GREEN LED LIT ON P4B266-LA (Danube) SYSTEM BOARD AND ON HP MINI-ATX POWER SUPPLY. SYSTEM POWERS UP BUT NO HARD DRIVE SPIN UNLESS 80 PIN EIDE CABLE IS DISCONNECTED FROM P4B266-LA (Danube) SYSTEM BOARD. NO VIDEO POST NO VIDEO ERROR WITH TNT2-M64 32MB SDR AGP VIDEO CARD IN OR OUT OF SYSTEM. NO VIDEO FLASH ON MONITOR AND NO SIGNAL GROUND REPORTED TO MONITOR (MONITOR LED STAYS YELLOW). WHAT DO YOU THINK IS WRONG? POWER SUPPLY OR ASUS MAMA BOARD?
Tell me if there is something i need to know like: what were the things that you've doing with your computer before the problem happened?? are there any recent hardware/software changes?? tell also your OS- is it XP or Vista...

first, let's try to check if the problem is with the monitor or not,okey? try unplugging the monitor blue connector at the back of the tower.and make sure that your monitor is turned-on.If you can see a colored bars displayed.you monitor is okey.if not, try a known good monitor...if it woks the problem is with the old monitor.(resolved)
2 (if not)
Now, complelely turn off your computer and try reseating all the cables, and your hardware components such as memory,video card,IDE cable and so on. but before doing so, unplug the power cable and then push the power button to drain the power.after reseating everything, plug back the power cable and turn on computer.try listening to the tower,tell me if you can hear some beeps also.
if no video issue is still there, try putting a known good video card if you have any.if a known good video card works then the problem is with the old one..
if the problem is still there after everything that you've done try calling the manufacturer. this is lead to a motherboard problem but try to call them first.

As a PC tech with nearly 25 years experience, I have already tried all of these recommendations. All I wanted to know was if the ASUS System Board would beep if there's no AGP video in place or if a more familiar technician thought the prob was with the ASUS motherboard or the proprietary HP ATX mini-power supply......
HP pavilion p6210y. At power up Lights come on, fans come on, sounds like HDD comes on, but monitor says "No Signal". I'm stumped.
