Can I resurrect this old thread please?? Just call me Lazarus.:-) I have been reading till my eyes are bleeding, and hoping someone can help me out of my dilemma? I have tried all the advice in other threads, (bits relevant to XP Pro) and still have the 'Other Devices' flagged in the Device Manager as: 'PCI - Simple Communications Controller' - with no driver that will load or work. I have also done the Dell Website diagnostic several different ways, to no avail:( -after updating and applying fixes to all of.NET runtime updates etc etc etc.... Backgound: Stand alone home PC = DELL OPTIPLEX-755. Just formatted and re-installed Windows XP Pro. Standard Intel Core Duo E6550 @ 2.33 Ghz / 2gb DDR2 SDRAM (PC2-6400) / Graphics=Intel Q35 / Network= Intel-82566DM-2 / 150 GB Hdd (Bios is old A12) What I've tried >> Obtained the driver pack as mentioned here in other threads, and individually installed every driver for all of the unknown hardware one by one. But this last bugger just won't play fair:-) Perhaps I installed drivers in the wrong order??? There was two of the above unknown 'PCI simple communications controller' entry's, but one easily installed with one of the above Dell drivers. I also read late last night about a possible fix removing Registry References to old drivers? And several fixes were found by doing that. Unfortunately I lots the link to that forum, and don't know where to start. Obviously I'm not typing in the right string into google. Can anyone please help?? Both are under the Chipset driver category on the Dell Resource CD. Optiplex 755 PCI Serial Port Driver?? I just installed windows 7 on a Dell Optiplex 755. Cheers, Paul. Do these machines normally take SO bloody long to boot. Sits on a flashing curser at two l-o-n-g intervals, takes about one full minute, then boots into windows XP just fine??? We have a lot of these in our environment, after installing the Intel chipset drivers, Dell Utility Package off the dell site all device drivers would normally be fine. Though with some of them we have to patch the NET framework to version 4 before it would work properly. Put the service tag into the dell site and download all the driver packages again. As for boot times, they don't normally take more than 30 seconds to a minute to boot if fresh install. If they're already on a domain, perhaps check your group policies. If not on a domain, check the event log in case something is causing a problem. Hope that helps. I guess these are security or intel amt devices. TPM has been deactivated in BIOS? I've also found a lot of incomplete Dell driver download pages for certain S-Tags. Look for additional drivers by modell name. You'll be surprised how much more dell downloads has to offer. There are different opinions on this, but for my cases the dell support hotline has had always a solution for me Other options are DCSU = Dell Client System update or if you can find it, the 'Dell Security Device Driver Package'. Download and install Everest () In the section devices/physical devices AFAIremember there's and option to see what it is. Use that information to google/download the relevant driver.... On the other hand. Why are you so persistent on installing it? Is something not working?:P Any chance for oem dvds that came with the desktop? They shoud've all the drivers. The one and only rule of thumb - don't fix things that work.. EDIT: If it's a DELL machine you should have a service tag code to get to the proper drivers page on Dell's website.
