Just got finished assembling my first new build. Motherboard light is giving me a green, PSU working well, Fans in case and on mobo are all fired up, but I get no Bios option when booting up. Is there a possibility my Ram is not compatible with my motherboard and would this be giving me this type of Error?

I bought a P5N32-E SLI Asus Mobo.

Memory is Corsair 4GB TWIN2X5096-6400C5DHX G.

I do not see my mobo being supported on this particular piece of Ram when I go to Corsair's website. I am thinking this is the error, or a bad CPU.

These are my only two guesses....please help!

Thanks in advance!

Try only one stick of ram until you get the thing running. If one dont work try another and try different slots.

Do you hear any beeps?

If it boots on one stick of ram you will need to set the ram defaults manually in the bios. It probably isnt giving it enough volts on default.

I hear no beeps, and I don't even see on the Mobo any type of onboard speaker. It has an audio card that it came with that I will try to plug speakers into, but up to now I have not heard a single beep....not to mention the Keyboard isn't even registering and I get no BIOS menu.

Not sure if it's the CPU, the Ram, or just something I didn't connect correctly?

Did you retry with only one stick of ram and try each one seperate?
Each time you change something shut the psu off then back on.

Does your case have any wires labled speaker on them?

Or did your mobo come with a little black round speaker?

Case has no wires labeled speaker, and the board it self did not come with one :(  I tried what you had mentioned above, still no luck :(

Youll need to get one. There has to be a spot on the mobo to plug a tiny speaker into.Usually Asus sends a speaker in the box. And all the cases I ever bought have had them.

Do you got the 20/24 pin and the 4 pin atx connectors plugged in?

You try the ram idea yet?

I tried the RAM idea, not the issue it seems. I *think* I have the 20/24 Connector plugged in...I do see at the upper left corner of the Mobo there is something that says *12V ATX* That I have nothing plugged in to, could this be the problem?

ok, it has 4 connecters, but it looks like it has 8 total with 4 of them capped off, does it make a difference what I plug into this with my PSU?
December 17, 2007 1:14:54 AM

Your psu will have a 4pin or 8 pin plug either will work.
December 17, 2007 1:15:31 AM

If you only have four plug it into the one thats not capped. If you have an 8 uncap it and plug them all in.
December 17, 2007 1:20:56 AM

I plugged them in with the 8 pin, now my Keyboard is recognized, but I'm still not getting anything booting up on my monitor. Still no Bios Option, and I read the manual clean through...no speaker, and I don't see anyplace on the board for a speaker to be placed. Do you think I should contact Asus support at this point?
December 17, 2007 1:22:41 AM

No. Unplug PSU from wall and try again with one stick in dimm 1 if no go try one stick in dimm 2. Unplugging the power supply might get you going. It resets the board somehow.

YOU GUYS ROCK!!! Up and Running in my BIOS, Thanks for the help, I'm sure I'll be back again when I'm stuck!!! :)

Congrats man. I'm glad to help. I take donations to my Paypal. lol.
What CPU do you have?
December 17, 2007 1:43:36 AM

lol, I have a Duo Core, Pentium 3G's. Next question.....BIOS tells me my fan is running too slow, but it shows the Temp in the Bios Menu of 29 C. Should I be concerned about this error? I have a mean after market fan, and it seems to be doing the job.

Thanks
December 17, 2007 1:45:14 AM

Sorry, not Pentium, just Duo Core :D 
December 17, 2007 1:53:01 AM

Whicn one 6600 2180? any of the others? As long as the temp is 29 your right on.
December 17, 2007 1:54:57 AM

Yeah, says it's running too slow. I'm running the E6850 I believe is the model. Should I disable this warning in the Bios menu? Of course the CPU may heat up once I start installing and running more software.....
December 17, 2007 2:03:54 AM

I'm sure its fine. I'd load windows. It will shut off if it gets to hot but if its still 29 its perfectly fine. Once you get windows lets crank up that cpu a bit.

If you dont mind the noise you can turn C1E and EIST off and i think its usually speedfan or something off which will make you CPU run at full speed all the time and fan run full speed all the time this will stop the fan errors also

Should I really be focusing on tweaking the BIOS now or should I just install windows at this point?

Thanks again for all your insight....
December 17, 2007 2:26:59 AM

Do windows and make sure all is well then I'll help you tweak.
You gonna use Vista or XP and how big is your HDD.
December 17, 2007 2:38:55 AM

I am doing XP (Better benchmarks for Gaming right now from what I hear) 32 Bit OS, and I have 2 HD's - One Raptor 74 Gigs, and one Western Dig, 320 Gigs for Storage. I'm installing XP now, wish me luck!
