Most likeley a motherboard failure. I have alot of HPs at work that do this. The connector for the hard drive on the mother board fails and it will do this.

If thers any kind of warranty, I would contact the manufactuirer first.

Asuming though that it isnt, then I would say, try to find a spare parts one online for cheap that has a good MOBO and change it out.

If you remove the Hard drive and try booting wihtout the Hard drive in, do you get the BIOS or SPLASH SCREEN?

Also, try removing any other add in devices to be sure that they arent causing any issues. I.E. the CD DRIVE, ANY PCI CARDS ETC.


If it starts with just the power adapter but no battery. then its definatley a bad mobo.

Let me know how it goes.

Start wont load window, just flahing light on screen. may have got virus

Remove hard drive, find out make and model of hard drive. Go to hard drive manufacturer's website and download testing software (if you have another computer with internet access). Should be a bootable ISO file. Burn the boot cd and run it on the host computer after reinstalling the hard drive. Sounds like a bad hard drive in my opinion.

Monitor displays breifly then goes to blank screen

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Black screen not booting

check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.

Did you recently change or install a program that would affect the resolution and card output? Try booting into safe mode by holding the "shift" key during boot. From there right-click on the desktop and hit 'properties'-> 'display properties' -> 'settings' , check your resolution and drop it to 800x600 and then reboot. If everything goes back in normally make sure you have the right windows drivers for your video card. You can also check the driver version and settings while you're in safe mode. Sometimes the windows update drivers can act screwy and I would recommend getting them directly from your card manufacturer.
