Peripherals not recognized

[NomadEnergy]

Computer boots up. No monitor, keyboard, or mouse.  This after interventions of a clever teen who installed "better" software that slowed everything.  Multiple re-boots by the tribe while I was away may have fried everything, but.... the computer still comes on, I just have no peripherals.  I have replaced the CMOS battery, but no change.  Any

suggestions for a plug and play type person?

[savvy2]

NO PC stated,  you did not use the full model number,   making help hard. the service tag show the full  model.

NO OS stated, we see later its w7

Computer boots up  (HOW do you know it booted to w7, if the screen is dead?)

. No monitor,  i presume this means the screen is 100% dead all the time , even the HP text "press ESC to enter SETUP" is missing

keyboard, or mouse.   if the OS is dead there is no OS mouse or keyboard actions,  only way to test them are

see if BIOS works,   the ESC key F9, F11... hot keys, power on push the hot keys, for BIOS actions. on screen.

this is first.  for sure ESC

the keyboard has lamps. LED,  many have capslock, numlock and a power lamp....  push those keys if the glow the PC has some power, and in BIOS  the keys work.

but.... the computer still comes on (what does that mean comes on , my guess fans make noise?)

, I just have no peripherals. (#1 is screen tell what you see on the screen then push ESC as the screen tells you and see if the BIOS WORKS, BIOS SCREENS MUST WORK and are FIRST. to test.

 I have replaced the CMOS battery, but no change. (oh it will ,but that will be later problems...)

 Any suggestions for a plug and play type person?  (pnp is a dream, for get pnp)

power on tell what the screen does., ALL THINGS.

text?

hP logo from BIOS

windows 7 login screens.

then push ESC key is the screen tells you power on,  if the message is missing now, tell that now.

> Computer boots up. No monitor, keyboard, or mouse. 

With the computer powered-on, press the button to open the CD/DVD drive tray.

If that component is receiving electrical power from the power-supply, it should open.

Can you hear the computer's internal fan making any noise?

Any warm air coming out of any exhaust grill on the computer?

Any lit-up lamps on the front-panel of the desktop (or anywhere near the keyboard on a laptop?

Turn the computer off.

For a "desktop" computer, make sure that the monitor is powered-on, and is connected to the VGA-output port on the back of the computer.  (For a laptop computer, the internal screen is probably working fine.)

Turn the computer on.

Do you immediately see anything at all on the screen?  A "logo"? Any "hints" on the bottom 1 or 2 lines on the screen, such as "press ESC to ...." ?  

Any white-text over a black background, enumerating the components (RAM size, CPU speed, detected disk-drive) ?

Does it start to boot into Windows, and show a "crawling worm" or a "spinner" animation?

How "far" does it get in the boot-up process?

Thank you for your help!

I have embedded in bold my replies to the questions you have asked...

> Computer boots up. No monitor, keyboard, or mouse.

It does open.

 Can you hear the computer's internal fan making any noise?

I can hear the internal fan humming.

 Any warm air coming out of any exhaust grill on the computer?

There is warm air coming out of the exhaust grill.

 Any lit-up lamps on the front-panel of the desktop (or anywhere near the keyboard on a laptop?

All of the lamps on the front panel are lit.

But…. The monitor Is on because it is plugged into a wall outlet, not the computer.  It is not receiving input from the computer.  The keyboard does not “light up” (no all-caps, no number lock).  The mouse does not light up either.  

Turn the computer off.

The screen does not react to the computer being turned on.

 Any white-text over a black background, enumerating the components (RAM size, CPU speed, detected disk-drive) ?

There is no input from the computer.

 Does it start to boot into Windows, and show a "crawling worm" or a "spinner" animation?

There is no apparent boot process visible on the screen.

 How "far" does it get in the boot-up process?

It does not get anywhere in the boot-up process, at least that is visible on the screen.

Thank you for your help!

I have embedded my replies to your comments in bold.  Still plugging away at a solution, but I fear the mother board may be RIP.

It came with windows 10...?

It did not come with windows 10…   

Plug and Play is dream , only seen in SCI FI,  see the movie, "PASSENGER"  (PnP hell is correct title, and love it)

Plug and play was just an expression to demonstrate my low level of sophistication regarding what’s inside the box.

no PC is kid safe, indeed! And nor is the furniture.

we use to run  virtual box with windowns, and then when turned off and back on , all that was there before is gone,just   clean load of windows, 

we kept them out of the real windows.(base)

im at your h9-1300  was w7- W8 new.

the 1400 was 7 or 8 windows

so you upgraded, and that matters/.

so you did the upgrade  but how, HP didnt do that?

if your PC was not upgrade the F11 key would putback W7 or W8 as it came day 1 from HP say back in 2015 (first ones)

but that will not work now. after doing a non HP update.

lets not guess?

you power on and the fans run? ,the PC then has  working keyboard and you hit.  the ESC key rap rap rap

Power up and fans fun.  PC does not have a working keyboard…. So no bios.  Screen is not dead (plugged into AC directly, just not receiving data from computer)

at power on switch , just after that.

BIOS comes up on the screen, IT MUST or the PC is dead, PSU dead or the screen is dead.

the SCREEN has  button called SELECT, press it see the screens own OSD menu, good, its not dead.

if no OSD the screen is dead or not plugged in,  AC line power.

The menu option works, and the screen is still alive.

once the screen tests good we  do the ESC key test.

The keyboard is not communicating with the computer, so no ESC key. 

ever seen BIOS>??

