what age should u be to have children?
To start you should have at least 1 GB (1024MB) of ram to run Vista properly (the 512MB min requirement is rediculous). My friend got a Vista laptop with 512. Out of the box there was like 59 processes running (my xp has 17 running) and it was taking over 448 MB of ram just to run the computer, without any applications open! Buying another 512 Stick was a huge improvement. If you only have 512 MB, you should buy another 512 at the least. For not much of a price difference I'd seriously recommend buying 1 GB stick, if available for your laptop. Even if it ends up being a different problem your computer using experience will be so much better. You said you can't return it like this. I think the like this would be a good reason to return it and maybe get a different one. I am guessing it's just the RAM, so give that a try first.
alarms only panic (when someone breaks in) for a minute then automatically shuts off to save battery. but unless the installer doesn't hide his alarms, they can't just be cut.
