New build not booting

Hi,

I recently have bought some new components to build a new computer
(rescuing a hard drive, CD-RW, DVD-RW, sound and graphics cards from an
old computer)

My problem is I have put it all together and the computer wont boot.
All the case fans and CPU fan are going, the LEDs light up (power full
and the HDD faintly) But there is no video signal out. I have also
noticed that the DVD drive powers up but the CD drive does not (tried
swapping the power plugs around) and I am now at a loss and need some
advice. I have only ever built one system up before but that was
relatively simple compared to this.

The components are an Asus P5P 800 PE motherboard, Intel Pentium D 930,
Maxtor 120GB HDD Drive and a 48oW PSU


Many Thanks
Rich.

remove all but the basics............then try start up.

if it fires up add 1 bit at a time..........until you find the culprit.

First check the basics, e.g. see if any extra motherboard standoffs
are installed in the case. They can cause shorts/grounds when they
contact the underside of the motherboard. Also make sure you
have a power plug to your video card (if it has one), a plug to your
CPU power socket (if it has one) etc.

Go right back to the basics, remove everything except
the cpu and see if it will beep complaining about no ram.

If it wont, check if the cmos reset jumper is in the reset
position and reset the cmos if its in the normal position.

If it does beep with just the cpu, add the ram and
see if it will whine about the lack of a video card.

If it does, check that the video card is compatible with that motherboard.
Most likely it isnt.
 
You may not be able to confirm this easily, but when I was putting together
my system, I did some reading that suggested that with some boards, you have
to make sure they're flashed to the most recent version to work with the
newer processors. So I had the company I bought it from flash it before I
took it home, as I figured it would be kind of tough to flash it if I didn't
have a processor that worked in it.

For some reason, the P5P800-PE board isn't listed on the Asus website, so I
can't see what BIOS version is required for the 930D processor. Not that it
would matter too much, as you probably have no way to find out what BIOS
version you have anyway... :)

Yes it is.

Except that's the SE, not the PE.

They have a CPU Support page on the Asus website, and if that IS the board
he has, then it will depend on the revision of his D 930 processor,
apparently.

Sometimes there is a sticker on the flash EEPROM that states
what version of BIOS was flashed at the factory. You can use
that, if the sticker is there, to figure out whether the
CPU purchased, and the motherboard in hand, will work together.
If the BIOS is not recent enough, in some countries Asus
will ship a replacement BIOS chip for a fee, or a company
like badflash.com can do that for you too.

Most of the recently shipping Asus motherboards, will be in
this master list. I don't see a P5P800 PE listed there,
but there is the SE (second edition of P5P800). The
P5P800S, on the other hand, uses 848 chipset, and has
single channel RAM support (no dual channel), so I suppose
the "S" there stands for "sucker".

You can also navigate around the FTP site, in search of
motherboard names, if all else fails:

Everything that was said earlier are good starting points. For this
issue, I would reseat both the processor and memory and if that does
not work, I would try a different power supply.
