psu issue?

604shizzle · 05-14-2008, 10:35 AM

My computer doesnt boot up soemtimes. When I hit the power button I see the green light turn on and the red light flash, and the fans turn on. But it doesnt boot up, and nothing comes up on the monitor. I have to hit the reset button a few times and then it will power up (sometimes that doesnt work and I have to keep switching it on and off).

I figured I needed a new PSU since I added a new 500gb HD, video card and soundcard, so I bought a coolermaster 750watt psu.

But I still have the same problem...

try a cmos reset
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer
go mto the ram makers site and check the voltage range for your ram you may need to up it manualy
