Dahoe Posted February 14, 2008 Share Posted February 14, 2008 Hi there, i recently turned on my PC to find that my mouse wasn?t working. After a bit of playing around i realised that i could only use either my mouse or my keyboard at the one time but never the two at once. I?ve tried various combinations of PS2 and USB mice/keyboards but with the same result. Has anyone any ideas how to sort this or why it happened in the first place? Any help is much appreciated. Cheers, Steve. Link to comment Share on other sites More sharing options...
RobC Posted February 15, 2008 Share Posted February 15, 2008 I guess you are not using a KVM switch, as you would have mentioned it. I am using one, and on one of the two ports, the mouse won't work, and the keyboard lights don't work. Have you tried swapping their PS2 plugs in case they are in wrong slots, or the color codes are incorrect ? Link to comment Share on other sites More sharing options...
Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 No not using a KVM switch and have PS2 connectors in the right sockets have also tried USB keyboard and mouse and combinations of PS2 and USB but still get the same result. Only keyboard or mouse will work. Link to comment Share on other sites More sharing options...
RobC Posted February 15, 2008 Share Posted February 15, 2008 Have you tried uninstalling(drivers) for them both. Then re-installing the drivers Link to comment Share on other sites More sharing options...
Barry Gurung Posted February 15, 2008 Share Posted February 15, 2008 Well when i used Windows XP Media Edition. I did had a problem on gaming while i was playing it. Well you might new to re-install your mouse and keyboard. Try changing the keyboard with new one if you have new one. Or may be if you re-installing doesn't work and try re-installing the windows xp. So it back to normal and new. Link to comment Share on other sites More sharing options...
Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 New development is that now only the keyboard works, PS2 or USB, and if i plug in the mouse, also PS2 or USb, the keyboard won't work either. On top of this the mouse pointer remains on the screen constantly even though it's not plugged in. And it's not in device manager to uninstall.

-Vivicidal- Posted February 15, 2008 Share Posted February 15, 2008 This usually happens when low bandwidth splitters/extensions etc are used. Make sure they aren't going via a hub or anything, that solved the problem for me. Link to comment Share on other sites More sharing options...
Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 PC is on it's own with only power, keyboard and VGA lead connected. Link to comment Share on other sites More sharing options...
Volatile Posted February 15, 2008 Share Posted February 15, 2008 What was the last thing you did, installed, changed before you shutdown your computer prior to this issue? Link to comment Share on other sites More sharing options...
Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 Nothing of note, checked email and a few websites. No new hardware, software, downloads etc. I ran an AVG scan just in case but that's clean. Tryed to run AVG Antispyware & AdAware but couldn't access it with the keyboard (any ideas how?) so ran a spybot scan, also clean. Beginning to think i'm gonna have to reinstall but have 5 users on this PC with their own settings & programs and am afraid they'll be affected by a reinstall, would i be right in thinking that?

Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 Worked out how to run scans by using Mouse Keys in Control Panel\Accessability Options so running more scans now in case it's some sort of Spyware. Link to comment Share on other sites More sharing options...
Thrawn Posted February 15, 2008 Share Posted February 15, 2008 Try a Linux live CD. That will tell you if the problem is software or hardware/BIOS. You can also try resetting the BIOS. You might just have an electronic fault in your keyboard. Link to comment Share on other sites More sharing options...
Dahoe Posted February 15, 2008 Author Share Posted February 15, 2008 Have tryed multiple Keyboards both PS2 and USB and also tryed resetting to Basic and Ultimate Settings in BIOS. Link to comment Share on other sites More sharing options...
google123 Posted February 16, 2008 Share Posted February 16, 2008 maybe its time for a new motherboard. :D Link to comment Share on other sites More sharing options...
Dahoe Posted February 16, 2008 Author Share Posted February 16, 2008 I'm assuming it's not the motherboard as USB keyboard works so why not USB mouse? Link to comment Share on other sites More sharing options...
Dahoe Posted February 16, 2008 Author Share Posted February 16, 2008 Ok, a bit more info, i now have the mouse working but now the keyboard won't work again. When i plug in a PS2 keyboard it just freezes but has no error in device manager howerver when i plug in a USB keyboard i get "This device cannot start. (Code 10)" in device manager. Also i've noticed that the keyboard doesn't even work to get me into the BIOS at startup if the mouse is plugged in. Anyone any ideas?? Link to comment Share on other sites More sharing options...
KiHu Posted February 16, 2008 Share Posted February 16, 2008 PS/2 does not support Hot Swap. If you are unlucky you might destroy something plugging it into PS/2 whilst computer is on. (ive destroyed 2 Keyboard doing that..) or well. PS/2 is not MADE for hotswap, but it can cause trouble. Link to comment Share on other sites More sharing options...
Dahoe Posted February 16, 2008 Author Share Posted February 16, 2008 No i'm always sure to power down and unplug before plugging in/out PS2, so nowt to do with that. Link to comment Share on other sites More sharing options...
RobC Posted February 17, 2008 Share Posted February 17, 2008 When ever you can see one of them in Device manager, have you uninstalled/reinstalled the drivers ? Link to comment Share on other sites More sharing options...
Dahoe Posted February 18, 2008 Author Share Posted February 18, 2008 Yes but same result. Link to comment Share on other sites More sharing options...
RobC Posted February 19, 2008 Share Posted February 19, 2008 Could be a good time to have a 2nd drive. Add a 2nd drive and install xp on it. It is possible to have two drives, each with XP on them. You have to take precautions to avoid 'cross talking'. (Tell system restore not to monitor the other drive) I have a pc set up like that and I can tell the bios/cmos menu which one to boot into. When installing XP on the 2nd drive, I had the first drive disconnected. I don't use system restore on that pc as I use snapshots of each drive (taken while booted into the opposite drive). If you are using it, then you have to get in quick and tell them not to monitor the other drive. I don't use any special software (No Partioning software, no Imaging software) To replace the other drive, I boot into the opposite one, and peep across to delete all the files. I then copy a snapshot (EG from a DVD or two), to replace all the files/folders. The trick is to not reformat, to avoid XP getting huffy. Once you have the new drive, you can see if it has the same problem. Seems like a lot of effort to see if it has the same problem, but you have a 2nd XP which can be very handy. Got to rush out, but can elaborate more later. Rob Link to comment Share on other sites More sharing options...
+allan MVC Posted February 19, 2008 MVC Share Posted February 19, 2008 I'm sorry - he's having a mouse/keyboard problem and suggesting he adds a second hard drive? Link to comment Share on other sites More sharing options...
RobC Posted February 19, 2008 Share Posted February 19, 2008 I suggest everyone have a second hard drive. It comes in handy for all sorts of things. One of which could be determining whether you have a hardware or software problem. Link to comment Share on other sites More sharing options...
+allan MVC Posted February 19, 2008 MVC Share Posted February 19, 2008 Please. I'm not looking to start an argument here, and I certainly feel a second HD is useful for most of us, but it has absolutely nothing to do with troubleshooting (except perhaps to troubleshoot a bad HD).

|Rapture| Posted February 19, 2008 Share Posted February 19, 2008 Poor allan, this is the second thread I've seen today where he offers advice then someone jumps down his throat :p If you're having problems in the BIOS too then check IRQ settings maybe. If they're ok it could be a motherboard issue. Could try a BIOS update if you're feeling adventurous. Link to comment Share on other sites More sharing options...
