I think I must have a poltergeist.
I have a minimalist machine on the bench; Gigabyte H55M-UD2H motherboard, Intel i3 540 running at 4 GHz, 8 GB of RAM and a single card -- an MSI HD7750 graphics card. The OS is Windows XP with all updates and service packages through the end of Microsoft support for Windows XP. It has been running for maybe a year. Recently it began showing on bootup: New Hardware Found, a PCI Communications Controller. Nothing has been added or removed from the machine in a long time. What ever driver it is expecting is not on the Gigabyte CD. Device Manager shows a yellow question mark beside a PCI Simple Communication Controller. Clicking on properties gives:
Ven_8086&DEV_3864&SUBSYS_38641458*REV_06
I cannot identify the vendor on net. The message does not refer to the MSI graphics card, so it has to be the motherboard. I have reinstalled the latest Intel drivers from the net (after the problem appeared), but the Found New Hardware message still pops up on each boot. The machine goes on internet and on the LAN with no apparent difficulty.
Any idea of why it has sudenly started detecting new hardware when no changes have been made -- nothing new connected by cable and no new card plugged into the motherboard? No BIOS changes for many months.
Thanks.
