The box says that it puts out 800w continuously and 850w peak. so once i get everything nice and hooked up i fire up the computer. all the fans spin up, HDD light on, and Mobo light on, however, the screen stays black. The motherboard then lets out 3 long beeps then nothing. I tried reseating all the power connectors, RAM, pci and pci-e connectors but i dont know whats wrong. I checked the intel website to see what the 3 beeps meant but they didnt really give a clearcut explanation. Does anyone know what the heck is wrong?! here are my spec's Intel D975XBX2 Extreme series motherboard Intel Core 2 Quad Q6600 @ 2.4ghz Ultra Chilltec TEC CPU cooler XFX 8800gt 512mb alpha dog edition Seagate sata HDD @7200rpm x2 1gb kingston ram @800mhz x2 1gb corsair ram @800mhz dlink dwa552 wireless network adapter x2 pioneer DVD-RW IDE x2 120mm fans w/ LED x2 250mm fans w/ LED Keep in mind that this computer worked fine with the 650w corsair psu and i have changed nothing other than the psu since then. I bought this psu from tigerdirect if that makes any difference. |

Actually, mobo NEEDS a keyboard to boot. But, you can also desactivate keyboard check in the BIOS now... | ||

The only thing i've done since this problem arose was install a new power supply. i think it might be a faulty unit"/ any other suggesitons guys? |

If you can deactivate it, it means it doesn't need it. Which is what Perry was getting at. The only motherboards that 'NEEDS' it are very old. I haven't seen any modern boards that actually enforce the keyboard requirement. | ||

Funny how mine, a Gigabyte P35-DS3R which 3 years old, needs a keyboard by default... By default, a mobo will need a keyboard. In the BIOS you CAN desactivate that check. This is by my experience. This post has been edited by Lebon14 on May 22 2010, 06:13 PM | ||

Can you believe the idiots I deal with? Group: Advanced Members Posts: 1,190 Member No.: 6,608 Joined: Apr 11th 2005 Location: Update Profile | Three long beeps with an Intel board can either be memory OR video card. Check to see if you're giving the correct voltages to the memory. Some RAM do need an increase in voltage... Try using only the Kingston first with stock voltage from the BIOS. I had the same board before and it is picky with memory and voltages. |
