Hey everyone! I just fixed some old PC problems because of bad RAM, but now it feels slower than before even though I spent so much money on it. It struggles with doing multiple things at once, and sometimes it has to close my browser while playing games because the game gets lagging. (No internet connection problem) Even opening simple apps like Windows Explorer or Task Manager is hard, and moving windows around takes a minimum of 5 seconds for the computer to react. Here are my specs: Intel i7-10700K processor, 64GB RAM, TUF B560M Plus motherboard with Wi-Fi, Kingston SNVS1000G SSD, Nvidia GeForce RTX 3070 card, and three Predator XN3 GPUs connected to monitors. According to Task Manager, the CPU is sitting idle at around 30% but jumps up to a minimum of 80% when I try things like opening new tabs in Chrome or Firefox. I have checked overheating and bad hardware by swapping parts one by one without any problem changing, so I think it might be software related. I talked with tech friends for ages and searched the internet but haven't found other solutions that aren't just generic "computer is slow" issues. Anyone can help me? Thanks! Also, as a side note, why does my computer lag or freeze for a second every time the desktop background changes? What's going on there?
