My D525MW COMM port works properly with windows xp but when I install windows 7 on this motherboard, the COMM port doesn't work at all. Even if I add the second serial port, it also doesn't work. I have test on 2 different motherboard and see this problem on both of them.
Does any one has the same problem? Any idea?
Make sure you have loaded Windows* 7 service pack on your system:
Also, try installing chipset utility for your motherboard model:
I tested both suggested ways. Now my windows 7 has sp1 and I installed the last version of chipset utility but none of them didn't work.
P.S: I have installed some devices same as check scanner, printer and ... to all of it's USB port. Can this issue causes some problems?
The motherboard was designed to work under Windows 7 32 bit operating system; I recommend re installing the operating system but make sure the service pack is included on the disk.
