Phantom: All replies above are good advice. My son actually has a 4 yr. old version of that sidewinder gaming mouse on his $1,300 Qosmio gaming laptop and he has no problems.
One thing that you can try also that wasn't mentioned, is to get a "Vanilla" corded Microsoft Mouse from a friend or you can still buy them for $10 or so on eBay or Amazon and plug that into your Acer laptop.
All versions of windows are hardcoded in the kernel to use built-in Windows drivers by Microsoft! Therefore, when you have a problem with a internal Mouse or trackpad device or a Mouse/External Mouse combination (either external PS/2 or USB); I found out years ago that when you hook up a Standard $10 wired Microsoft Mouse (and I don't mean a knockoff here, it has to say MICROSOFT somewhere on the top or the bottom label) to a computer having device driver problems on the mouse, internal or external, the best way to troubleshoot this is to disable any/all internal TrackPads, pointing-stick devices (usually only on ThinkPads and Lenovos), and plug in your $10 Real-Deal Microsoft mouse. It shoud work, as their is no external driver to load; the MS Mouse either works or it doesn't. If it works, then you know that the USB or PS/2 port on your laptop is good, and your Mouse (sidewinder in this case) crapped out!
Not to surprising since you say you dropped it and heard it crack?
Further troubleshooting advice: When your wireless external mouse fails, plug in your $10 Real-Deal MS Mouse. If that works, your USB or PS/2 port is good. If the $10 Real-Deal MS Mouse works, chances are your wireless external mouse is gone or the batteries need to be changed. If you have an external Mouse (USB or PS/2) that uses a 3rd party driver such as Logitech or Kensington and that will not work, and neither will your $10 MS Mouse, it usually indicates you have a bad port on your laptop Motherboard. Remember, while testing external Mice, you must disable any and all embedded mouse or trackpad devices in your laptop BIOS.
Occasionally, when troubleshooting this type of problem, a Windows reinstall will resolve this problem. That is if the problem mimics a faulty USB or PS/2 port on the Motherboard. Running full hardware diagnotics on your Motherboard, RAM memroy, and Hard Drive will help you narrow this problem down. If all your hardware diagnostics pass, it's most likely a corrupted Windows install, and that has to be repaired. This problem occurs maybe only 30% of the time. Usually when I use the $10 MS Mouse method, it points to a defective external Mouse that has broken, and driver replacement update cannot fix broken hardware! And I always keep a few of those $10 MS Mice on hand--in fact I collect them just for this sort of thing.
Methodology here then is to disable internal TouchPad device-->Plug in $10 MS Mouse to Test. If $10 MS Mouse works, port you are testing on laptop is Good-->Replace faulty external Mouse. Pretty Simple!
If $10 MS Mouse fails in above test, port is bad. If it's a PS/2 mouse port, you're Motherboard is done, and it cannot take another cause most modern laptops only have 1 PS/2 mouse port if they have one at all. If it's a USB port you probably have 1-3 more you can repeat this same test on. Sometimes, only 1 or 2 USB ports will fail on the Motherboard not all at once, and you may just have to switch your sidewinder mouse to a different USB port. Of course if the $10 MS Mouse test fails on
ALL of your USB ports, then the USB controller chip on your laptop Motherboard is toast. At that point, you either suffer along with re-enabling your TouchPad device, but I suspect you can't really use that on your Gaming. You either replace the laptop Motherboard $85-$175 plus labor unless you do yourself; or replace the laptop!
Good luck!
