I'm suddenly having troubles with my mouse again today. I had some problems\nwith it several days ago after having the computer off for an hour or so to\ninstall a new hard drive and DVD burner - see my Installation Problems\nthread if you want details - but it finally started working again and has\nbeen trouble free for several days. Then, a couple of hours ago, it stopped\nworking again for no obvious reason.\n\nThis is a desktop computer and it really slows me down to have to do all my\nnavigation via the keyboard so any help anyone can render would be\nappreciated.\n\nI'm not a hardware guy and I'm not sure what's relevant so I'm going to\nthrow out all the information I can to help you figure out what's wrong. I'm\nsorry for any red herrings or irrelevancies that I may give you.....\n\nI'm running Windows XP Professional SP3 with the ASUS M3A motherboard and 2\nGB of memory. The mouse and keyboard are both Microsoft wireless models that\nshare the same base station (or whatever you call the thing that is actually\nhardwired to the USB port and transmits mouse and keyboard signals to the\ncomputer). I've checked the mouse and battery is good. The keyboard works\nfine, as you can see by the fact that I'm typing this note ;-)\n\nThe computer started acting a bit squirrelly a few hours ago as I was\ncopying several large folders from one hard drive to another. (They were\neach 5 to 10 GB in size and, as you can imagine, it took a noticeable amount\nof time for each to be copied from one drive to the other.) As I was\nwaiting, I played some solitaire computer games and periodically noticed\nthat a mouse click would lead to a beep. It wasn't the standard Windows beep\nthat you get when you click on something you shouldn't. This was a longer\npurer-toned beep. I've heard those periodically before on this computer and\nthey typically meant the system was about to have a Blue Screen of Death:\njust a single one of those beeps was inevitably followed shortly by the\nBSOD. I haven't had one of those in several months - and they were always\nfew and far between. But today, I heard that beep several times and it was\nNOT followed by a BSOD. I was happy about that but given that the computer\nalways seems to work fine after a BSOD and is definitely not working fine\nnow, I'm thinking that a BSOD might almost be good news now....\n\nI could go through the rigamarole of trying different mice in different USB\nor serial ports like I did last week after installing the drive and burner\nbut that seemed completely ineffective - the original mouse just started\nworking out of the blue that time - so I'm going to hold off until I get\nyour advice.\n\nLast week when I had this problem, someone told me that they often lose\ntheir mouse when the capacitors in the computer discharge but that it comes\nback when they reboot. I've rebooted several times but the mouse still isn't\nback; it's just frozen dead center in the middle of the screen.\n\nWhat can I do to diagnose this? I'm guessing that there is some kind of\nhardware issue causing this but I'm not sure why it would have started now;\nthe mouse worked without difficulty for over 2 years until last Monday, gave\nme trouble for a couple of hours, then started working again for another 10\ndays. Now it's on the fritz again but I haven't done anything in the last\nfew days that would affect the hardware.
