After about 90 minutes of use, my ACER laptop goes crazy - menus start popping up, keyboard won't work - I have to shut it down and let it rest!

Try contacting you computer store or the computer manafacsuer they might be able to help you.

Can you reformat the hard drive or re install windows? you may have to do one or the other but if it were me i would re install windows vista

I there, i have read the comments what others have wrote.

and i must come to the conclusion that it must be a hardware error because when it is a virus than it schould work instantly and not after 90 minutes, no virus does that,

what u can do is this:

1) make back-ups from your important files,photos, and so on

2)when u have done that than put in your recovery dvd or cd

3)now boot your system with the recovery that wil clean your notebook to fabrics instalation

4)when done than u have a clean xp or vista on it, than u can install your software new on it

5)now comes the part to test, when after 90 in start again than we now its hardware and not a very ugly virus

6) if it starts than contact acer for a rma to repair your notebook

It sounds some type of hardware problem.most probably a faulty keypad.after disabling ur laptop keyboard.attach the external keyboardand try.it should work.

It sounds to me like your windows is corrupt and you need to remove it and reinstall from your disk.
Also, try running it without the battery in.(just plugged in to socket)

Hi
here the solution its an hardware problem.using your windows or vistas cd...change it to factory settings..first backup your files in another cd..

"menus start popping up, keyboard won't work "

possible reason for the fault

1 System fault/viruses

This fault is common, the only way to exclude this possibility is by doing a complete file backup, formatting the hard disk and reinstalling the system. Thes is the first step done on repair.

2 Faulty Touchpad /Faulty keyboard/ Faulty Ribbon cable.

This is a common fault that can cause menu popping up as if you click the mouse buttons, you fix this replacing the mousepad, or the keyboard and cables.

3 Bios fault

This is very rare, and is associated to extra functions on button, in this case the laptop performs actions associated with special keys while you type, I don't think this is your case, as it would do it all the time.

Do back up and reinstall the system, if you still get the problem, have the mousepad assembly replaced.

Then this is a problem with the Operating system (OS) you are using.Try to format the OS drive alone and the see if it makes any change.It wont take much time.Software backup nowadays is not a big problem as you get almost every software downloadable.Hope it works,will await your comments.

Hi and welcome to FixYa,

Of course an alternate possibility is a hardware fault. Could you try physically disabling the keyboard of the Acer and use an external keyboard?

Good luck and Thank you for using FixYa. Happy New Year.

It sounds like a trojen or a worm, that has a delayed trigger, or a certain program or key combo is triggering.
Go here http://www.avg.com/ , pickup a trial of the home version, go into safe mode and run it from there, that should do it. They also offer a great "free" home user, version, but get the pro version so we can get rid of that infection first

Have you ran an anti-virus program to scan your computer?

Its a virus problem, first scan your computer with a good antivirus.
