i found a version of windows and am now re formatting the laptop…
On this Acer Travelmate 2310 and many other Acers, there is a recovery partition on the hard drive that will restore the machine to its exact factory condition, so it's just as if it came out of the original box….. it will have a fully functioning and activated copy of windows on it together with the Acer applications that shipped with it…
Let's hope that you haven't formatted this partition by mistake….. if you have then, then you will have destroyed the recovery parttition making it impossible to recover by this method…..

.
If you have left the Recovery partition intact then this will have you up and running with a fully restored machine in less than 15 minutes. This is how to do it:
Restart the machine and immediately after pressing the power on button hold down the ALT key and press F10 key
If the recovery partition is undamaged then this will take you directly to Acer Recovery Management…..just follow the onscreen instructions.
If this does not work it indicates that you have lost the recovery partition so will need to use the Microsoft Windows installation disc, with the product key that is written on the COA found on the bottom of the computer……..
This latter procedure will be required if you found that your hard drive was unservicable and have replaced it with a new one. However if you buy the hard drive direct from Acer or one of their approved service centres, you can ask them to have the recovery partition included and this is usually done at no extra cost (over and above the cost of the hard drive.)
If you have used the latter method (fresh install using a Microsoft windows installation disc, then its strongly recommended that once your machine is running fast and sweet and configured just as you like it ( that is to an "ideal state") then take a disc image, keep it safe on removable media, verify it for accuracy and reproducibility and make a bootable CD (with a disc imaging application) then in the event that you ever hit trouble in the future that cannot be rectified in a timely or cost effective way by the normal means, you will be able to reimage your machine back to your "ideal state" in less time than it takes to walk the dog!
Post back if you need details of disc imaging software, there are commercial (paid for) applications, but also lots of free ones that are perfectly satisfactory.
