My vistro 1510 has started acting up, first the screen started having all kinds of werid displays and would not boot up, I then turned off computer and let reboot up and all was ok, now its doing it every other time or so I try and start computer, when its acting up there is a number 9 in a small box (like a lock) at the top that is flashing......whats up???? Help, who can I take it to to try and fix if necessary.

just push "num lock" button :).  This flashing Lock symbol [9] means "Num Lock" is on - numeric keyboard enabled. If you wish turn it on or off just press the <Num lock> key, sometimes you have to use the <FN>+<Num Lock> keys.

Possible memory issue. Try Reseating your memory card on the system, it would be helpful.

The issue is not clear!! pls be more specific

SOURCE: on boot up a lock symbol with a '9' is lit & nothing else happens

the "9" inside a lock means that your Num Lock button has been pressed. If all you see is the ">" then maybe you are looking at what's called a DOS prompt, and I have no idea why that would display. Try holding the Power Switch for 10 seconds and restart your computer. Hopefully things will be better, and you know where your Num Lock key is.
