Apologies for a potential wall of text, but I want to describe my problem thoroughly. It started about 6 months ago, however it was a very occasional issue back then. It continued to occur more and more often, then randomly stopped happening altogether for almost a month around September and now occurs almost every day. Basically:
- the problem doesn't occur every time - it's very random
- it occurs most heavily while playing games (mainly playing Dota 2, but affects other games too)
- the screen starts lagging, looking literally like a slideshow, making the game unplayable, the PC as a whole works a bit more slowly as well, e.g. slower switching tabs in Chrome etc.
- the sound starts to stutter as well, also sometimes disrupts into a robot-like sound, making it completely inaudible and delayed - not only affecting my headphones, but sometimes also my microphone as well, which according to my friends sometimes makes me sound like a robot on Teamspeak (hasn't occured recently though)
- most of the time these days I don't really play any games, which makes only the sound issues to occur
- the longer the PC is on, the higher chance for it to start
- after it affects the game, after shutting it down, the sound issues also remain when I play videos in Chrome or music from my PC.
- if I remember correctly, back when it happened for the first time, I restarted the PC. During the boot, there was a beep-sound and a warning message (BIOS?) displayed about a high CPU temperature.
There are several other issues I've noticed in the past year, perhaps somehow affecting it(?), but are either not as frustrating or happened only once:
- connected to the previous point: the CPU temperatures. This used to be a worrying issue with 60-65 degrees Celcius while only doing some browsing on Chrome and with 73-86 degrees while playing Dota 2. I will attach several screencaps from HWMonitor along with the BSOD analysis.
- HOWEVER, after running the Tron script from Reddit, it seems the temperatures have improved greatly - now are around 40-45 degrees while browsing and 60-75 during gameplay.
- One GPU fan seems to not be as smooth as the other - while one is easily whirled with a finger, the other stops right away. When the PC is running, the faulty fan does whirl, but ocasionally (~once a minute) stops for a very brief moment. I'm not sure how important it is, because my GPU temps seem to be fine, as you can see on the attached screencaps. Not sure if it still stops after cleaning it today with compressed air.
In order to diagnose the problem myself, I've tried to do everything to check if it could be a software issue. What I've already tried:
- Thoroughly cleaning the PC both physically with compressed air
- Cleaning virtually by running numerous anti-malware and other programs, the Tron script as well, all of which I have found from some cleanup guides on Reddit.
- Freeing lots of space on all partitions
Even though this thorough cleanup did help to some extent (the temps are lower), the problem with heavy stuttering and disrupted sound still remains. I have also purchased a CPU cooler with thermal paste in a heat of the moment, but due to the above facts I have a reason to believe it will not fix the issue either as the problem lies elsewhere. Because of all that, I have a feeling it's more likely a hardware problem, unfortunately one that I can not diagnose easily because I have no spare CPU or motherboard to temporarily swap. What I can add is that my RAM sticks and drive are relatively new, so they are most likely not the problem. No drive or memory errors from the test programs I've run either.
The Speccy and BSODInspector scans (for some reason couldn't run Sysnative) were both run while the PC was experiencing the problem with Chrome, TeamSpeak, Steam and Dota 2 on. If there is a need to do it while idle and when it is not currently happening, please let me know. Apologies for the Polish system language, but from what I've found on Google, it is impossible to change it on Windows 7 Home.
I would greatly appreciate it if you folks could give me your thoughts and ideas on the matter, as I am currently in a tight spot financially, simply buying a new PC is not an option.
