Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor - Retail
Asus P5N32-E SLI PLUS LGA775
Gigabyte 512MB 8800GT PCIe
OCZ StealthXStream 600 Watt Gamers Power Supply Unit - OCZ600SXS-UK
CT2KIT25664AA667 4GB kit (2GBx2), 240-pin DIMM (this is the correct memory module i used crucials tool to get it)

I havent even bothered trying to connect anything else to this until i resolve the current problem. I have tried everything, replaced the motherboard tried one memory stick at a time and still nothing. I turn the system on and the fans work everything lights up but my flat screen just goes back into sleep mode and no beeps at all.

(when i had the harddrive fitted it had a red light next to the power button on the case)

I know if there isnt any beeps its failed its "post" and what i got from other forums is it maybe the bios needs upgrading but the asus website is down and how would i update the bios if the screen isnt working!?!?

I have to use the graphics card to put the vga socket in using the dvi adaptor as there isnt a vga slot fitted on the motherboard, i have checked and triple checked the connections everythings fitted fine.
 
I would have guessed that maybe the motherboard didn't support your E8400, but the product page on Asus' website claims to be "LGA775 Intel® 45nm Processor Ready"

Try unplugging the power supply, then removing the backup battery for a few minutes. Clear CMOS using the jumper if there is one.
 
From previous posts it sounds like the mobo supports the E8400 (45nm), just check the ASUS web page and make sure you have the most recent BIOS. Then to be on the safe side unplug the PSU and use the "clear CMOS" jumper to reset your BIOS and give it a try again. Don't forget to wait 15 mins to be on the safe side before putting the boxen back together. (replugging PSU, changing "clear CMOS" jumper back to normal) :)

If all else fails it may be a short (of course everything else being equal, like knowin' the parts you're using are good, PSU,VGA, RAM, monitor, etc ;)) so take the mobo out of the case completely, lay it on some non conductive material, no metal contact at all (cardboard, etc, not the anti static bag). It may be a good idea to add spacers under the board and a fan blowing on it so air can get under the mobo. (non conductive, the mobo may get too hot)

Just have the monitor, PSU, VGA card, 1x stick of RAM hooked up, power on with a screw driver and see if you've got video, if not try reseating the VGA card and all electrical connections to the mobo (the mobo BIOS should appear on you're monitor). :)

Common sense tells you to make sure your VGA card, PSU, RAM and monitor are working correctly. (swap out the parts to "known" good parts or another working boxen if you have any doubts) :)

It goes with out saying "ALWAYS" wear a "anti static" wrist band or at the very least ground yourself on a "cold" water pipe, etc.

Good luck, I have had a few "shorted mobos" in my day. :rolleyes:

Edit: The reason I said "not the anti static bag the mobo came in" is I've read several articles on the "Net" where any anti static bag is not worth a "fart in a wind storm" if the parts(s) aren't in it and sealed up. I always try to error on the safe side :p
 
if it isn't beeping then you have a problem. It could either be the PSU or the Motherboard.

Make sure the voltages coming out of the PSU are correct. If the voltages etc are correct that means it's your Motherboard.. If not it's your PSU.

I'm leaning towards Motherboard. the motherboard should beep if it has power and doesn't detect a proper CPU, RAM,Video Card. Since it's not beeping I think your MB is jacked.

Could be the processor. It happened to me once. All my fans spun (even the ones attached to the mobo) and the hard drives spun up, video card worked in another machine. Replaced the processor and I was set.
 
Thanks for the replies this has possibly been the most informative forum iv used and iv posted in loads to get this problem sorted! Going to print this out although im pretty sure the manual that came with it (asus should get a prize for the detail they put in it) might be able to show me how to do this anyways.

If its the mobo then i wont be buying from asus anytime soon as this is the replacement from the old one. Gonna do everything that was recommended.

How do i find out how much voltage the PSU is using?
 
In addition to testing the PSU/mobo, if you have another CPU available I'd suggest trying it; your board may only support 45nm processors after having a BIOS update
 
Most definitely check the mobo for any "shorts"and also (D'oh, I forgot) check the PSU. (thank you above posters) ;)

I just had a new folder with a new setup (E6600, GF7100PVT-M3 mobo, Antec 400w PSU) after changing the PSU works flawlessly now. It was kind of like yours, "all the lights were on and nobody was home" (everything spnnin', no boot) :D (bad PSU) :(

I've had many chips in the past, especially the newer C2D's (E6300, E6400, E6420, E6600, Q6600), and I have NEVER (knock on wood) had a cpu failure and I'm always playin' "musical cpu". ;)

Moral of the story: check every freakin' thing before even suspecting your chip being bad. Unless you dropped it over 5 feet onto a hard floor, were in a levee broken flood, fried it (over volting, static elect, no HSF, etc), your dog, cat or kid slobbered all over it or some other, known to you calamity, chips are tougher than you think. :rolleyes:

Please keep us informed. It's always good to hear solutions to problems with our boxen. :)

Edit: Oh yeah, the only way I know to isolate any booting problem is : (1 with mobo out of case, on non conductive material, no metal, etc touching it ,(2 cpu and HSF , known good cpu, checked in another boxen, (3 PSU (one that has been checked in another boxen), (4 video card (known good card, checked in another boxen), (5 one good stick of RAM, switch slots periodically and try each slot (known good RAM, checked in another boxen). Sans everything else, you just want to get to the boot screen. Make sure the CLR_CMOS jumper is in the correct position and any other jumpers (check the users manual, some mobo manufacturers have been known to ship the mobo jumper CLR_CMOS in the CLR_CMOS mode, saves bat ? :confused:)

After doin' all that crap and still no boot screen it's probably the mobo :eek:. If you get a boot screen return the HD, DVD, etc one at a time making sure the BIOS is is the default setting ;)

Man, I hope this helps a little, please keep us informed and if I "goofed" up anywhere, please someone inform me. I don't think anyone knows it all and all we can do is share experiences on this great forum. :)
