What all do you have plugged into USB? Do you have the USB devices plugged into the front or back USB ports. If you are plugged into the back, what color are the ports?
Since it works in the bios, but not in windows, it's most likely a driver issue.
Have you checked device manager to see if there are any problems?
Have you gone to control panel and the system hardware manager to remove the drivers and let Windows "rediscover" and install?
Can't access the system now since keybd & mouse are USB
Picking up PS2 devices tonight so will try that first
I think it's got to be drivers since keybd works in BIOS
USB devices (wireless kb dongle, wacom tablet/mouse combo) all plugged to rear.
Will check later colors of ports as I know some are dual USB/eSATA
Will post later tonight with more details
Thanks to all
Note: Am using Synergy software on 2 computers networked to use single keyboard for 2 systems/2 monitors.
All devices not working are plugged directly into USB troubled system
This setup has been working GREAT for 2 - 3 months
When you move mouse off 1 screen to the other you are now working on the other computer
Make sure the Wireless keyboard and mouse Receiver is plugged into one of the black ports on the back. Also make sure you unplug the other USB devices. Turn on the system and then select F8 during boot process till you get the Windows boot options menu. Select Safe Mode from the menu options and then see if the mouse and keyboard allow you to enter either your standard account or the Admin account in Safe Mode. If not see if you mouse and keyboard have a connect button on them along with the receiver. If they do then hit the connect button on the receiver first and then the mouse and keyboard. Then check to see if the mouse and keyboard are working in Windows. If they are still not working then use the PS2 mouse to uninstall all USB controllers and root hubs. Then reboot the system into normal mode and wait for them to reload. Let me know if that still does not work.
Yeah, try safemode. That will get around any driver issue if that is the cause, and you shouldn't have any issue getting into safe mode since the boot selection menu is accessed before drivers are loaded.
One other thing, since you are using synergy, have you tried plugging the keyboard and mouse in the other machine and then use those in the machine that is not working properly? That would be another possible work around without needing to go buy a ps/2 setup.
I'm not at the system now but from what I remember this morning, F8 got me to the safe mode selection options but at that piont the up/down arrows were not working to make any choices.
I did remove the keyboard dongle from the problem system and plug it into the other system to check email. And I also had a travel USB mouse plugged into that system as well. I did not tink to see if Synergy would allow access to the problem system
I just found an unused PS2 mouse and keyboard at work so I won't need to purchase.
Will post later when at home to report results.
Here's an update:
Had to use the PS2 devices to access the system. Went to device manager and all USB host controller listings had exclamations. Only the 2 USB 3.0 devices had no issues.
I right clicked and uninstalled each one and then rebooted. All items were re-recognized and exclamations were gone. I checked the USB devices were working and they were so I packed up the PS2 devices and put them in my car. Came inside, had a beer, rebooted the system for kicks and everything is not working again. All USB devices have exclamatiuons again in device mgr.
Also I got a Windows activation message popup when rebooted.
It could be a motherboard issue, but it can also be that you have a virus or something in your system, causing this issue. I would first try a complete reformat and reinstall of OS and programs. Remember to deactivate Adobe before starting that.