Seen Bios before, but not since the latest adventure began..

here is a BIOS screen ,

ESC then press F1. on this PC

btw, this  works even if the HDD /SDD disk is missing, or unplugged.

this is a Laptop but BIOS works just the same way.

http://pcdied.com/top-coveroff.JPG

 I will go look.  Tx.

[savvy2]

so the External unstated monitor seems ok, its own MENUS work   press the monitors select button on the front

and the monitgor (unstated make and model) comes on a OSD screen.

if that works the monitor is probably ok..  (I was joking about PnP it is a great target for jokes, for sure)

The monitor is on.

then turn on pc,  and the monitor may shows, lost signal , or lost sync, or sleep mode warning

but if the PCs video card is 100% dead on all 5 key wires in the VGA cable, it many not show a warning.

but some do, its the  makers decision, if this monitor is older that 2002, it well be a pain,,,, no montor told by you.

Seems your PCs VGA card is dead. (or PSU dead)

The PC that gets full power,  5-12 DC power rails all good the PC then boots to BIOS first., ALL DO.

when that happens messages are sent to the VGA card (or chip) out to the VGA port to your External monitor

you can remove the mouse and key board and nothing ever stops,

'hit ESC key to enter HP setup"  this text message shows everytime you turn it on. for all times you did in the past

most folks never even notice this,  and is KEY TO DIAGNOSING ALL PC's made.

so forget all other comments, and things, like keyboard is dead.

the BIOS is dead.

that means the PC is dead, no power to the key chips,  needed to make BIOS dead

or THE VGA card is dead, (some PC have 2 VGA chip)  i cant see inside your PC

one is on board,

2nd is on a CARD.

if you pull the coin CELL, willynilly , it can switch to the other VGA jack, and now VGA is DEAD.

so look on the back of your PC , does it have 2  VGA jacks or DVI?

I cant see what is there, so must ask..

The sounds you hear are mostly just 12vdc, working and running fans, and not proof of much .

so if there 2 VGA jacks there try them both now. power on and see what you see on the Screen.

IF BIOS is dead, it can be many things but , ill just do modeles.

the DVD eject button is  great idea from poster. if works we know that 2 power feeds are good, 5v and 12.

1. Bad PSU
2. a module is shorted, killing power rails.?  work that idea.
3. 1 of 2 or 4 RAM (DMM) sticks is bad try running each 1 by 1. (dead cold power, ask how)
4. bad CPU ,say the fan is dead, or the Heat sink fell of or is loose.it overheats in seconds can.
5. bad VGA card if one slot has this card, look for 2nd VGA port to test.
6. bad VGA cable. (unlikely but happen)
7. unplug all SATA cables to all drives and all USB devices now.  that means ALL HDD and DVD drives.
8. bad MOBO. (or its vga chip blew up on board)

level if possible the monitor connected,  to all VGA ports is possible to see messages of ANY KIND>

to pull ram, or unplug the PC form the WALL POWER, push power button, it acts odd, for 1second, , then wait for 30seconds or more

and then pull ram,  this protects the RAM from dangersous hot switching.

keep on

one hand , the other touching case metal. this kills dead ESD events......... we use a ground strap on the wrist

sorry NO PnP here, its  dream that....

The PNP way is

try monitor spare , known good.

the replace,  the whole PC case and all. 

that is the only PnP there is.

[savvy2]

the post could have started as

my desktop BIOS dead, it never signs on to the screen, ever. the screen is DEAD, at all times, (except self tests of monitor OSD)

and we work that.   (its a  serious hard fail of the system this)

what Monitor do you have. name /model

sorry for 20 questions but really we can not see what you own. at all.

and what your full MODEL Number is. seen at the RED arrow below, this helps GREATLY !!!

[savvy2]

here is what the monitors does when BIOS is alive , even with HDD missing, DVD drive missing, all usb devices missing.

you never posted the external monitors makers name nor model.

Some folks here post like this and have this old CRT monitor, from 1990 conected to a 2010 PC

and the monitor must be warmed up to see messages at all. or you miss them.

the below is  LCD, and its puts up message instantly (near)

tell me you dont have photo below of Miss Piggy... #1., photo 2 is LCD

[savvy2]

here is one more tests

chips  can latch up, or the BIOS can do odd things,

so we unplug the PC from the wall

then push power button, on mine the fans run for 1 second and die (this discharges the PSU  100% or near)

then let it sit for 1min or even,  1hour.

the put it back inservice,  again to see if BIOS WAKES UP>  it must or the PC is DEAD.

> All of the lamps on the front panel are lit.

It is a bad sign that ALL of the lamps are on, and are staying on.

I would have expected that powering-on the computer would momentarily illuminate the lights, and then the lamps would extinguish, as part of the POST (Power On Self Test) self-diagnostic procedure.

> The keyboard does not “light up” (no all-caps, no number lock).  The mouse does not light up either.  

This is another bad sign. 

If the POST successfully had completed, the motherboard would have sent power through the USB ports to light-up the lamps on both devices. 

So, I am thinking that the motherboard has failed.  Sigh.  Don't shoot the messenger! 

Lesser possibilities:

* bad CPU

* bad power-supply (it should be emitting several different voltages on various leads; if one level is "missing", compare to driving an automobile with one flat tire)

* bad RAM

There's not much you can do.  A qualified technician might be able to find a replacement motherboard (expensive!) that will be compatible with your RAM & CPU.  Of course, the disk-drive still contains your personal files, and the CD/DVD drive can be "cannibalized" and re-used.
