Dead processor. good hard drive

Sounds like it might be a motherboard issue BUT the best thing to do is to put a known good working hard drive in that computer and try installing Windows from the cd. If it can't install then the motherboard is bad more then likely. You can also try swapping out memory and trying it in different slots as well. If somebody tried flashing the BIOS and the computer got shut off by accident, that can screw up a BIOS and render the computer useless.

Assuming there's no fuse in the mains plug or that you also checked it and its good, it sounds like the Power Supply Unit (PSU) in your pc tower has failed.

They're fairly easy to change, and if you're not too proud, fairly cheap second hand or from ebay.

The you'll need to disconnect everything, take the cover off you pc tower, the PSU is usually at the tom and back of the tower, the mains cable goes into the back of it.

Taking it out it fairly easy, there's usually just four screws which bolt to the back wall of the tower.

Then there's loads of connectors, Motherboard, possible ancillary to motherboard, one to each hard drive, one to each disk drive and one to the floppy drive.

All the connectors are key coded (Special shape and size) so you can't put them on the wrong device.

You'll need to get hold of a replacement, either the same power (no. of Watts - 250w, 350w) or better.

Putting the new one in is the reverse of taking the old one out.

Its straight forward, but give youself plenty of time and space to work in.

Oh ........ and give it a good dust out while the tower is open, helps stop the CPU overheating.

The easiest way to backup your system is to go to your local computer/electronics store and pickup an external hard drive. If you don't plan to back up a ton of info, then you could use a large flash drive and manually copy the files over. Most external hard drives will come with backup software. If it were me, I would just disconnect the hard drive before I installed the processor. Once installed, power on the computer with the hardrive disconnected. If the computer is able to load the BIOS and displays something like "Boot device not detected" or something to that effect, then your probably good, because if you did it wrong or the processor was bad, then the computer wouldn't turn on at all.

Simple. Remove the drive and install it in a similarly equipped computer as a slave drive. What I mean by this is your drive is either a IDE drive (wide gray data cable) or a serial SATA drive (no wide gray cable) - the receiving computer would have to be of the same type to accept the drive

Before you do this ... who told you the processor was dead? It may be worth taking to the Big Box Store for a Free (as advertised) computer check up.

Your A50 doesnt lent itself to upgradability - I dont think I would put much into it to repair. However, you may be able to find a used replacement processor for a reasonable price.

yea you got a bargain

pavilion a605 what is the full service tag data????????
age shows as 2000 to 2004 made, wow 18 years old possible.!!!
so the un named monitor and model number , is dead.
(a good monitor sure but is dead blank all the time)
so does the MONITOR show:

• no sync?
• no signal?
• out of range.?
• power saver mode going active?

Those are all top clues from any monitor 2000 to now. all do that.
can.... and is key facts.

then you boot the PC and there must text seen now....
for 18 years, now, " hit F10 to enter setup) HP BIOS.
No text, but say , monitor pops NO SIGnal?
that means the video chip is offline, or the PSU is did or
up to 10 other things dead on or attached to the motherboard.

all else inside any pc made must be good !, or the video chip will be off line ! see?
the computer inside must compute or he video chip will be asleep (off line not bad most times it's not bad the GPU chiP.


we cant see in side your PC, at all here, and matters !
are there 2 VGA jacks there, 1VGA and 1 DVI? I cant see it.
as all desktops, even SFF you can add cards to it, and did new.
options, its called new. and for 18 years added to it.

the PC must turn on, does it and stay on?
do all the PC fans spin, all must, PSU fan and CPU fan
and if GPU has fan?, it too must spin and blow air and not be packed in lint. and then overheats and shuts off fast.

This pc had many options back in year 2000.
even TV cards.(and vast more, called PCI cards old)
It does have a (vga jack on mobo)
Intel® Extreme Graphics Integrated w/845G Chipset
it has the integrated onboard GPU chip above.

first PC power must be good. PSU fan must blow? does it:?
PSU is that thing the power cord inserts.
CD eject button works does it?
the coin cell RTC battery must not be dead. as all are this 18 years OLD!
fans heard and seen to work and felt to blow air.
heat sinks not packed.
then the VGA jack will show data , RAM not bad, no shorted HDD or shorted, CD drive.
no shorted floppy drive, it has one this old
That is about it for bad that can make any pc fail.

see black screens here
most PSU replaced say 10 years ago, have 1/0 switch on the rear,
all mine do, all are top end PSU,s here and if kids turn it off to "0"
there will be no power until you flip it to 1.

You can buy an external USB drive enclosure, mount the drive in the enclosure, then connect the old drive to the new system.

here is a popular model:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817729001

if teh old system is a portable, then there are 2.5 versions also available

If the hard drive is is not damage maybe you can save all important files on it.

Please do the step by step troubleshooting of your laptop.
REmove the following:

1. Memory
2. hard drive
3. processor:
4. Battery

try this;
1. Fix some other connection inside the laptop
2. Insert AC plug then start the system.
3. shutdown the system
4. Insert the processor
5. swittch on the laptop.
If beeping; continue
step 3;
6 insert the memory.
7. start the system
8. If display, connect the harddrive.

in step 5: if not beeping:

Either board or processor is dead.


IN step 8.
9. start the system.
10. if the hard drive is detected, and cannot continue booting
i recommend you to reinstall the windows.

Please notify me if problems arises. i will give you further instruction, melnavz.

Check the monitor plug that goes to the computer for bent pins. or try another monitor/or cable .

Does the laptop post at all? Does anything come on the screen? Might not be a dead hard drive. If it was you would still get into the bios etc.

IF it is the hard drive (unlikely) then u can buy an adapter to plug it into a desktop and if your lucky u may be able to recover data using something like active file recovery.

Have you tried plugging it into a monitor to see if its the screen thats failed?
