Mother board or HD issue?
Started having problems with the pc hd recovering from sleep. Progressively got worse to the point that once the pc was turned off it would not power back on. When I got video the other day I turned off the HD sleeping in control panel, ran defrag, and scheduled check disk. Check disk ran fixed a couple of errors then rebooted. No video. Next morning, turned on the computer again, had video so I went into the bios to check the date of the bios. On a different computer I downloaded some drive firmware updates and a bios update. Restarted the computer and no video. Haven't been able to get video in 2 days.
Symptoms
When the power on button is pressed it flashes amber briefly then stays solid blue:
1. Green CD light turns on and flashes. The tray opens and if you put a CD in it, the light flickers as it reads the CD.
2. The amber HD light turns on then stays off indicating no activity.
3. The keyboard lights (num, caps, scroll) flash once, then nothing. If you press num, caps or scroll lock, none of the lights come on (any keyboard).
4. There is no video - no connection (any monitor).
5. If you plug in a network patch cable, the network lights flash normally as connecting to the network.
6. The fan is on and working.
7. The power supply indicator light is a solid green indicating the power supply is working correctly.
8. When I flip flopped power and sata cables between the HD and the CD nothing changes in the power up sequence above.
9. When I disconnected the HD cables (sata and power) completely so only the CD was functional and inserted a PC Doctor for DOS bootable CD and restarted the computer conditions 1-9 remained the same, except there was no amber HD light.
10. When I only had the HD connected, 1-9 remained the same, except I had no green cd light, only the amber HD light flash once.
Any ideas or suggestions?

I called HP support this morning and they are going to replace the motherboard. They are even picking up the shipping cost. No discussion and no hassle. Thanks for your help and encouragement... and Bill thanks for all the things you tried that convinced me it was time to call support.
This mb is junk. HP has replaced mine 3 times and it seems it needs to be replaced again. First time the mb quit recognizing the PCI-E slot, the second time it would not boot at all, the third time again the PCI-e slot quit working and now the forth time it plays peek-a-boo with the video card, sometimes it's there and some times it's not. This system is the hottest running system I've ever owned.
