Laptop feels like its going in slow mode but can't find anything wrong
Hello people on tenforums, I am losing my mind, and I am deferring to your expertise. About a year and a half ago I got my mother a Dell Inspiron 15 7569 2-in-1. This computer, being a typical Dell, started showing issues as soon as I told the Dell where they can sell their extended warranty. It was subtle at first, a few crackles in the audio, excessive slow down under load, didn't bother my mother. Eventually all sound coming through the internal speakers sounded like it was going at one half speed, and filled with static, the computer was slowing down. The slowing down wasn't bothering her, the audio interfered with her work so she bought an external portable speaker set, and they worked, until the computer reached an even slower stage and the audio started having issues with audio from the 3.5mm port. At this point I reinstalled Windows, I first used the Windows refresh function to keep the data, still having the same issues, so I did a completely clean install. Still the same issue. I decided it's the hardware, the hinges broke anyways so those had to be replaced regardless. Bought a new motherboard because that would get the motherboard, audio card, and CPU all at once (and of course a back cover with hinges and a new antenna). Replaced them all, same issues. Replaced the RAM, same issues. I put her SSD in my laptop (since its an M.2 Sata III SSD) and no issues. I couldn't test another drive in her computer because the only other M.2 Drive I have is NVMe and her laptop didn't see it, since it doesn't support NVMe. But nothing I did changed anything. The sound almost sounds acceptable through the aux port, if the computer is using absolute minimal resources, and playing a file off the SSD. As soon as you do anything else, audio starts screwing up. Apps take forever to open, respond, web pages take 10 times longer to load than on any other device. Just for shits and giggles I booted up into Ubuntu MATE live, no issues. Windows is entirely updated, even not updated, I tried the latest generic audio drivers, I tried going back as far as a year and a half for the drivers. I'm not sure what to do. Installing intel graphic drivers is also nearly impossible, it wont install them over the Dell ones, but every time I uninstall the Dell ones windows installs them right back, even offline or when I kill Windows updates. I'm lost, completely and utterly lost. I have never seen this. It seems like it might be the CPU not being able to function under load in Windows, but that would mean thats the case on this new motherboard I bought too. Oh and the battery is 100% dead after a year. Wont hold a charge enough to even start up the computer.
