Hi I have ahp pavillion 335w, just replaced the power supply , now when power up there is no post sequence booting and the power switch stays on all time and wont allow me to shut off puter. what could be wrong?
To shut the computer off, press and hold the power button. There might be something that's not plugged in correctly, so check all your cables, cards and memory.
I did that already, checked all the conections, it powers up but again no boot nosies or beeps , fans runing nad power button on locked. motherboard shorted out?
