My computer has recently started to act up. My CPU and my GPU sometimes just sky rocket , my RAM seems to use up a lot more memory than it did before for seemingly no reason as i don't have many background apps running at all. My hard drive, when i check in the performance tab in task manager, sometimes maintains a solid 100% active time with a high response time for a long period then drops to somewhere near 0% active time with a low response time. I tried checking if the temperature was a problem but it seems to maintain a good temperature. I have no clue where to even start to troubleshoot this as it all seems extremely vague. Any help would be greatly appreciated.
