I can't remember exactly how this happened because it's been a cascading disaster. It started with my efforts to uninstall Crashplan. In the course of this I unplugged one usb drive (I have 6) from a hub while it was on. At the time everything seemed ok, but it was not the case once I shut down and rebooted.
I have usb 2 ports and usb 3 ports along with an old usb card which works fine for a laser printer, scanner etc.
Now in a situation where not a single usb drive is recognized except for the yellow exclamation in device manager. Drive properties all say "A driver
(service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)". After researching this and talking with Asus, I was told to reinstall the NEC USB drivers
,and to reinstall the Intel Chip software. When this didn't work I followed instructions on the net and first uninstalled the devices, shut down, and rebooted letting Windows find the "right" drivers. Windows appeared to replace the same drivers in device manager and continues to be unable to recognize a single USB 2 or 3 drive whether it is plugged directly into the machine or into the internal card or either external hub. At the same time, all these usb ports recognize my mouse, my keyboard, my laser printer, battery backup and more.
I've tried the uninstall, shut down and let windows install several times and Asus quickly lost interest and offered to RMA the board which is not worth the trouble to me given that it is already about 3 yrs old.
I can't even use a backup because no external drives can be read.
Not sure where to begin but I really need HELP! I've no way to backup, store photos, use the computer with safety. I'm quite sure this is not a function of a virus or malware as I'd just run Eset and MBAM the night before. And the things that work, work perfectly.
I have a strange error in the event log (several times) - don't know if it's related to the "service" that was stopped and therefore the drives don't function, or not. It says: "Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected."
Can someone suggest where I might begin. I have a restore disk from 2 1/2 years ago when I bought the computer but that seems rather drastic since I've added 4 drives, 16 gig of ram, an SSD and on and on.
Asus P6x58D Premium, Win 7 Prof SP1 64 bit installed a few months ago on the new SSD. 24 gig of Ram and lots of hard drive space. C is a Plextor 5P 256.
Thanks for reading this long saga of woe.
