I have a Toshiba netbook NB100 which is very slow when I am checking my emails. Every now and then a box appears warning me about unresponsive script with a large paragraph of meaningless (to me) code. Does anyone know how to fix it? I'm out of work at the moment so will need a cheap, preferably free solution.

when it happens again, can you print screen it and post it here, will be able to help more if i know what it looks like, alternatively get in touch with TheDr

he'll probably know exactly what your problem is and how to fix it.

Because your netbook is running so slow its possibly over loading the processor and causing scripts to fail. This is why its happening now and then.

Or

You have a corrupt file and need to run a disk check.

Try the disk check and take it from there.

Try using a different browser (If you are using webmail)

Thanks for the advice, I'll try a disk clean up.
I'm not sure how to paste the image on here. I can print screen but can't paste it.
Hopefully the disk clean up will work.
