pci serial port driver dell optiplex 755

Do these machines normally take SO bloody long to boot. Did you ever figure this out? Please email me at Seriously ? sits on a flashing curser at two l-o-n-g intervals, takes about one full minute, then boots into windows XP just fine ? Any idea's ? This page contains the driver installation download for PCI Serial Port in supported models (OptiPlex 755) that are running a supported operating system. Obviously I'm not typing in the right string into google. Unfortunately I lots the link to that forum, and don't know where to start. I also read late last night about a possible fix removing Registry References to old drivers ? And several fixes were found by doing that. 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. But this last ah heck just won't play fair 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.

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) just formatted and re-installed Windows XP Pro. īackgound : Stand alone home PC = DELL OPTIPLEX-755.

I have also done the Dell Website diagnostic several different ways, to no avail -after updating and applying fixes to all of. 'PCI - Simple Communications Controller' - with no driver that will load or work.

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: I have been reading till my eyes are bleeding, and hoping someone can help me out of my dilemma ? Can I resurrect this old thread please ? Just call me Lazarus.
