Video stopped working... pc starts to boot ok, then monitor shuts off as there is no signal to it. This is a refurb pc that I've had for only 6 months. How do I know if its the board or the video card?

what fan there are 3!
ok, first things first.
an old desktop.
HP Pavilion Elite m9515y no monitor stated,
did you fist test the monitor to be sure its OK, on any other PC
simple tests, like this help, for sure both bad......!
did you know a 2002 monitor has and internal sleep timer clock that can be very confusing, no monitor stated make or model.

at least.
it is dead pc for sure. fan dead = dead PC.

let me say it sounds to me like the PSU is dead.
right off.
but I do tests first.
is the fan on the CPU running full RPM with power on?
if not pOWER IS NO GOOD, or the fan is no good
the fan must spin or the PSU is bad
OR !
or the PSU found shorted parts up stream.(power bus)
all PSU can shut off in 1second less.,
we strip the system down to make sure there are no shorted
devices there.

unplug , all HDD, SSD and DVD/ CD drives
all PCI cards out
does the power stay one now, and CPU fan turns. fast
or is it all packed up in lent. as all do.

PSU dead , 1,2,3'4,5,6.... (we use voltmeter)

that PC will overheat. easy
fans stall.
vents blocked
all that. bad bad bad.to the bone.
the CPU will shut down overheated, all due
(intel inside or AMD) both do . self preservation mode.

No signal just means the video card isn't putting out any signal. If you don't even see BIOS then replace the power supply first. Still doesn't work then it's probably the motherboard.

So either the computer isn't generating a video signal, the cable isn't carrying the signal to the monitor, or else the monitor isn't capable of receiving a video signal.To test this, first try a video cable that you know is good, in case your cable is bad, If it works with the other cable, the problem was your original video cable. If it still doesn't work, put your original cable back, and hook another computer up to the monitor. If the monitor makes the same message, the problem is with the monitor. If the other computer works when connected to this monitor, your problem was that the original computer isn't booting (which could be due to several reasons I will list below), or the video adapter is broken.Possible reasons for the computer not booting: bad power supply, bad power button, bad hard drive, bad memory, bad motherboard component. If you determine that it isn't booting, unplug everything except the keyboard mouse monitor and power cord, to see if that makes a difference. If it boots after that, something you unplugged was causing the problem, plug them each back in one by one, rebooting in between, and when it stops booting properly, the last thing you plugged in is causing the problem.

Hold down Function button and click F8 key to tell the laptop to send signal to the monitor.

I'm assuming after a few minutes, it does get a signal from your computer and all works? It does take about 30s +/- 90s for a computer to generate an output video signal so if your monitor comes on first, before the computer can send a video signal, then you'll see that message. You should see the same message if you shut down your PC and leave the monitor on.

boot your pc , keep on pressing f8 key then select safe mode option, remove the graphic driver, then shut it down, then again start install the graphic driver

the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

Connect another monitor to your PC. Set the screen resolution to a lower value and click OK. Shut down the PC. Connect 786 to your PC and boot the PC. Does that solve your problem?

I have been having the same problem with my hpvs17 monitor when i start to use my web browser on linux distros. Now, for the next few days i am going to try my system on a regular crt monitor. if the monitor does not crash, than i will have to say that the hpvs17 monitor has a defect.It seems that when i go online, while i am in the middle of searching something, the monitor just shuts off and i get "input signal out of range".

It is the same problem I experienced and now it suddenly stopped and dead.

what the manufacturer of the unit has to say about inherent design fault which they are liable under UK consumer law to rectify within 6 years

And incidently who are manufacturer to this Licon make is please
