I formatted my computer, and after installing windows 7 again, my physical memory in task manager is very high, and cpu keeps jumping up and down.
I looked at the processes tab, but noticed absolutely nothing taking abnormal memory (private working set.) Then moved on to performance tab> resource monitor, and found svchost (I think it was netsvcs in parenthesis,) hogging all the memory. After ending the process, I still have had high memory usage, and surprisingly, do not see a process anywhere in task manager with high numbers next to it, so I have no idea what's happening.
I have noticed that my windows 7 folder keeps increasing in size, currently about 26 gigs, and a helper told me that it's normal because the updates in windows 7 have a different compression method than windows 8 and after, however when I had previously installed windows 7, fully updated... my folder size was normal, so I assume it can be done?
I originally posted in the Virus, Trojan, Spyware, and Malware Removal Logs section, however I did not find malware on my computer, so unless it's very new malware, I am certain windows 7 is causing this problem.
For antivirus, I am currently using a free trial of Norton.
P.S. This is probably better for the hardware section, but can constant high physical memory, and cpu usage ruin my hardware? I am avoiding using things that take up high cpu and memory right now, and it's currently about 1.2 gigs phy memory, cpu jumping usually 0% - up to 15%
