I have a fairly old dell model desktop computer. Usually I can fix any problems that come up but I need some help with this one. Couldn't say what specs I have b/c I can't remember. The load screen says "dell dxp061 series. Bios revision 2.4.2". The normal OS is XP but I have vista instead. I've been using it this way for 5 years at least. It does not have the old style keyboard/mouse ports, instead it has quite a few usb ports and you have to have a usb keyboard and mouse. I also have a webcam and phone charger plugged into the usb slots. Today.. it started making the sound that it discovered a device and then the device was unplugged over and over. I couldn't do anything with it. I had to forcibly shut down the computer and now it does't recognize the keyboard at all. Windows can't just start up because some time ago the air temperature sensor has stopped working so I have to push F1 to go on. (It's pretty cool where I live and I don't fear overheating.) Anyway, the light on the mouse comes on. The phone will still charge... so.. I am scratching my head a bit on this one. With no keyboard I can't even start the computer up fully to try and diagnose the problem.
