bsod,memory probs

[neverman]

Here's my problem,first was realizing that my board didn't come with any external com or printer ports,so i bought a Vantec docking station which gave me my com and printer ports(could never get the printer port to setup)so my real prob is when I use the com port to do certian things like programing cards, half way through i get the bsod,with the error of memory placement is wrong,I,ve run memtest for about 4 hours no errors,so i'm guessing this has to do with the usb to com port setup,tried setting it up on different coms no go,use it on my laptop works perfect,could this be an xp thing or this just won't work with my setup
