When I started the computer the monitor wouldn't show anything. The lights come on and the fan runs on the hard drive, but nothing showing on the monitor. I tried to hook the hard drive up to my big screen to see if it might be the monitor. The initial start up was visible, Compaq, Windows XP message and than it went blank and the screen read signal? I'm not sure if this is an issue with the monitor or the hard drive. Please Help!
ITTech06 THANK YOU SO MUCH... Had the same issue than luv2luvme78. Tried your solution and it worked... U're awesome... Many Thanx. Thought I'll have to trash my pc which has bunch of info I still needed.
Unplug power cable from of the PC. Then hold power button in for 30 seconds, this will drain the capacitors, then plug back in the power cable see if this helps, if not could power supply, or video card.

1) Is this a laptop or a desktop?
2) What OS are you running?
3) When was the last time that it booted successfully? Did anything change then? Did you upgrade the OS? Did you upgrade the software (firmware) on the processor (Intel or AMD)?
4) Do you see anything on the screen? Compaq logo? Boot options?
Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.
If this is helpful, please comment and rate. Have any other questions, please let me know.
Could be the monitor or your Presario's VGA card. Swap the monitor with another system to see where the problem lies. If another monitor works on your system , it's your monitor. If another monitor doesn't work, then the problem is the VGA card.
Unless the power button sticks or does not pop back out, i doubt the issue is in the switch, but it can be tested by replacing it with a momentary switch from Radio Shack (not an exact fit, but good for testing)
This sounds like a power supply issue. That would be the first thing to check. If it is NOT connected to anything except the power cord , it shouldn't run unless switched on.
Could also be the motherboard, but before you start dismantling the computer , check the obvious. Open the case (usually to screws on the back) inspect all the cables, reseat your ram chips and addin cards.
Not to scare you ar anything, some of these presarios have bad capacitors on the mother board. coupled with the fact that they are difficult to clean (inside) and airflow is not maximized in the case, they tend to cause the capacitors to swell and leak, losing voltage.
When you are inspecting the insides of your case, take note of any capacitors (little cans with crosses on the top) on the main board inside around the CPU fan that are swollen or leaking.
If you find these in bad condition , i would replace the motherboard.
Firstly the keyboard does blink, but do you hear 2 beeps one then another a few seconds later, if not memory or graphics fault.
Are you able to start in safe mode(press F8 when pc is booting up)when menu comes up highlight 'Start windows with last known good configuration' then press enter and it should re boot.
The graphics card(if it's not onboard)may need to be removed and re seated, also the memory.
Also check hard disk drive ide and power cable.
