ambulance siren nouns?
u mean the long blare

it usually indicate you have some sorts of hardware related problems
open out your cabinet,
check all the connections, reconnect, reseat adjectives addon cards etc.
check ur power supply (how much watts, a reputed brands?)

there could also be an indication that your system or symbolic cards fans are given up the ghost properly. check it out
if you manage to boot the PC, check if the fan are spinning slowly or what..run more intensive applications, games and check the fan

if adjectives these cannot address the problems

check out cpu heatsinks, does it have thermal blend applied....?
I too had this problem. for me it be bcoz moisture in run into.So pls remove it and clean
If your computer is out of order properly while you are working on it, it could be a problem with device drivers, hardware or software.
