So yep, I just finished building a computer and everything went well until there were problems with the hard drive that I was initially going to use. The infamous blue screen came up just after the computer reboots to continue the Windows installation after you format the HD and all and I figure it was the HD. So I grab an older one and it gets far enough to where I'm down to "37 Minutes Left" and then BAM! It's back, that damn blue screen. I forgot what the screen said the first time with the other HD but I don't even care about that one anymore, I'm more concerned with this one since I got further. Anyways the technical information readout is: *** STOP: 0x0000007E and so on and so forth *** portcls.sys - Address and so on and so forth So yea, I'm building this PC for someone and it'd be great if I could receive some help. [EDIT] Oh, sorry, I put this thread here cause I'm wondering if it may have something to do with the mobo or the BIOS or something. Everything I'm building this PC with is new and out of the box save the current HD I'm using.
