Other than leaving it running on the carpet so it "eats" lint, never running Windows Update, or updating & running the anti-virus or anti-malware software.
So a three year old laptop dies completely and it's $$$ for a new one a month before Christmas.
At least the new one is a Dell - and he's using a lap cooler to keep it off the carpet enough to keep it from eating lint & dust.
I have no idea if he's running update & the anti-virus - but *I* am!
I cannot believe this, but the other day I installed some software for a friend in a DVD drive. Day later I was informed that: "The drive has been installed backwards and the DVD fell down".
The computer itself was upside down!
