Getting 4 beeps with memory out, drives disconnected, empty PCI slots. Swapped power supplies and got the same error condition. System was working and quit unexpectedly. Even unplugged the fans and got the...

you posted a mobo number not a PC real name.
its HP 412410-003 HP 442031-001 S775 A/V M/B
that is XW4400 ( I own a mint xw4600 ) simular.
why post MOBO #'s and not true PC name?????????

no MOBO works ever with all memory out , why do that?
just to hear the 4 beeps the manual on the PC
its a HPE workstation in fact not a PC.
the PSU is dead. (or a gross short)
why not test the PSU First with the jumper clip
im reading your manual for you now XW4400
it says. BAD PSU.

Blinks red 4 times (once per
second), then a 2-second
pause, and then 4 beeps

the fans slow means 12vdc is weak as in not at 12vdc.
only 2 things cause that.
bad PSU, or the 12vdc bus is shortred.

more sure
5 beeps is memory dead, low bank.
6 is video bad. GPU card.

the beep code 4 is top priory error
think about that, if power is bad, all else IS
in electronics power is first. and always first.
means at spec.

the test is easy and 3 fold is savvy
1: the jumper test.
2: same as above, but turns on and voltage test all pins.
3: if really pro- a load bank test, puts full load on PSU.

that is why shops with tools waste little time.

strip all things off the MOBO
all drives
all PCI cards and express cards. (all but CPU) CPU dont fail
if the heatsink has not fallen off.
remove all things that can short out 12vdc, fans and drives.
do not run it with fans pulled for more than say 15 seconds
use a voltmeter, turn it on
measure 5v and 12v and 3.3v psu pins. seen in link above
a dmm meter is $20 at warfart. anyone can use one, easy.
the black wires are ground (common) meter black to black.
red meter to the 3 top power pins on PSU jack.

now my wild guess, bad PSU. but I cant strip your PC nor watch you.

Hi, The recommended PSU for your card is 550W.
After you connect it to your motherboard you have to connect a (6pin) PCIE power connector
to the card. Without it the video card will not display anything.

Compaq Presario Media Center SR1750NX - Will not come up. Fan starts on high and stays there. No Keyboard lights flash. No monitor. No beeps. Replaced memory, disconnected harddrive, tested and then put...

the PSU has fan, does it spin and blow.
Seems to me. the PSU is bad. 5/12 is ok but there 20/24 pin connector is way more important that that legacy 4 pin .
my guess is the Cd driver ejects ok.

re-seated memory , i guess. (tried 1 at a time is the way !)
tried in bank 0 (lowest number) one at a time.

the voltage are here, do the bench test on it , all power pins.
see that 3.3v?
unplug it, jumper wire the correct 2 pins
pin 16 to 17 on modern PCs (24pin)
your PSU stays on, but some have really poor power checks.
so the unstated SCREEN , with power on last.
shows, no SIGnAL, no sync, warnings.? (or out of range)
no text ever. on said screen.
what video card is there, or is this onboard video.,
on mobo direct vga jack? yes it does but is there a addin video card there.? count VGA jacks, 2 means it has adding card.
onboard is here.
ATI Radeon Xpress 200 shared video memory (UMA)

I think the PSU is bad, one other way it can go bad is to
incorrectly time the Power _OK pin, timing.(output)
see this many times, this pin tells the mobo power is ok.
if it sticks at ok, the Mobo can not function, if this pin lies.
the PSU tells the mobo power is ok
then if the mobo power regs fail, then the mobo sends
Power_on to false and the PSU shuts down.
in your case the Power_ok seems stuck ok. falsely.
or can be.
the thing to know is the power regulators are in the PSU and the MOBO, and both must be good.
or it will be dead.
we bench test all PSUs
and even swap them , to be sure it is ok,
if yes, ok then the mobo is bad (if all loads removed first)
all hdd,/dvd/cd drive. out. (cables pulled)
all addin cards removed ! all of them. if present (look for them)
all memory out and put back 1 by 1.

Blank Screen, no beeps, New Build

Hi Durmo, your troubles may be the SLI card. If you are using a single 8500GT make sure your SLI card is plugged into the motherboard as a single graphics card. See page 3-9 in your manual. If your 8500GT has dual out puts check both for display. Only one will show you display.
If you have this set correctly & you have tested your monitor on another system (& it is good) yet no display from the system than contact Asus. This board was make in 2007 & is warranted up to 2010. You can do this online or call Asus at 1-812-282-2787 M-F EST. Other countrys click the dropdown menu at Asus home page.

Post if you need more info.
Good luck!

Jetway 867AS motherboard problem

Hi, the problem not your video. It is your memory module, it is faulty. Try another one that is surely working and it should boot right up. Good Luck!
