Wont touch Dell as all of their "service" is out sourced to India!!
Ya I know its a world market but nothing pisses me off more than having to speak to some "tech" who can barely speak English.!!
I always buy my computers locally & fortunately, the guy I work with for home PC's & my business laptops is also a good snowmobile buddy of 20 years. Yep, they cost more, but its like sleds & most other things, ya gets what ya pay for!!
So..........if I have a problem, he not only speaks English, I know where the hell he lives & where his sleds are sitting.........LOL!!!
As stated above, no subsitute for good virus software & you need to spend a few $$ to save a few, ie the laptop. Dont screw with it too long if she's slowing way down, that can be getting close to major hard drive crash!
Nieghbor just went through that, lost everything including 5 years of family pics etc. Dumb not backing up at least once per week if you use it a lot
Remote hard drives are so cheap now there is no excuse not to back up weekly!
Good luck
