Question about Dell Dimension C521 PC Desktop
Many things can cause this but my suspicion would be RAM.
Try shutting down the PC, turn it off at the back on the power supply and remove your RAM.
(Leaving the PC plugged in, means you can touch the chassis with both hands and earth any static you may have in your body)
Use a small vacuum cleaner or brush to clean the RAM and connectors,
refit your memory and try it.
NOTE: You should not have to push the little locks into the ends of the memory. If you put them back in carefully and press them in correctly, the locks will go in by themselves as you push the memory into place. If you can, support the motherboard from underneath to prevent cracking it.
