About 5 days ago i purchased a new CPU, Mobo, Ram, HD to finally get around to upgrading my system. C2D E8400 http://www.newegg.com/Product/Produc...82E16819115037 Gigabyte GA-EP45-DS3L http://www.newegg.com/Product/Produc...82E16813128345 OCZ 4-GB DDR2 1066 http://www.newegg.com/Product/Produc...82E16820227289 and Seagate Barracuda 250GB HD http://www.newegg.com/Product/Produc...82E16822148262 I was planning on using my XP Home CD and use the Vista Home Basic Upgrade. Here is my problem, When the pc is initializing XP and just about to go to the screen to format my HD and all, i get A Critical error message, saying it stopped the install to prevent damage to my PC b/c of either a driver issue, a HD space Issue, BIOS issue... (Ill try to get a screen shot of the message) I get the same message when i trie to do the same thing to my older 80GB sata HD ive been using for the past 2 years. i booted up everything off of the older 80gb HD and the preinstalled XP works fine but with some errors due to the hardware changes, to see if the mobo/cpu were fine. Im not sure if the issue is of what components im using and XP's inability to recognize and set up the install... or if i would just be better off returning the upgrade dvd and getting the full version of vista. Or if a piece of my hardware is just fucked. or if my version of XP could be fucked now too... not sure it has 2 or 3 smaller scratched on it, but i wouldnt think that would be the cause anyhelp, Thanks!
