Yeah.. Thats the real problem.. On the test monitor, there is no picture. Although everything is on.. I think it's the harddrive jumpers, or something in BIOS that is not allowing the harddrive to be recognized..

The answer is Yes.

Connect just the EIDE harddrive from the Compaq.
Make sure the correct jumper pins on the back of the harddrive, have a jumper cap on them to set them to Single;

OR,

The IDE harddrive model you have may Not use a jumper cap on any jumper pins, for some models of harddrives, to set the harddrive as Single.

Look up the harddrive jumper settings on the internet.
Start with the model number on the label of the harddrive.

Example; WD2500JB
Western Digital 250GB harddrive that is IDE. (EIDE)

You will need a SATA optical drive now.
BIOS Setup > Boot Options > Set the first boot device to CDROM.
Install Windows disk.

Use IDE harddrive, and IDE optical drive on the same flat ribbon IDE cable?
Can be done, but usually is a HEADACHE, and MAY not work.
BIOS looks to see what drives are connected. It looks for the drive with the Operating System on it. (Windows)

Now put a disk in the optical drive. Time has to be divided between the harddrive, and the optical drive.
IF it does work; when you are using the computer, and the optical drive you will know the real meaning of Slow.

Have a SATA optical drive?

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to boot

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?

During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS the scroll down to advanced bios features press enter change your first boot device to ......,press escape then press f10 to save to cmos to restart

The BIOS is AMI. Under ADVANCED SETUP:
The options listed for 1st,2nd ,3rd Boot device include:

IDE-0 means Pri master ?
IDE-1 means Pri slave ?
IDE-2 means Sec master ?
IDE-3 means Sec slave ?

?

? single or master :::::

master with slave ::'::

???????????????? slave? :::':

note the plastic jumper is

You can remove components from the pc and try to switch it on and see if it works.

eg.I would try a different power supply.
Then try different ram,
Then disconnect the Harddrive

If when you remove a component the pc starts, it's that component thats the problem

If you try to enter in safe mode or at last known config and the laptop reboots or freezes then you need to reinstall the operating system if you want to use that hard drive on hp pavilion a1000n. The laptops have different chipset and XP requires to be the same or similar chipset to boot properly.

You have to make sure the HD is properly formated and install the XP into it... you may want to read below link which i think might be helpful to solve you problem...

good luck...

Go to Start->Control Panel -> Display, Settings Tab, and turn down the resolution of your computer.

ok, try another monitor now.

on the motherboard will be a JBAT1 terminal with the jumper across pins 1-2, so put jumper on pins 2-3, then back to pins 1-2. If not JBAT1, then it may be a 2 pin terminal called CLRCMOS, of which you put a jumper across the two pins for seconds then remove. Although, i can't think of a way to update the bios without seeing whats on the screen.

Is the Bios rom set to the on board settings for the video driver?? Did you allocate enough ram for your video driver in the Bios rom?? If all thats ok then the on board video driver is bad or not configured properly. Try disableling the On board video driver and stick a video driver card in and try and see if the monitors working correctly. Good Luck
