[QUOTE="328ifun, post: 1619991, member: 337571"] Please help me find a solution guys, I would really like to have this up and running by this weekend. I want to upgrade it from the quad to 8 eight core setup... Heres a more detail description of what happened. 1. I unplugged the PCI-E USB card that had supplmentary power via a 4-pin Molex 2. I installed a 650Gt without the supplementary power to see if windows would recognize it - it didn't. But at this point it still regonized the Hard Drives/Booted fine. 3. I then used the 4 Pin Molex from the USB PCI-E card and spliced it to a dongle from a PC power supply that has (2) PCI-E 6 Pin video power adapters. 4. I connected the 6 pin to the video adapters and then got no boot. 5. I then removed everything that I had done and put everything back exactly the way it was, still no boot nor does disk utility see any of the 4 hard drives I installed. - I also cannot hear the mechanical hard drives turning/spinning. - Sometimes the CD rom shows up in Disk Util, other times it doesnt. Any ideas? How should I approach this? [/QUOTE]
