what all u have to look into for buying a second hand computer?

Answer 1

The specifications (i.e. CPU, RAM, video, etc.) are really up to you to decide. These depend on what you are planning to do with the computer - if you're a heavy gamer, then you'd need a faster processor and more RAM, but if you're just a casual Internet surfer, then any recent model may do as well.

If you are getting it from another person, make sure you get to see it powered up. Make sure everything works - all the keys, mouse buttons, functions on the monitor, etc. Also look at the case to see if everything looks good - CD/floppy doors working, all ports on the back present and working, etc. Then check out the operating system and any software. You don't have to run everything, but just a cursory look will do in most cases. Definitely insist on all copies of the software, whether it be the system restore disks that came with the computer or all the program disks that the owner may have used in setting up the computer. It will definitely help you in the future in case you have to rebuild your system due to a virus or hardware failure. If they don't have the software, I'd ask for a pretty decent discount to cover costs (a new copy of Windows XP Pro, for example, can be eBay'd for around $150).

Same goes if you are getting it from elsewhere - pawn shop, retailer of used computers, etc., but definitely check out their warranty. If there isn't one, you may want to look elsewhere. A 30-day warranty is usually enough for you to find anything that may be wrong with it.
