5 beeps = Pre-video memory error which means that the northbridge on the motherboard is faulty. You need a new mobo, this one is dead.

5 beeps for an AMI BIOS, which I think you have, means you have a processor error, or, in other words, the CPU.
Just to be sure, disconnect everything BUT the video, CPU, and memory. See if the result is the same.

software best guess-
-you have gotten a virus that is affecting your system files.
-your system files have been damaged.
do a good scan with some virus protection and remove the viruses
- if it shows viruses affecting system files-and that virus cannot be removed by any regular virus protection.
try watching a few combo fix tutorials-last resort for a malicious unmovable virus.
hardware best guess-
sounds like an overheating issue try buying a good case fan.
if that does not work try removing your heat sink from your processor wiping both clean of paste or residue and re applying thermal paste. my favorite type is arctic silver
