I'd advise to get Speccy (freeware program) to tell you what you've (now) got click here filehippo.com
Speccy will give you detailed statistics on every piece of hardware in your computer. Including CPU, Motherboard, RAM, Graphics Cards, Hard Disks, Optical Drives, Audio support. Additionally Speccy adds the temperatures of your different components....etc
Burn-it, yes I agree. Just trying to make sure that it was 64 bit on before (certainly seems it would be as got 16GB ram) However I wouldn't post advice to go charging back to shop complaining unless I was really sure of my facts and that includes what's now installed.
Also unknown is whether it's (Big Name) OEM pre-installed OS or if it's Retail.
Fruit Bat /\0/\'s post did ask for details of the pc.
