zach   234 #2 Posted November 4, 2020 You say "last few weeks" Was it OK before that or a bit slow back then?  Obviously the first choice would be an SSD, but...  First, try the items below.  Full virus scan Malware scan OS updates Disc clean up  Also, post a bit more info on the system...CPU, RAM and OS/version etc etc.  The extra info will help us to help you 😉 Share this post Link to post Share on other sites Share this content via...
swarfendor437 Â Â 14 #3 Posted November 4, 2020 To check if it is potential mechanical HD failure do a search for .chk files - the more there are the more it is a sign of potential hard drive failure. Share this post Link to post Share on other sites Share this content via...
Ghozer   112 #4 Posted November 5, 2020 If it's "Sys Main" as you described, it's something to do with Superfetch indexing your PC hard drive...

swarfendor437 Â Â 14 #6 Posted November 5, 2020 Searching for *.chk files is just a case of making sure that hidden files are shown (I think) - been such a long time since I used Windows!

I think might be compter's last legs.    If your hardware is okay I'd go for a fresh install of win10, lots of tutorials on YouTube you could follow.  If your wanting to upgrade for better performance adding more RAM and a SSD will definitely make a difference, along with a fresh Windows install. Share this post Link to post Share on other sites Share this content via...
