I just recently dusted off an old Dell Dimension B110. It was originally purchased by my mother whom left it when she moved out of state then given to my younger cousins who fought over it and thus it was returned to me. It been sitting collecting dust for probably 5 years now. I got it all hooked up just to play an N64 emulator and now the USB ports seem to be acting up. The mouse and keyboard aren't recognized despite showing that they are powered on, and the flash drives don't light up when plugged in. I searched online and was able to get them to work only if entered BIOS. After going to the home screen the keyboard and mouse stop working. (Ver. A00 and XP Home Edition if that helps) I was able to get the USB port to work for the flash drives by changing BIOS settings. I also found the OS install disc and used BIOS to ensure that the CD ROM drive boots up upon startup. Now when I get into the home screen, I'm the bottom left corner I get messages showing the keyboard, mouse and USB drive are all recognized hardwise wise but they still do not respond with the exception of the usb flash drives which is useless without an input to access them. I can't even into cmd prompt in safe mode to access the cd rom drive. Odd thing is years ago I remember having to drop this thing off at staples to key network drivers and I believe the underlying issue is without internet I can't download the drivers for all the recognized hardware. (I downloaded the important ones on my flash drive but once again can't access them) However back then the input hardware still worked fine. Any idea on how to install those without another expensive trip to the tech geeks?
