Hp P6000 fans stop after 15 seconds. Hard drive light stays on. nothing on monitor


dead PC, DESKTOP PC ,as old as 2009.
the fans tells you the PSU shut off, for cause.
fans, so you saw all fans turn off or just 1. or 2 of 3.
my pc has 4 fans many have 3;
CPU fan stops ,cpu overheats , PC goes slow or dead. clean the lint off it.
GPU fan , video goes dead. if it overheats.
PSU fan is inside the PSU if it goes bad, PSU is bad.
no monitor stated, is it CRT or LCD is it 15 years old.
if the monitor is 2002 or newer the OSD screen works
even with PC turned off, press the select button see that OSD screen ? telling you the monitor is not dead in 1second flat;
i caN NOT understand why the HDD lamp glows,
if the PSU shuts off , most LEDs go dead, on my PC
the standby LED on the MOBO glows, unless you pull the PSU power cord.
your HP PC came with 9 different mobo, during its production run.
at least. so answers come harder from that reason.

here are some simple tests.
test 1
power on, hear fans run
does the DVD drive (or cd) button eject work,.?
do all fans not just 1 or 2 worK? look for all fans clean the lent out
or things will overheat,
PSU can be bench tested or in the PC case.
using a jumper wire, even the HP service manual covers that.

power on the PC (after keeping monitor on for 5 full minutes)
test 2
the Screen must say, "hit ESC key to enter HP setup" BIOS.
press the ESC key on the monitor
if no text shows up that is a dead PC< "text above missing{"
if the PC told you to hit another key do so.
The ESC key , activates the BIOS brain. this cause
all those pages to work as seen in your service manual;.
if BIOS is dead that is a bad PSU (monitor ok)
or CPU is overheated.
bad ram, take all sticks out and test 1 by 1, ask how. !
The PSU will shut down on up to 12 or more faults
but never shuts down the standby power bus. unless AC line pulled.
IF the PSU has fan as most do this is the first place I look.

Hannstar ACER j mv-4 doesn't start up


no pc stated, maker or model #,, sounds kinda DESKTOP>?????
no oS stated
step one is test the MV4 on a known working pc,!!!
why wait, this so basic....
are you using VGA to VGA or DVI to DVI connections??????

the DESKTOP,
no sound means the fans are dead and PSU dead.
The PSU will run for 1 second and fans run now. if not PSU is dead.
if fans do run and stop that means PSU dead or mobo shorts or bad reg on MOBO. or bad ram. strip it down to test that.

ok fan runs that means 12vdc good. if stay running,
and if PSU stays up, then NEXT TEST IS Screen
is it 100 % dead, or do you get text or logos."
100% dead means to me bad VGA card(or chip GPU)
if the Hot key for BIOS fails, that means bad POWER/
or bad VIDEO card.

the fans run but are silent, I envy you.. sell me your fans....
im 1/2 deaf from Vietnam and can still hear all my fans.

my DT has 4 fans min. (it's Alien-ware box++++)
CPU, GPU and PSU, and 1 case fan,all must work.
do yours?

when you power on a PSU, the fans run and stay running
if that takes sides off so be it, ever clean the 5lbs of lent seen inside from 5 years, collected?
If you dont service any pc, this packs up and the CPU overheats
and shuts its self down by DESIGN.
why no do that service first.
see that CPU, see those fins, see that pack up there.
blow it out, outdoors, using CAN-0-AIR

mine over heats my GPU fast with lent, my Graphics car runs super hot and fast and lent is NOT ALLOWED here. ever..

old pcs with slow cpu ,, tend to packup slower, well lets say
they can run longer with huge lent here. its just slug processor so...
that is what it does.

recap.
  1. fans all run.
  2. BIOS dead?
  3. screen dead. no words no text at all.
  4. MV4 tested on other PC works. proves PC bad.
  5. LENT PACK job. as all do every year here, all.
  6. Bad VGA caRD. or using wrong port if PC has 2 VGA jacks. !

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.

I have a Compaq Presario SR1830NX desktop, I leave it on all the time, when I got up this morning, it was off, so I pressed the power button, but it doesn't power on, nothing happens.. I checked the power...


step 2 the TECH uses a voltmeter and checks all wires on PSU for correct voltage.

PSU in Desktop dead, my guess fans dead too right>
you never said, what it does inside PC ,except nothing
does nothing mean dead silence?
the fan must run for 1second, then goes off.
a 1 second run tells me the PC power switch told the MOBO to turn on and in turn it tells the PSU to turn on,
the PSU then turns on for at least 1second,and if the voltages are ok
then the PSU stays on, else off goes.

15 and 16?
the 20 pin older supplies those are both ground
but 24 pin ATX pins are correct there.
the voltages are here.
https://en.wikipedia.org/wiki/ATX


There are 2 causes, of dead power button.
1: the buttons 2 wire cable ends fell off. at button or PC mobo.
2: The PSU is bad.
3: the MOBO is bad.

The mobo can also shut off any PSU, if the PSU fails
or it sees the regulators in the MOBO fail.
the Desktop runs on many power rails.
some in the PSU, others on the MOBO.
THe mobo creates special low voltage for the CPU.

the power good pin, does that #8,
One way to see if the MOBO is overload
is to remove things from it, I start at RAM
lacking a voltmeter, this is very hard to fix any thing electric.
only guessing or pulling objects PC can find shorts.
pull all power cables there, hdd, power, cdrom.
all things that use red/yellow wires.
all SATA cables, all USB , then ram. even a fan can short
a good tech keeps an open mind, and finds why the PSU shut down.
in most cases, the PSU is bad. but not always.

This is a feature, of ATX it keeps you from blowing up say a
$300 microprocessor.... or fancy gaming Video card (have one)?
yes, pull the video card too.

What does flashing light mean on a Bestec atx-250-12Z I installed new ram and now computer will not turn on - no fan, no beeps, just dead. I have now removed the new ram and returned to original ram but...


no PC stated, must we guess all that?

there are 2 causes,, (3?) fans dead, even inside PSU?????
1: bad PSU
2: the motherboard or all modules connected can short and bingo.
3: power switch cable fell off?


a desk top has 2 to 3 fans or more.
PSU
CPU
GPU
case.

at least the first 2 are there and MUST SPIN
if not 12vdc is DEAD.

Dead psu


Apply a new PSU, the question is is it worth it to you? A psu is rather expensive to replace I would not try repairing it if I were you.

Goto copytechnet.com.  That site is like fixya but it's copier technicians only solving problems.  They should be able to help you with the PSU diagrams.

Fans won't start on my compaq evo


I suggest replacing the fans with new fans. Fans do expire and they need to be replaced.
