I'm troubleshooting a friend's computer who thinks it got hit by lightning. I figured it would be a quick power supply swap, but the computer powers on and makes constant siren noises. I've gathered that this is a sign of CPU overheating, but how can it be overheating instantly after powering on? Should I just swap out the processor or check something else first?
 
sirens are usually dead CPU or dead RAM. Basically, the two main things you need to begin booting, and if it can't find them it whines.

May also try a different video card, but it's most likely CPU or RAM.
