Why do I lag until I open Task Manager

[l0udXD]

When I open Task Manager I go from 70+% down to like 6%. Sometimes when play games and I really start to lag, but when I just open Task Manger it fixes the issue. Could someone help thank you.

Use HWiNFO (check sensors-only) to monitor your CPU usage and see if everything seems normal there, I'm thinking it's some kind of mining virus that turns itself off once you open Task Manager so it keeps itself hidden?

 

Also just to note, it's pretty normal for the CPU usage to spike when you open Task Manager, on my 8700K it spikes to 60%, but since you mentioned that the performance is different with Task Manager open that's why I suspect it's a mining virus.

It could also be that if you tab out of your game it turns down fps and such some programs run with 10 fps max when minimized.

This sounds like a cryptocurrency miner that terminates itself once it detects a running instance of Task Manager. Run Malwarebytes or a Windows Defender scan.

Fear keeps the programs in line. Fear of Task manager. 

 

Id check task manager and see if you notice high CPU usage and maybe an idcation of what is using all your CPU power. May also be wise to do a virus scan and use MalwareBytes as Ive had great luck with that. Make sure the system is clean.

What should I be looking for in HWiNFO. I have a screenshot of what it looks like
