Acer eeePC keyboard, usb mouse, trackpad frozen

Hit the windows key on your keyboard and use the Cursor keys (up and down, left and right keys) and the enter key to work as a left click

Are you using the trackpad to manipulate the cursor, or are you using an external mouse?

If you're using the trackpad, it may be as simple as using the Fn keys and the corresponding F keys at the top of the keyboard to enable the trackpad feature again. If that doesn't work, try plugging in an external mouse via USB port to see if that works.
If you're using an external mouse, then try to see if the cursor moves while using the trackpad.

Hopefully one of these options will give you control back over your cursor again.

1) Is there any accidental liquid or water damage on the keyboard, if there is possibly the keyboard and track-pad fails cause it may have affected the circuitry in it.

2) See if you can access the BIOS and try to reset to factory/default settings. Save and exit. May resolve the trackpad and keyboard issue. From the BIOS you can individually disable stuff built into laptops like USB, card reader, etc. At banks and businesses, they usually disable USB controller cause you know work policy.

3) If you want to know if its hardware or software issue. Suggest you try with Linux distro like Ubuntu. Burn to a disc or make a external USB pen drive and boot from that. If the keyboard and mouse work in Ubuntu, then its a software issue. If it still doesn't work, then its hardware issue. You don't need to install Ubuntu, you can run it without installing it. Although you can install Ubuntu alongside Windows if you want to.

4) Sometimes driver issue, use the manufacturer driver, or check windows updates for the drivers. At this point i would suggest getting an external USB mouse and keyboard just to do this.

At boot up, go into bios setup and ensure that the USB Keyboard/Mouse is set to enable

Sound like you might have a virus - try running antivirus program - such as Avast or Antivir - which is free.
If that doesn't work, then try doing a System Restore - if that doesn't work, then do a System Recovery complete re-install - but back up your pictures and documents first as you will lose everything and you'll be starting over again fresh.

Sounds like a hardware problem with your trackpad or your keyboard. I suggest attaching an external mouse and keyboard, then disable the touchpad and keyboard drivers in device manager. Reboot and see if it still happens

You may have a motherboard failure problem. I would ask you to check the drivers and update them but will be hard to do if you can't get past load screen. You best bet may to get a copy of system recovery and boot pc with the disk installed. Wipe computer completely clean and reinstall windows.

Check the processor on the machine first: is it seated properly, is the cooling fan turning on it. Next, reseat all of the memory modules in the case. Finally, test the keyboard and mouse and confirm they work; try a different keyboard and mouse on the machine. Listen for any unusual noises in the case (any noises that sound out of the ordinary), try running the machine with the side panel off if possible.

If your mouse will not move, it is a problem with the computer, Make sure you're plugging it into the correct port. If it's a ps2 mouse don't plug it into the keyboard port by mistake.

Does the keyboard work? If you press the windows key does the start menu come up?

If the keyboard works, try using a USB mouse. If the keyboard does not work, try plugging the keyboard in where the mouse is and the mouse in where the keyboard is.

try plugging in an external keyboard & mouse, hopefully that should work
