no video signal

I'm casual PC builder and I'm having problem with the system I'm
building.

I have bought P4 2.8c and Asus P4P800 Deluxe to replace my dead old
system. The parts from my old PC are: ATI Radeon 64MB DDR (VIVO), Case
with 350W Enermax power supply, 120GB WD HD.

I have put the system together and tried to boot up. I could hear the HD
spinning but I got no video signal. I don't know what stage it is on in
the booting process.

My monitor appears fine since it displays images fine with a laptop. My
video card should be fine since I tested it on another PC fine. I even
tried an old 3DFX Voodoo 3 2000 and it didn't see any video signal
although Voodoo 3 works fine on another PC.

What could be wrong if the mainboard, CPU, video card, monitor are all
fine? What I'm not totally sure is my DDR RAM, power supply, and even the
new CPU and mainboard. Strangely, my old system had the same problem when
I was trying to fix it after it stopped booting.

Thanks for any suggestions,

Could it be a bad power supply? enermax is a good brand but it's 2 years
old. If power supply powers up and I can hear HD noise, does it mean the
power supply is good?

TIA,

It's almost certainly a bad power supply. The CPU won't attempt to run POST
until power is good. If power is good, CPU will attempt to run POST. If
POST runs OK, THEN the video card will be initialized. If you aren't
getting video or any error beeps (part of POST procedure), then that would
indicate a bad CPU or power supply. As more than one CPU had the same
problem, the power supply is a very likely suspect. Oh, and there are
different voltages coming off of a power supply. If the power supply is
bad, it could still be supplying "good" voltage to your hard drives. And
even with "bad" voltage, it's possible your hard drive might still try to
spin up. So if the HD is making noise, that doesn't necessarily mean the
power supply is good. -Dave

Dave,
Thanks for the suggestion. I just switched to another 400W PSU I bought a
while back (as a backup) and it still does the same thing.

A few observations:
- Press the start button, the fans starts, then HD booted up and stays on
like usual working system. The monitor shows "NO SYNC." This monitor
works with any other PC I have.
- I keep it very simple. One 256MB 333 CL 2.5 memory, one 120GB WD HD on
Primary IDE as the only master drive. One video card, one PS2 mouse, one
PS2 keyboard, and external speaker.
- PSU fans, CPU heatsink fan, and video card fan are all on without any
problems. The whole system is cool.
- I switched between 2 video cards (PCI Voodoo 3 2000 and AGP ATI Radeon
64MB VIVO) and the system behaved the same way. As I mentioned PCI card
worked on another PC after I had problem with this system.
- I took all memory out and the system would beep 1 long and 2 short beep
sound. So, it should not be the memory problem. I switched between 2 DDR
RAM. No difference.

Could new CPU and mainboard does not work with old video cards? Both are
older than 2000. The only thing I can think of doing is: buy a new
computer case with a better and new PSU, buy a PC3200 memory, a new video
card. I originally want to upgrade gradually and only buy it when it's of
good price.

Anything you can think of to fix my PC?

Thanks,


cpliu

Hi: You might want to check the voltage of your card. The Asus users guide
states: "Install only 1.5 AGP cards on this motherboard! 3.3 V AGP cards
are not supported in this motherboard." If you can, upgrade the video card
to an AGP 8X card to get better performance out of your system. There is
an additional 12v power connector on the motherboard - does your Enermax
power supply have that additional connector? I have the p4p 800 with a gig
of pny pc3500 ram, 2.6ghz P4, and just picked up an ATI Radeon 9800 pro on
sale at Best Buy a couple of weeks ago. The system is fast. Let me know
how it goes. Good luck.

myoda, thanks for the suggestion. I did read that part but I couldn't
find any information on my card like the picture shown on the manual. How
about the old PCI card? It doesn't work on that either. My PSU does have
the square connector and the system won't even boot without it being
connected.

I will post whatever I find out.

Thanks,

cpliu

Without a monitor, how do you know the system booted?

You're right that I would not be able to tell what stage it is at in the
proces of booting. I can only guess based on my experience. With my ears
close the the HD, this is what I hear after pressing the start button:
1. power on, all the fans (PSU, CPU, video card) start right away
2. Within 1 second or so, HD powers up with nnnnnNNNNN kind of starting
noise.
3. For another second or so, HD makes noise like it's reading something,
de, de, de,
4. Just the normal HD spin noise.

What I heard was just like a regular initial booting stage of any PC. I
couldn't tell if it's stopped at BIOS, or because the HD has Windows 2000
installed on anther Motherboard, Pressing the keybard does not advance
further (which I can judge by HD reading sound). Pressing the start
button for 4-second or so shuts the system down. I couldn't tell if reset
button works and it's likely not working.

Thanks for the help,


cpliu
