Help. PC doesnt start after cpu change

Make sure you plugged the CPU in the right direction, and take off the CMOS battery for a few minutes, and make sure you're using the latest BIOS.

Then try the CPU in another supported motherboard, if it works, then you need a new motherboard, if not then your CPU is dead.

Me, there is one thing i CANNOT understand. How can you run an ATI x1950 pro with a 240w psu? Hell, my old x700pro needed at least 300w to run stably! But i would do to things first. Like Regen said, try the CPU on another board, and try connecting a higher rated psu. For x1950 pro, would recommend 470w or more.

it works. that psu works great. but probably not with a 3700+ cpu (more powerful than 3000+)

ill try 3700 on another board. if it doesnt work, ill buy a new barebone (love them)

PSU is to weak.

your video card saps between 70 and 90 watts
that cpu saps 60-70watts

then you have to take into equation hdd's. fans, optical drives, onboard devices, such as lan, usb, audio.

any addin boards also up the power requirement.

Yeah ... him psu are too weak first but secondo his board dont support the cpu ... So ... anyways ... Well i think really he needs an new psu ... :P
