So awhile back I swapped out my hard drive and ram in my laptop and immediatly after I noticed my pc was running insanely slow after a lot of troubleshooting I found that prochot was throttling my cpu to 400 MHz per second. Disabling it stops the cpu from throttling. I tried putting the original components back which didn't work, reinstalling the windows, trying a different OS. My laptop feels cool to touch even when the fans are loud and I get this weird thing where the fan will be loud for a 10-30 seconds then quiet for 10-30 seconds in an endless loop. It throttles the second I log in too even after being left off all night in a fairly cold room. I Also tried cleaning it multiple times and made sure to clean it while replacing the parts. Do you have any idea whats causing this?

  • You broke, or left off the sensor on the new drive? iMacs were notorious for this, I assume they are not the only machine ever made with a thermal sensor on the HD. – Tetsujin Jul 10 at 17:36
  • "as throttling my cpu to 400 mbs per second. " - CPUs are not measured in megabits/sec. What unit are you attempting to use? – Ramhound Jul 10 at 17:42
  • @Ramhound megahertz sorry I always do that. – Mage in the Barrel Jul 10 at 18:25
  • @Tetsujin as I said returning the original drive did not work also I'm pretty sure it was intended to be replaceable since there was only 1 screw and some pins holding it in it also had the pin layout for other types of drives. I think the original was sata and the replacement was nvme. I just checked the original drive there doesn't seem to be anything damaged either. – Mage in the Barrel Jul 10 at 18:31
