HP Pavilion a810n. Green power light flashing , computer will not start.
Power getting to the computer/Power Supply?
Yeah.
Power Supply good? -> NO
A) IF ALL of the LED lights were on at once, they would use less than 1 Watt of power.
B) EACH fan uses 2 to 3 Watts of power.
C) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.
HP Pavilion a810n Desktop PC?
Uses an AMD Athlon 64 3300+ processor,
(Operates Up To a frequency rate of 2.4GHz)

http://en.wikipedia.org/wiki/List_of_amd_athlon_64_microprocessors#.22Newcastle.22_.28CG.2C_130_nm.29
Can use up to 89 Watts of power.
Your Power Supply doesn't even have enough power to spin fans, much less start the Processor.
Want to test the Power Supply? Have a multimeter?
No? Have a power supply you can borrow for a test unit?
KNOWN to be good, and Compatible?

I had a similar problem. Moved a 4-year-old desktop. Got the flashing light and no start. Quick fix is to unplug unit, open up case and unplug the large power connector on the motherboard. (On mine this is marked P1 and has a lock tab on one side that must be held in while unplugging.) Plug the 110-volt power and THEN plug the connector back into the motherboard. Button the case back up and all will be well until the next time you shut the power off to the computer.
The cause of this problem is likely that the battery on the motherboard is nearly dead. The flashing light is a warning to replace the battery. (It would have been nice if they would have put this into the user manual.) When you disconnect the power as described above, you interrupt the low-battery circuit. Replace the battery and all should be well.

SOURCE: hp xw6200, 6 beeps, and red power button...failed start up.
6 long beeps indicates that there is a problem with the memory, take them out, clean the contacts and the DIMM slots and reseat them.
Hopefully this will resolve the problem, if not new memory may be required
kind regards
