Did your old computer have XP when you got it, or did you buy XP as an upgrade? If the former, you're kind of out of luck, friend. If the latter, just do the same as you did to upgrade.
Your computer is either old, needs and upgrade, or has a virus
You can do whatever you want. I have several computers that are more than ten years old that still run fine doing what I need them for. Never buy a computer that does not meet your needs just because it is newer or people tell you that you need to upgrade!
You may not be able to upgrade because certain components in your old computer may not be compatiable to some of the new components in a new computer.I would suggest buying a new computer,basic then upgrade how you like.
You cant unless you upgrade the components of the computer, and maybe even the OS
depends what computer you have or how long you had it. a very old computer can take about 6 hours and a new computer can take about under 10 minutes
specification is how good it is say you have and old 1.3ghz slow computer and a 3.8ght Intel i7 then the speed is an incredible difference and also the better the specification the faster and better a PC can run and to upgrade a PC you replace the lowest graded part
No idea what you mean by 'old fashioned' ...
as in.... good to use? yes they are good to use. it doesnt really matter how old your computer is, as long as it runs alright.
False.
Neither. Get a new computer.
No, it doesn't. Some Anti-Virus programs may detect it as a virus, although this is not true. Still, it's a good idea to not install it if you have an old or full computer, as it could really slow your computer down.
