SOURCE: 3 beeps and fan running at start up

The three beeps shows the Memory Module Test and that symbolise that the memory module is having a problem and to my knowledge when there is a problem with the memory then you have to open the casing and remove the memory module and clean the slot very well and if slot in back and the memory do the same change the to the second memory slot if it happens there again then you change the Memory module.
ok
rate this solution.

SOURCE: it wont stay on

probably bad memory, 256MB DDR (PC 2100)

SOURCE: Compaq Evo D510 Space Saver PC Desktop network drivers

We had the same problem and tried all of the drivers & even the expired link here, but then went back and discovered the PRO 100 drivers contained in the HP Intel PRO/1000 GT drivers download
file sp33671.exe (64 MB), 9.4.21.0 A (4 Sep 2006). Choose to extract to a non-temporary folder, it will produce C:\swsetup\SP33671\PRO100\Win32\ by default and that is where we found the driver. Hope it helps!

SOURCE: computer tower started beeping

If you added more memory this may make your tower beep.
If so I WOULD REMOVE THE ADDED MEMORY AND THEN RESTART

Try replacing the RAM (Random Access Memory) Stick

Thanks
