Hi all.
I've been trying to fix this issue for a while.
Random freezing-hard drive light goes out, fans and dvd drive still function,just nothing responds till I hold power down and reboot.
I've tried replacing RAM and got a new internal hard drive. Re-installed Windows, updated my drivers as best I could, and still occurring.
Only constants I've used software wise is Avast AV and Firefox.
Any help would be greatly appreciated, I've tried swearing extensively and threatening to leave it in the rain LOL.
It's a very old laptop-
