i just put in a new (by new i mean reburbished - but its new to me) giga mobo (ga-7n400 pro) and it wont start windows properly. first i got a long beep so i cleaned out cmos and the beep went away. then it would see my hard drives and dvd drives in bios but afterwards when trying to boot, it would do a "ide scan" and find nothing. so i turned off the gigaraid and sataraid chips. the "ide scan" screen went away. now i get a windows didnt start screen with the usual start in safe mode... regular windows boot up. i did regular and safe mode and for a split second i saw the xp logo with a fuzzy blue background then it went out black. the comp then i guess reboots and back to bios back to the windows screen and so on in a loop. no clue what to do. thinking about putting in the windows cd and see if i can maybe fix any window problems it might have - but i cant find the cd. the mobo might be busted but seems to work fine enough to regonize the drives in bios and their sizes and names and everything. any help will be greatly appreciated. much thanks.
