Hello people ! my PC is getting very slooow. I brought my pc 3 years ago... at that time i loved using it and it never lagged when i played games and other stuff. but few months ago all my hard drives were full so i thought that becoz of it my pc is getting slow. Then i brought a external HDD and cleared my computer. but nothing happened to the performance. Now whenever i watch 2-3 videos continuously on youtube my pc starts getting slow and if i don't to anything my pc shuts down. 2-3 years ago i used to play gta san andreas and bully and counter strike my pc used to let me play games without lags but now if i even play games on internet my pc suddenly shuts down. please help me ! i would be very thankful !

I'm guessing that you haven't cleaned out your CPU heatsink in 3 years or inspected the thermal interface material.

Hello... 1) a fast way would be a clean install of your OS and Programs... that fresh clean feeling... will speed things up.

2) Do you know how to Display hidden files/folders? because I can show you where to find all that 3 year internet/temp/ files are hidding on your hardrive. B )

3) Go to folder Windows/temp delete all files here.
4) Right click C: Drive-Properties-Disk Cleanup- (check mark all boxes) Clean up system files- (check mark all boxes) OK

haha I was about to write the 2 above posts! Put all your files on your external drive, format your hard drive and clean reinstall windows. Open up your PC and clean all the dust out of it, take out the ram sticks and blow on em and put them back in, take off the CPU heatsink and clean it, unscrew the fan and clean, then clean off the thermal paste from the CPU and heatsink with rubbing alcohol, then reapply thermal paste and put it back together, you will notice the difference!
