PCIE Netcard GUID Problem

[xiachenyan]

I uploaded a pic regarding my netcard problem, I used to have a PC with its originial netcard detailed with the UNKOWNING GUIDs, yet i brought a secondary netcard put on my mother broad, the secondary netcard started without these unknowing guids, somehow after several days these freaky GUIDS came out again. can anyone tell me what are these numbers and why are these GUIDS instead of normal descriptional word? I care about it because these GUIDS can slow down my internet connection speed and i have no idea why.

GUIDS means: {3AB22E31-8264-4b4e-9AF5-A8D2D8E33E62}[1]-[25]

Sincerely
