Make sure the CPU is seated properly and the heatsink is properly attached and cooling the CPU...

I assume new power box is a new power supply. Why did you replace it? What did you replace it with?

[diamondrules929]

pc would not power up so i replaced the power supply with a new tiger 450 watt power supply

[shinybeast]

could be a bunk power supply, cpu, or the onboard video or mobo is shot. I don't recognize the beep codes. Was there really just two beeps?

Are you able to reach bios screen? Can you give me your bios name?

[diamondrules929]

i cannot get the key board to work , pc does not power up the key board

You have a board issue. Something wrong with the motherboard. Try to reset bios. And plug off all usb device from the PC.

Is there any way to reset bios without keyboard

http://www.computerhope.com/beep.htm Your system isn't going to do much of anything on boot up without the keyboard working. It's a basic part of the boot. Jazz

that would be morse code my friend. lol. that actually happens in mac computers, if anyhting fails it beeps out S.O.S

Yes you can reset bios without Keyboard. First, plug off power cord from power supply of the machine. Open up inside the PC. You will see bios battery on motherboard. Take off the battery and wait like 20 sn. After plug in back.

I'd suggest you find a standard keyboard and mouse or at least the adapters for the moment and try booting the system on basics. Jazz
