What model PC is it?
Normally 5 beeps with red flashing power light, pause, 5 beeps means there is a memory problem.
Remove and reseat all the memory modules.
If after doing that you still get 5 beeps, you need to remove all of the modules but one, and test each one until the PC boots up. Then you will have isolated the bad memory chip(s) and it will have to either be replaced or you will have to do with less physical memory.
