Windows 7: system boot failure on HP Pavilion P6000 series

system boot failure on HP Pavilion P6000 series

problem started within the last two weeks. PC just started boosting fan noise and then just blacked out. now each time i turned it on, it will give me 2 options prior loading system: 1) start-up repair - recommended, and 2) start windows normally. i've tried both but it just blacked out every time after a few seconds so i never got to the welcome screen.

i already tried these:1. replacing hard disk with one from broken PC and same problem as above. 2) corrected modem fan because it got fixed the wrong way by someone when they replaced the burned power supply. 3) re-seated the 2 ram sticks. 4) hooking hdd cable onto another slot on the motherboard.

maybe it is also important to note that pressing power button turns on the computer but the power-on light never even blinks or stay on except the hdd light which eventually goes out after a moment.

please help.

regards and God Bless,

If I was a betting man, I'd say you have a faulty power supply.

I realise you've already had one replaced, but I still think you should get it checked out and work from there.

i'd say you are right because the power supply is not totally closed, you can see its inside from the back of the PC. but what about short (electrical) power source? i always unplug all cables from power source prior touching the PC to try something because the back casing is electrified.

if the power supply has to be tested for faultiness, does it mean i should take it out and give it any electrician to test it with a test meter or something?

appreciate anything and everything.

God Bless,

If you don't have any test equipment yourself, such as a multimeter to measure the output voltage, any competent electrician should be able to do the checks for you.

It shouldn't be necessary to remove the power supply first, but if you decide to, do make sure that your computer is disconnected from any power source first.

i've just replaced the power supply with a fine one but same problem persist. i also tried plugging the cables to a different power board to no avail. the excessive fan noise comes from the cpu fan.

if you still believe it to be a faulty power supply then maybe i now got two of them to be tested. i would also appreciate ideas of what might have caused this problem in the first place.

please help still. God Bless,

It's highly unlikely that both power supplies are faulty.

In this case then, you probably need to consider that you may need a new motherboard and CPU.

Do you feel confident enough to do this yourself? If not, it's best to get the job done by your local repair shop.

However, in view of your location (Gilbert Islands?) you may have to send your computer away for repair.

Thank you for the advice. Can you please let me know what might have caused this in this the first place so I prevent it from happening again to future PCs? I will give this PC to ITs at Ministry of Line & Phoenix Islands Development (MLPID) for them to try fixing it, but if they are not able to, then I will import a new motherboard and cpu of the exact make and model.

Thank you again so much for your assistance and God Bless,

Reading back through the thread it's quite likely the original failed power supply damaged the motherboard.

Can you prevent it from happening again? Highly unlikely, as hardware can and does fail at any time.

Your best protection against data loss as a result of such failures is regular backups to an external hard drive.
