If it runs for a while and then starts doing this, it's likely overheating. Modern systems have a thermal safety where the processor itself will deactivate above a safe level. Check the vents and clean them out with canned air. If that isn't the case, first disconnect any and all external devices (including USB nubs, etc) and try powering it back on. If that doesn't fix the problem, try removing all but one RAM stick and removing the hard drive and CD/DVD ROM. Try turning it on then. If that still doesn't work, remove ALL the RAM and check for a beep code. If you get one, you know the motherboard is at least still working enough to give a no-RAM code. Try alternating the RAM sticks to see if it works.
