[ltpimp]

Hey guys

today i just built a new pc for myself

AMD phenom II x4 945
Gigabyte GA-M720-us3
Powercolor Radeon HD 5750
4gb DDR2 800 Kingston
in a ThermalTake v3 case using its default power supply atm.

i when try to boot it up, lights turn in, fans spin but then i hear this constant beep coming from the speaker then a solid beep, its not the cpu in a bad spot coz its simple to put it in, can any1 help me think wat the problem is?

check the manual of your mobo, it will explain what the beeps mean
(bad/no gpu/ram/cpu/...)

This is a good guide on boot issues. Check everything on this list one at a time and double-check everything is connected correctly. Post back here when you're done and we'll go from there.
