hi ,
i installed windows xp(120 days evaluation version) on my compaq armada m700 laptop.
when i connected to internet spam attacked my laptop.then i formatted and reinstalled xp.
now it works ok but when i connects it to internet or when i use it normally, it says my windows registry is curropted.
now i can't hold my mouse.it goes up or down of my screen and stays there.i can't hold it to click anything.

how can i fix this.

any help in this regard is very much appreciated.

regards and many thanks in advance.

What version of XP is it? SP1? SP2?

You should not go on-line without at least SP1.

I would recommend reinstalling XP & then installing SP2 before you go on-line.

To do this download SP2 beforehand & burn it to a CD. Then after you install XP install SP2 off the disk immediately.

Here is the download site:

I do not know how you can troubleshoot your current install if you can't use your mouse.

You could try Safe Mode.

hi mate,
can i download SP2 from the internet and install it on my machine ratherthan burning it to a CD?

many thanks

(What about your mouse problem?)

If you can download it to your machine you could then run a Repair Install which will leave your data intact. Then install it from your hard drive first thing. A good guide here:

Or else install it first thing from Windows Update. Any time you spend on line without its' protection makes you very vulnerable.
