The patient: Dell G3 3579 - i5-8300H / 8GB ddr4 / intel SSDSCKKF256G8 sata ssd(latest firmware from dell) / latest 1.10.0 bios from dell Running 10 Enterprise LTSC x64 on it - no heavy modifications / chopping done, only has integrated updates from the catalog and disabled defender in gpedit. I've ran LTSC on my previous laptop with no such issue. Now, I get random cpu AND/OR ssd usage spikes and the system freezes for couple seconds(or enough to tick me off quite a bit). Doesn't matter if I play a game(mostly wrath of the lich king and age of mythology) or watch a movie(potplayer) or simply browse the net(firefox). Whenever one of the two(or both simultaneously) spikes occurs, there's a noticeable unresponsiveness in any action I try to perform, even opening task manager. Whenever I open up task manager, I see that it kinda needs to catch up to the situation, because it shows normal usages for a few seconds and then refreshes to reflect what's pegged at 100% usage(either the cpu or ssd). The weird thing is, if I sort the processes by cpu or disk usage beforehand, just before task manager catches up, I can see System Interrupts, Runtime Broker, Windows Shell Experience Host, System and other such processes hogging said resources. I've tried clean install and kaspersky rescue disk on a usb stick - negative - no viruses, other than the Microsoft Toolkit on my 1.5TB hard drive, which I'm obviously not taking seriously. I've read about problematic drivers causing issues but in device manager I have no such drivers. Also, all the drivers I'm integrating/installing are from dell/intel/nvidia directly. I honestly have no idea what the cause can be, as I don't see any dependencies for this issue. The thought of some weird miner had crossed my mind, but then again, I'm really not the person that clicks stuff like "fReEcDkEyS.CoM". Any input would be greatly appreciated.
