My laptop Asus f3t series
will not show any thing when started up the on light goes on but nothing else happens
It was working fine last night and really have never had any problems before
any ideas how to fix this or why it may have happened?

Have a look here: Tutorial: No POST (Power On Self Test)

My laptop still didn't respond
it did exacly the same made all the right noises the light came on but the screen stayed blank

Please plug an external (PC) monitor, securely into the back of it
And try turning it on again

Tried this and nothing appeared

You will need to follow the above guide in more detail
Remove battery\HardDrive\all externals
Reseat Ram (try one card only)
Possibly, open it up! (ie dimantle)

To be honest im really a computer novice i have no idea hoe to reseat the ram nor dismantle it

Many manufacturers provide guides (including pictures) that you can download (by the way, I'm repeating on every post here, what's already written in the guide)

But with all power out
Turn the laptop over
You should see a couple of covers (usually with one screw, holding in the cover it self)
Remove the covers
Reseat the Ram (they click in and out)
Reseat the harddrive

Did you at least manage to remove the battery?

If you can post a picture try to, that will help people point you to what you should open.
