i have a problem about booting my computer and it realeses a beeping sound inside my casing i dont know where it came from.It all started when i change my psu to 650 watts my previous psu is 250..I change my psu because my gpu requires more watts about 400 watts.I also bought 4 gb ram to add more power to my computer.After i put it all together in their places and i turned it on it realeses a beeping sound inside my computers casing and theres no display in the monitor.Please help me!!!!(sorry about my grammar hope you understand what im saying)
 
is it just one short beep or a prolongated one? if so is it followed by more beeps? the beep is a code to let you know what piece of hardware is preventing the system to properly boot (1 short beep = all fine, other beep = something is bad).

You need to first determine the exact beep sequence in order to fix the issue.
