USB ports stopped working

Specs: Windows 7
I have a slimline hp 7727. I use a wireless usb mouse and keyboard. The operating system is Vista 32 bit.
Recently I connected an external Western Digital drive i have not used in a year or so to move some files. The external drive was operating sporadically. It would not power off, wouldn't remain "alive". When i was moving a large folder containing photos I would get an error about 5 minutes into the move stating that the files were no longer at the location specified. and the move would abort. I ended up unplugging the drive several times and started getting a hardware type error from windows that a defective or failed hardware was connected to a usb port. so i just unplugged the drive.
Later the mouse was not working consistently. but i rebooted and all seemed fine. The next day when i started the computer up I got the error message that the usb had a bad device connected and etc. The keyboard and mouse are non functional. I tried every thing i can think of but still no mouse or keyboard. I tried the ps2 adapter but apparently legacy is disabled. I tried hard wired mouse and keyboard. I still get the same error.
Is there a way to reload the drivers by removing the hard drive and connecting it to another computer ? I opened up the case and I see no obvious loose wire or anything.

Try to reinstall usb driver from device manager. Plug the device then locate the device in device manager and uninstall, restart machine after process is complete. Try the external drive in another working machine.

thank you for looking at my post and making this suggestion. Unfortunately i cant use the keyboard or mouse so i have no way to input or select the device manager. The usb ports are not working. The ps2 ports are not working.

If u can't access BIOS with ps/2 or usb keyboard then the +5v rail isn't working well. Try to swap PSU.

well i was using a ps2/usb adapter for my keyboard and mouse. I found an actual ps2 mouse and it works. I do not own a ps2 keyboard, yet.
For now i put in a USB card where my dial up card used to be. That works for now.
