Process will reach full usage every fixed time period?
In the evening I decided to repair my Lenovo Ideapad 5 14ARE05 with a Ryzen 7 4700U that had a broken keyboard. I purchased a new key and spent two hours working on it—tightening screws, soldering, and dealing with some mishaps. Once fixed, the laptop ran smoothly but felt a bit sluggish. Checking Task Manager revealed unusual CPU usage, peaking at 100% regularly. While fixing the keyboard, I had to take everything apart. I loosened the heatsink screws but stopped short when I realized I was out of thermal paste and chose to leave the heatsink on the motherboard. I plan to reapply paste soon; my last attempt was a bit too little. It might not be the cooling issue since the machine isn’t overheating, though I’m not sure. Thanks for your help!
Congratulations on getting your laptop fixed! In the Processes or Details section of Task Manager (depending on your Windows version), right-click the column headers and choose "Select columns." Add "Command line." This helps identify the script running and its actions. Download and execute Autoruns to see what launched it. Look for any mention of PowerShell or a specific script name. Review the Scheduled Tasks tab first. Source: PowerShell launches automatically, uses most memory and prevents game play. - Microsoft Q&A
I'm not sure at all. I couldn't locate any information on PowerShell in Autorun either.
Not necessary to worry, but have you completed a full malware scan? I suggest trying Malware Bytes to check for anything suspicious. It’s unlikely a genuine program would intentionally use PowerShell with those settings unless someone was configuring it. From what I see, it seems like a malicious PowerShell script, possibly a crypto miner.
