I installed Windows 10 Pro, 64 Bit OS (with a 250GB SSD).  Thankfully I had only 2 errors showing in "Device Manager"!

Even with the 2 errors, everything still appears to work OK!  After 10+ hours of operation the CPU is just 96 °F.  I also installed a 2 port HDMI card before the fix (listed below) and it too was working fine!  Here is the first error:

PCI Simple Communications Controller:

VEN_8086&DEV_2E14&SUBSYS_027F1028&REV_03
PCI\VEN_8086&DEV_2E14&SUBSYS_027F1028

(Also reported as):

PCI\VEN_8086&CC_0780
PCI\VEN_8086
PCI\CC_078000
PCI\CC_0780)

Odd but the only place I found a 'Fix" for this is on a HP Site!

PCI Simple Communications Controller Driver X64 Drivers

After installing the Drivers that error is gone!  I'm still hunting for a Intel Core 2 Duo E8400 @ 3.00GHz Driver or fix!

Hope this helps you!
