Missing driver PCI Serial Port

Question

I have tried to resolve a yellow exclamation icon in device mgr, pertaining to other devices/pci serial port. I have a Dell OptiPlex 755 running Win 7 32 bit. The missing driver has the attributes in the details/ hardware ids of the device  of PCI\VEN_8086&DEV_29B7&SUBSYS_02111028&REV_02 I have run the DELL diagnostic tool and also inserted my service tag number.   The tool diagnosed 3 chipset drivers to update, I downloaded and installed these, rebooted, but the same thing happens. I also went and uninstalled the 'device', but on reboot it installs it again, but neither windows or online can find the device. In device/resources...it says pci serial port  resource settings  This device isn't using any resources because it has a problem. I have searched online for a driver, but my anti virus tell/warns me they contain malaware and/or to get the driver, you have to install a number of other unwanted programs to do so. Can anyone help me to resolve this issue? Many thanks

The three chipset drivers should be installed in order after Service Pack 1 and Dell System Software for correct functionality.

The VEN/DEV reveals this driver - 'Intel 82Q35 Express Serial KT Controller' - but a quick search showed a couple of results that relate to the Dell OptiPlex 755 and people sharing your difficulty in finding it. This thread popped up and the last post maybe of some use. http://en.community.dell.com/support-forums/desktop/f/3514/t/19246390.aspx

Thanks for the posts to me in help.

From following some of the previous info, I got to here.

http://ez93.com/devices/Ports/Intel/82Q35ExpressSerialKTController/#PCIVEN8086DEV29B7SUBSYS02111028

I loaded the top one and installed it to the Dell.

The exclamation mark has now gone.

Many thank you's...appreciated
