Question

i have a intel pentium 4 630 3.0 GHz (LGA775) with 800MHz FSB processor. a MSI 865PE neo 3 mobo, 1GB dual Channel DDR400 (2X512.x16) a Sapphire radeon X1600pro with 512MB GDDR2
a 80GB Raptor SATA Hard drive. and a 300W PSU. it will not even try to fire up...do you think it's a bad mobo? or just not enough juice? there is no power at all.it connected right...the psu is good..all the hardware is new,eccept the mobo.i thought it would at least supply power..and run really crappy but it does nothing! can you help me PLease ive tried every thing!

Answer 1

Every pc I have looked at has a little switch that turns off everything going into the pc. It is usually located on the back near the main power cord. Be certain it is in the "-" position. It looks like a minus sign. The "O" position is OFF. If that is correct then try unplugging everything in the power supply unit and just plug in a light or some other thing that uses power. Power supply units can just suddenly die, mine did. It let out one long screeching beep and the pc went dead. If the psu will work one thing, try plugging your other units in one at a time to see if it kicks off. If it shuts down you will know it just can't manage all of your components.


Good luck

Did you recently add any new devices to it? If not typically it's mobo or power supply. Power supply is cheaper so start by replacing it.

Also make sure the power button is actually hitting the internal button. I sometimes take off the face cover of a computer and hit the internal button just to make sure before I start replacing crap.
