My hp compaq dc5100 mt on boot would have a series of 5 long beeps, paused for a few seconds then start over again. This went on for a series of 5 times, so i cleared cmos buy unplugging power, holding...

wow its telling you what is wrong. nice no?
the HP manual covers this, as does all HPs ,ever seen that?
there is no lack of answers nor lack of tests, not EVER.
any A+ Certified tech can help you,, it's super easy. that.
DC5100-MT is the real name with dash
and MT means mini, not SFF. ok got it.

ill first do age then spec, to see what this is.
its old for sure with Compaq logo, (relic in my book)
did you replace that old BIOS CMOS coin cell yet/.?
they dont last this long, clear?
desk top PC,

what is this thing>?
Holding cmos button.
there is no such button, only power and RESET on the outside of DT cases.
did you play inside. that it? do tell what you did in DETAILS.
when you power on, do all fans run, this is FIRST do they>?

I say PSU is dead, now. if fans dead.
a tech uses a voltmeter to check all PSU bus wires for proper voltages. 5v 12vdc from 5 to 10 wires. there.

curious, why ask here and not where you get faster and 10x better answers. ???
Compaq and HP changed BIOS many times, and the beeps are all different. since screen is dead i cant ask you to read what BIOS is there on said screen,its too late now. but i found your old 2005 book, seen below....

fans dead, why not report that first.??
you turn it on and the fans must stay on, for 1second
after 1 second if the PSU sees (or mobo) sees errors in power bus
it shuts its self off. all DT do that ,desktops.
then make sure the fans are not packed in LENT
the CPU shuts down in seconds if fan dies. or heat sink falls off it.

ever see this?
This safety feature prevents say blowing up a $300 processor, not yours its old $5. p4

it is a relic, a Pentium 4, ID retire it.

came with XP or Redhat Linux new. or w2000

oh my gosh, (OMG) it had a minitower version with same p/n
Ok 5100mT is minitower.
so the PSU is standard? on that I thing
show me a photo of it?
at HP forum. (in in you book seen below)
the magic trick is powering on with no memory,
powering off, push power button with power cable removed
wait 5min, put back memory sticks.

THE MT version came with windows 1000 up to VISTA
birth date early 2005, says
ohh, and to type dc5100-mt with no dash HP goes lost. wow.

the beep pages on the below is here, at HP.still after 10 years.\

page 2-21,. tells you what 5 beeps mean, amazing in the
RTM first the ask.?

does PC fail it all cables removed, not Power cable.?>
by fail mean fails to turn on run and fans blow?
and not beep.? if yes plug in VGA, see anything there
if PSU stays UP?
The PSU must stay on, does it, as must fans
this is step one, and not stated clearly.

Alienware Area-51 Desktop won't boot up long beep

The fan to the left of your RAM slots needs to spin, it may be the reason for your problem. If this is the CPU fan then you may have a dead CPU.

Contact a computer technician for repair or claim warranty support.

Take care!

HP P4SD, its running good with 4 gb RAM, P4 3.0ghz, and a couple sata hd. The problem is the fan output voltage, i havent been able to read the output chassis and cpu cooler pins voltage cause i can find...

"i can find my dmm?" did you mean CAN'T?
"its clearly off", what is off?
the fans are 3 pins,2 are power, one is RPM tachometer.
"it all works fine", so you can boot and run any OS, ?

"the voltage reads +12vdc", where, at fan or PSU?
the fans run off 12vdc, they are DC motors (from outside fan)
if the fan runs slow at 12vdc the the fan is bad or is a low RPM
fan, as some are, bigger fans run slow, for less noise.!

first is the CPU fan it must run full speed, if not the CPU will overheat in seconds and ALL CPU shut them selves (by there selves) this way. so CPU fan is first. what does it do... there....?

then BIOS screens. GOT BIOS UP? and running? with, ESC key pressed>.
let me guess your symptoms
1: PC dead. will not boot.
2: BIOS dead.
3: all fans DEAD,.
4: power switch works and all PSU voltages read right, (seems not)/?
5: if the PSU power wire reads right(DMM), matching the side sticker voltages, and the CPU is dead, the MOBO is dead, or CPU is toasted.

here is a modern PSU, sticker.
see 5 to 10 power lines, see them. all must read correctly
if a fan is dead, then its dead if 12vdc is present on the fan power pins.

NO Post test beep.- no boot screen

Could be a dead PSU, mother board or CPU to me.

First check the power source, are all connections good and switches on.

Assuming so, are there any led's lit anywhere on the tower when you turn it on or any fans turning other than the PSU fan.

If there are no fans, including the PSU, then the PSU has failed, if there are fans and led's lit then turn it off, remove power source, remove the cover and check whether the PSU is properly connected to the mother board properly (Large multi-pin plug) if it is connected properly,

After this, you need proper test equipment.

No display on computer

First thing is do you have a beep when the system boots? Sounds like you may have a BIOS issue I would start there........your RAM and processor are more than likely NOT the problem

If the CPU is dead the problems can be
  1. no power
  2. no fans etc or
  3. power, no beeps (errors)
If the Ram is not compatible it would be constant beeping.

With the board in, and power supply 20pin + 4pin Pent 4 power attached,(#2 and #7 of motherboard layout) remove power cord from power supply.
CLRCMOS0 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on
CLRCMOS0 for 5 seconds. Remove the jumper. Remove heatsink and fan from CPU. disconnect cpu and reseat it. Re-install heatsink and fan. Plug in the power cord. Try to boot up. If it still does not boot and (no power, no fans etc.) problem would then be cpu is fried.

Fans runs but no post,no beeps.

The best advice I can give you is to remove the motherboard battery (UNPLUG THE PSU BEFORE YOU WORK ON THE MOTHERBOARD) and let the system sit for about an hour. If the CMOS settings are corrupted, removing the battery will erase the corrupted data in the CMOS, which will automatically reset the CMOS to the default settings... Then, plug the battery back into the motherboard, and try to boot the system...

If that doesn't work, you should disconnect EVERYTHING attached to the PSU, and remove ALL of the add-in cards (modem, NIC, soundcard, TV tuner, whatever you have), and install ONLY the CPU, the heatsink/fan (don't forget to PLUG THE CPU FAN IN), ONE stick of RAM... you get the idea. DISCONNECT the HDD, the FDD, the optical drive, and ANYTHING ELSE from the PSU. When you're ready to test the system, you should have ONLY the CPU, the HSF, and one DIMM plugged into the motherboard. Attach the PSU connectors (both the main ATX connector AND the auxiliary 4-pin 12-volt connector) to the motherboard, and try to boot the system. If it works, SHUT DOWN and UNPLUG THE PSU; then install ONE component (the floppy drive, for example), reattach the PSU, and reboot the system. If the system POSTs, shut down, unplug, and add another device. If the system does NOT complete the POST process, the last piece of hardware you installed is probably the culprit.

Take your time with this; be methodical, and make GOOD notes about the steps you've followed, so we can help you work through this problem...

Best of luck to you; keep us "posted" on your progress...
