Thanks so much for these tips! I've been trying to figure this out for days and keep going in circles. None of my usb flash drives will open on my new Lenovo laptop unless I go into safemode. Then, only the ones connected while in safe mode will open when I restart but if I shut down the system I'm right back at square one. I know its not the flash drives because they open fine on my desktop. I'm really hoping I don't have to restore to factory default since I can't use my usb external hd all my other back ups are on. I haven't tried it yet but I'm pretty sure that's when my issues started. The first time I backed it up it ran fine but I hadn't connected the base and later learned I had it in the lowest powered port. Since then my external hd won't do anything with I try to do a back up AND I have to go through this huge ordeal when I want to open files from a usb drive. All my other usb devices work fine, it seems to be isolated to storage devices.

I guess I'm just going to go down your list of fixes and if that doesn't work I'll have to do a system restore. I must say that I'm not very happy that I didn't get my own OS discs with my new computer. Its partitioned on my hard drive which I think is extremely careless. If I own the key why not just give me the disc? Maybe its just me but I've never had so many issues with a brand new computer. I'm a student and really need to fix this issue before classes start in the next week. Internet explorer crashes a lot as well so I don't know if that's related but I've never really liked IE anyway.

Thanks so much for the info, if you have any suggestions please let me know.:)
