad? I can take pictures. All of my parts in this computer are very old, like HDD, which has over 35k hours spent. The motherboard is old too MS-7522 and does not support DDR3 for SSD, so efficiency would be halved. My CPU is Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz. HDD View: https://imgur.com/Nl7Lh1I


I can specify all of the components in my computer if necessary. I also think it's worth mentioning that every time I ran memtest86 with OLD and TEMPORARY GPU it never finished, lost signal to the monitor and had to restart. Since that and since I got the PC back, I have not tried that yet, as I was afraid to mess with the GPU. I also do not know where the crash logs or logs of MemTest are stored, if they do get saved. Also since today's reset, this is showing but it does not identify which app or software is not working correctly. View: https://imgur.com/aqV1Gep


If I am posting on the wrong website, can you please redirect me to somewhere, where my problem can be identified and hopefully solved?
