Answer» Ive just built my own first COMPUTER i and im using crossfire ati 3870s X2 when i turn on the computer the BIOS and CD-Rom for Windows XP boots just fine but no matter if i go into the bios or the XP startup after about 2minutes of running the computer the monitor GOES to a no signal mode. ive tested it with 2 monitors and 2 cables that i KNOW work. Im not truly sure what the problem is im THINKING it might be the powersupply which is a 600W coolmax i know that the RAIL for the 12V is at 18A where the graphics card recomends 30A i know this is a problem and i intend to fix it but im not quite sure if thats the problem or not. help plz i would like to finally play crysis and anyother game without super lag or bad graphics i want my baby aworkin!
