| 752206 | 2009-02-28 11:35:00 | you using a graphics card? if not check it has power. usually they scream at you if it doesnt but on the off chance check it also the psu seems like a bit of low wattage for what your using, depending on graphics of course |

| 752207 | 2009-02-28 12:15:00 | Check BIOS jumper is not on the "Clear" position, or it won't boot. Nothing shorting out under the motherboard? Does the current BIOS revision support your CPU? Are you using the onboard graphics or a card? |

| 752208 | 2009-02-28 12:56:00 | Jumpers in default position for bios. Mobo is currently on bench/cardboard. My understanding was it's supposed to work right out of the box... This page should tell all: support.asus.com PRO&product=1&os=24 Printed on the board is rev. 1. 02G Otherwise there's no display to check. Using onboard graphics. PSU is rated 510w max power & 450w output power: www.acbel.com Thanks. I'm no closer to solving this here. Going to try another bios reset. Here goes... |

| 752209 | 2009-02-28 13:38:00 | 125watt CPU is pretty high.. PSU rating in watts mean nothing. What you need to look at is the current on each rail According to yours, it's 18A on each 12v rail (and there's 2 of them). Now the CPU will be on one, and the other will be connected to something else Not heard much about ACBel but they're supposed to be OK. BUT can you try it with something else like an Enermax? Got the 12v AUX connector plugged in? All CPU are supported past board rev 1.00G and yours is 1.02G so that's fine. But you will need BIOS v0217 or newer. Does onboard graphics share system memory? Do you need a module plugged into a certain slot to allow it to find the memory? Some onboard graphics will only work with RAM plugged into slot 1 for example. |

| 752210 | 2009-02-28 20:15:00 | True, go to the ASUS site and see what BIOS is needed. If you need a later BIOS, you'll have to go back to the shop, and ask them to put a lower spec CPU in, flash it, then put yours back in CPU's are here (support.asus.com) |

| 752213 | 2009-02-28 20:37:00 | Yer I do, thats why I said true. And Tbirds's link didnt work. Which is why I gave a link that works |

| 752214 | 2009-02-28 21:03:00 | Remove all the memory - fire up the board it should beep like crazy indicating no RAM. If it doesn't and every thing else is OK the board may be DOA - had an Asus board a few weeks ago like that. |
