I noticed that while idle, my laptop fans would start running fast and noisy for about a minute and then return to normal. I checked with MSI Afterburner and found that there are periodic spikes in GPU temperature and usage with corresponding spikes in the core clock, memory clock, and memory usage. This is very weird since my laptop is idle and not running any programs. I checked for any unusual background processes and found nothing.

Consider using app monitoring softwares like Process Hacker to see process that's eating up system resources, debug software and detect malware in the system. This should also show hidden processes that the normal task manager can't show.
