Dear friend.. the same happened to a customer's laptop.
I suggest you do the following:
First, try to scan your harddrive for viruses in another computer (you can buy a cheap 2.5" USB enclosure for your drive and use it as an USB drive). Once you do that, clean from viruses.
Next step is reinstall the disk and boot the machie again.
If it's a virus problem -as it happened to me- the BIOS block itself and nothing responds, so, you'll have to cheat BIOS.
Plug a flashdrive (any kind) and wait to windows recognizes and installs it. Once it's done unplug it and plug a USB keyboard and/or mouse and wait. Once you have control power off the system normally (THIS IS VERY IMPORTANT TO UNBLOCK THE BIOS).
Next time you power on your computer, keyboard and mouse should work great.
Hope it helps.
PD: One advice... you will probably have to reinstall windows. And finally try linux... this won't happen with it.

One thing you can try (for the touchpad)
Acer have got a function key to turn it on and iff (i thought mine was broken for a year). Hold the function key, which is located bottom left of keyboard, and then press F7. It should be F7 anyway.
Hope that helps for your touchpad

I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

O.K If you follow these instructions to the letter ,I can help you get your system up and running again.Acer motherboards have the CMOS battery hardwired in its frame work and cant be changed This is where your problem is.Unlike most other computer brands you can change out the CMOS battery like a watch battery.
First Dont panic.
Now go to a computer supply store and get a de-magnatised computer screw driver set and cpu thermal paste ( artic silver).
Remove all srews from the back of the laptop
open and remove back cover.
Remove the Hard drive,and ram stick
Flip laptap bak upright and remove title bar strip or power bar strip (its the plastic strip above the keyboard) its only snapped in so be gentle .Remove the screws that are visible here.
Remover keyboard and unplug the circuit stip to both the keyboard and touchpad mouse.
Remove the power plug leading to your screen.
Remove the entire keyboard face plate with a few more screws.
Flip laptop back over and remove the fan the cpu heat sink and cpu.
Follow the wires leading from your screen to the clipset.unplug the black and white wires then remove the chipset.Pull the LCD creen wire through the board and remove the screen from you laptop.
Now all that should be left is your motherboard and dvd rom drive.
At this point your going to empty the information being held by your corrupted CMOS battery by FREEZIN IT!!! YES FREEZIN IT. Put mother board in your freezer for no shorter then 10 hours ,taken it out once ever 2 hour for 10 mins to warm then back to the freezer again. This process will clear the CMOS battery.
Now its time to put all back together.
Follow your step backwards until you reach the point of installing your CPU.
Take a cue tip with some rubbing alcohol and remove the old thermal paste from the cpu and heat sink. Now add a tick tak size amount to you CPU and reseat it in its housing (notice the small arrow on the cpu and housing indicting the direction for the cpu to set.) tighten down retainting screws. and install the heat sink.
Finish the process backwards until your laptop is back together.
Turn your pc on and you should be good to go.
I further recommend backing up all data and reformating your drive.Also change any settings in you BIOS to its default levels.
I rate this process a difficulty of 5 out of 10

hello, this has been one of the most reported problem with the 5100 model. i have 2 of them, and they have done the same thing! one i had 2 find and install a new mainboard-400 bucks! not very cost friendly. i did post a solution more than a year ago, but it is a work around that let me use the acer with the dead keyboard,touchpad,usb- you must buy a pcmcia usb card, it goes in the slot on the left side of the acer 5100. then a usb mouse and keyboard will work. (you can get this cardbus adapter cheap, as 400 bucks is 2 much. these pcmcia cardbus card come with 2 or 4 ports. this will let you use the pc, it has been a great solution for me and a lot of others, been in use over a year like this. acer is no help, unless you wish 2 spend a large amount of $. the one with the new board lasted about 8 months before the usb port stopped working for the second time, i then got a second cardbus usb card and have usb again. sorry for your problem.. good luck! do as i say and the acer will work again.( a problem model) just search for pcmcia usb cardbus you will find many 2 choose from- i picked the ones with the NEC chipset, as these are reliable! be well!
