In the past couple of weeks my computer shows more and more problems. I think it might be a hardware problem, since most of my setup is 13 years old and it worked before with the same OS. However, I don't know where to start to find out which component causes the problem.
SETUP
OS: ElementaryOS 7.1 Horus (based on Ubuntu LTS 22.04.3
Hardware: Intel CPU i5-2400 (no additional graphics card), 8GB DDR3 RAM, 2 HDDs + 1 SSD, mainboard (in dmesg it says this "Hardware name: System manufacturer System Product Name/P8H67-M PRO, BIOS 1003 05/10/2011")
The hardware I$described above are my suspects. However, the SSD is new and I recently installed the OS freshly onto it (before that I only had the HDDs). The system is now faster, but the problems are the same. So I think it's not a problem related to the drives.
PROBLEMS
Most frequent problem is browser (or browser tab) crashes (both Firefox and Epiphany). Most frequent == multiple times a day. I re-installed Firefox and also tried with Troubleshooting Mode and new profile. Result is the same. I had the impression that it happens more on rich websites (like Youtube) and less when I only read a blog - but sometimes it immediately crashes on startup as well.
Other problem is that sometimes the system completely freezes. Happens from time to time.
Also, I have a problem that my WLAN connection keeps disconnecting and forgetting the password (but I am not sure if that is related).
LOGS
I looked into dmesg and opened firefox via terminal to see error logs.
dmesg:
[ 2868.450095] BUG: Bad rss-counter state mm:00000000bb41f266 type:MM_FILEPAGES val:-1

firefox terminal:
ExceptionHandler::GenerateDump cloned child 8759
ExceptionHandler::SendContinueSignalToChild sent continue signal to child
ExceptionHandler::WaitForContinueSignal waiting for continue signal...
After this the CrashReporter crashed (???).
Please guide me towards how to find out which hardware component (or what else?) might be causing these issues.
