I get on the screen "Please Check The Signal cable" And I get NO BEEPS. HDDS are spinning. CPU fan running. I read through another forum to find out what others have said and tryed and tryed a few of my own. This PC i built hasnt been running yet. So can't see BIOS, nor can update any drivers. Right now I only got the on Board Video card, since I haven't got any PCI express X16 card yet to fit the slot (I may get one when I get more money). Here's what I tryed. Unplugging connector that connects the video card at the back of pc and repluging it, I tryed that a few times. Removing the the 2 RAM I had and tryed one of them at the time. PCI slots are empty at the moment. I tryed to only put the one HDD on my IDE Controler, instead of two. I cleared the CMOS (jumper). removed floppy cable. You would think the MB would beep if there were an error, but it doesn't Here are my spec: ASUS MB P5GV-MX CPU Pentuim 4, 3.20GHz 2 x 512MB RAM DDR 2HDDS (Master: Maxtor 6.4GB, works fine, Slave Maxtor (i think) 40GB) 1 Floppy drive. 15inch CRT monitor (working).
