So my computer was working fine until my motherboard crashed on me, i RMA'd it, but meanwhile i leant my HDD to a friend (he deleted everything and started over) , he used it for a while before he ordered his own, now i got it back and my mobo. Before RMA'ing my mobo i had a deskjet 5550 and an external seagate HDD that worked just fime, now when i attempted to install driver software automatically it couldn't find any, so i did manual browse to :C//Windows/ and :C//Windows/System32 and it said found them but couldn't install? this was a while ago, and yesterday my ethernet controller was being stubborn and could not find the network, so i uninstalled it only to attempt to reinstall the driver and find out it can't? Plus my computer has been seeming to acting really slow when i try to open/save files lately, and many programs have been freezing and when i taskmanager --> end process, it doesn't respond and takes like 30 sec to 5 min to close
