I had a corrupted hard drive and removed it installed a new hard drive 120GB and inserted the original CD for this computers OS and Drivers, but for some reason this one device is not functioning properly and shows the YELLOW ?... Everything on the computer seems to be functioning properly. I haven't checked the PCMCIA Card slots as I generally do not use them. Otherwise it seems to be functioning at 100% but I would like to clear this up. I did uninstall the device but it pops up when I restart. I did the reinstall driver, roll back driver and update driver all to no avail. I also went to the support site for HP but cannot find a driver that sounds like it would be for this device! Any help would be greatly appreciated!
