PCI Serial Port Driver problem

HP Recommended
Compaq dc 7800 small form factor
Microsoft Windows 7 (32-bit)



I have a desktop HP COMPAQ  dc 7800 small form factor pc. On device manager the PCI Serial Port shows that driver is missing, also my Wireless Network Card is not working correctly, it do not find any domain, it shows the red X. The same with a Wireless USB.

I connected the PC through a Lan cable with Internet, then i searched for updates, but there was not any update. When I select propertis shows the ( code 28 ) and the location ( PCI Bus 0 , device 3 , function 3 ).
