First PC Build Problem; 2 short beeps

[antonfrompresto]

I have just finished building my first PC and have set everything up and at first the screen turns white then I get one short beep, as the screen blinks black, then a second silent blink and then I get a second short beep. The motherboard is an ASUS P5K Deluxe. Does anyone have any idea what the issue is?; I get nothing but the white screen.

Thanks, Anthony

Alright from the research I have done ASUS use an AMI based bios and the problem is likely to be my memory, more specifically Memory Parity Error in first 64KB block. Would you guys agree that I need to RMA my RAM? I have tried clearing the CMOS and I have tried both sticks of ram individually in each slot.

how about try each stick of the ram at a time? if that dont work, then think about rma.

If you do manage to get into the bios on 1 stick you could check the RAM voltage, try setting it 2.0 through 2.2v and see if you can get them both going.

I've tried each stick of ram individually in each slot and get the same reponse there is about 8 seconds gap between the two beeps and it seems the blinking of the screen does not coincide with the beeping. Anyone got any idea whether it could be anything but the RAM; considering I don't get any picture other than a white screen.

Thanks, Anthony

I don't even see anything on screen; I've tried holding Del when booting and I still only see the white screen.

Thanks. I've already come across that website when researching the problem. Its a bit in depth on that website but on this (http://www.gen-x-pc.com/beep_codes.htm) website it indicated bad memory.

what power supply are you using?

A Silverstone OP750

I don't think this is an issue but is there a reason for the metal spots around the holes on the motherboard where it is attached to the standoffs? Are they grounds or something? Because I used thin cardboard washers between the screws and the motherboard and I'm wondering whether I shouldn't have.

why dont you take the whole setup out of the case, then test it out.

Is that likely to help? Or do you just mean so I can test things with less obstruction. Because I don't really have anywhere suitable for placing the motherboard outside of the case and I have done a reasonable amount of cable management with spiral wrap and zip ties which I'd have to totally screw up if I wanted to stretch the wires far enough to test outside of the case.

if you sure your video card works fine, then try to place the motherboard on top of the motherboard box or any box.

also try a vga cable instead of dvi..

I've tried this with a box right next to the case so I could stretch the cables from the case and I got the same beeps.

also try a vga cable instead of dvi..

Is that likely to make adifference because the video has to go via a vga to dvi adaptor anyway. The reason I ask is because the box for the graphics card is at my Mum's house so I would have to make a journey to get the adaptor.

I'm on a P5K right now.
Before I put it in a case I had it running for a week or so open air. The only errors I got on first boot was a failed overclock, since the bios had set it at at a mad fbs by default. After I sorted that it ran like a dream and has ever since.

So, what slots are your ram sitting in? and what ram is it?
So far anyway, I'm pretty sure the ram is bad. So if you have another ddr2 stick around, try putting that in.

"Memory Parity Error in first 64KB block" can be either a ram or controler it could also be refering to the bios rom . check to be sure bat. and jumper are secure . (when clearing the cmos , did you turn off the psu , remove bat first then jumper , then replace jumper after 5-10 sec. and then replace bat ? ) if thats not it and you are able to eliminate the ram as the problem (see if you can borrow a stick of known good ram . try it in slot 1b first) you could try recovering the bios from the suport dvd or usb flash disk as explained on page 4-7 in the manual but i dont know if youll be able to get that far if mobo wont fully post
i have ran into this 3 times in the past . twice it turned out to be the mobo (controler) but on a p4c800e i was able to fix it by swaping the bios chip . in all 3 case's the ram turned out to be fine .

I've found what problem was and it was simply the monitor. I tried using VGA with the PC and my laptop but it didn't work. I then tried both my laptop and the PC with VGA on the old 17" CRT and they both worked. I have just this minute started installing Vista. Thanks for all the advise guys; it was greatly appreciated.
