I have a DELL GX270 computer. It has a big problem that needs a solution. Am a programmer and my machine can not detect USB drives. The CDROM drive IDE malfunction so it can not detect CDROM either. Now the hard disk is not detected. The CDROM and the hard disk works well in other computers thus showing there’s a problem with my motherboard. I checked for dry joints or any problems but it still looked fine clean and new. please i need my machine back it has a good speed and its efficient. Please help me… thank you.
