Question about HP Pavilion Computers & Internet

3 Answers

HP9515Y - when attempting to boot, the fan starts, then stops. There are no beeps as in a usual bootup. The monitor does not find input.

Sometimes (but not always) unplugging both the monitor and PC (and removing everything except the monitor keyboard & mouse) enables me to boot the machine. I have run every video, component, memory, motherboard and system diagnostic provided by HP and find no errors at all.. I've checked every cord and they all seem ok. I would really appreciate any suggestions on next steps to try.

I had the same issue 3 years ago. It was a very simple fix ($10). The thermal paste on the processor had turned to dust. PC would begin start up, go "I'm overheating!", and shut down. This would then start the loop of it starting, stopping, starting stopping. Found out when I removed the heatsink, and then placed it back on and it worked! Buy new paste, put it back together and you can save you PC (it's still going 3 years later now).

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)

ever clean the best out? every year.
as seen here,

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

    also the smarter and better the PSU
    the more easy it can shut down.
    over voltage, under V, and over current.!

    this is so a bad PSU cant blow up $300 8 core CPU. or more. a $300 GPU card.
    the PCU can fail and blow up $1000 PC> easy
    so we use the most smart PSU, we can get.
    see? (ask how or see page above for choices)

    hp/psu. #5188-2859, in fact.
    vastly better PSU's can be fitted.
    even with huge silent fans.

It is an Hp. If it has AMD graphics, I would suspect and AMD chip and fit a new one.

    here is what it had new.
    and has its own fan, and if packed full of lent
    clean the PC first. or all this bad happens.

    I bet there are 3 fans to stall full of lent
    just like mine does every year.

    clean it first, and amazing things can happen.

    my custom DESKTOP
    it shuts down for many BIOS reasons.(programmable)
    3 things overheated
    Fan RPM below my settings,
    and all processors in mine can shut it down
    my GPU too (or the HD power lead fell off)
    the PSU on mine can shut down for 8 reasons
    all PCs can shut down for
    over voltage
    over current
    under voltage (most)
    over heated (many things, on top brand PC)
    all processors self shut down for heat.
    first they go slower, and if the heat is damaging the processor HALTS (ask intel and amd for details)all do that.
    if you ship a desktop from point A to B
    the CPU heat sinks can fall off, and bam, overheats instantly and shuts down.

SOURCE: Computer Does not Boot correctly, Monitor is Black.

Hmm it seems to be problem with Power Supply, but still if you can give a try connecting your system into other socket may be which is properly grounded one.
if the above didn't fix your issue, i would suggest you to disassemble and then assemble it again. try changing the data cable as well..  Last option left is if you have a spare SMTP checkout with that.
Let me know if it works..!!

SOURCE: PC will not power up. No fans, lights, anything.

Have you tried a different power cord? (longshot, I know, but it is one of the variables that you don't mention)

Have you tried a different A/C outlet?

Computer will start up but screen will stay blank

do you get a 'NO Signal' display on monitor, or anything when booting?
if not check to see if you can see lights on inside the frame? if not, do you hear fan spinning or beeping? sometimes the fan on the heat sink over the processor will stop spinning. the chip needs cooling so if fan won't spin an error will not let pc boot up to save it from getting too hot.
if you can take frame off and find the processor chip on motherboard to see if it is spinning. if not that would stop it from booting. if it is spinning then it is something else like the graphics card failure.

My dell latitude c510/c610 failing

Sounds like the fan may be failing and need replacement. On a system that age, it is debatable whether it is worth fixing.
You can boot to he resource cd and run fan diags is you want to try and confirm

Fans can be found on EBay

When pluged into outlet fans spins and doesnt stop, wont boot

Fan spinning hard is usually a CPU issue.
If you've made any hardware changes to your computer, undo them. This happened to me when I was trying to upgrade my Processor (CPU) and I had the wrong kind.

PC bootup problem

Double check your connections ( the cord between monitor and computer{usually has blue ends}, they always wiggle lose) . If that doesnt fix it, buy a new cord and check for video card updates.

Gateway 675 fan problem

Check the BIOS in the laptop. The CPU fan and unit fan is controlled by temp. U can set it for a lower temp. The Bios is accessed when U boot up... F2 usually, There should be a 5 to 15 second screen telling u what to press to get there.

Good luck

Constant beeping

I would first check that all the fans are turning when you first power it up. It may have fan speed sensors on them, and one or more fans aren't coming up to speed. I would check the CPU fan(s), as they are usually smaller, and tend to go bad before the other larger ones.

Fan error during boot-up

Power supply, that can be the cause. Did you try disconnecting few devices to check if the CPU fan has enough power to turn itself on. Usually motherboard will have two connectors for the CPU fan, you may try connecting it directly to the power supply. Also Check through the BIOS and see if there is a setting to disable the CPU Fan monitor (Hardware Monitor??) It should be where the temps and voltages are. The BIOS in most computers has an option to monitor a CPU fan. If none exists, then the option needs to be disabled. I am assuming the error is occuring during the BIOS stage of bootup. If the error occurs in Windows, it may be that some software has been installed to monitor a fan that doesn't exist. Sometimes monitoring software comes on the motherboard CD and someone may install it, thinking it is a driver. It is not necessary. Good luck!
