Hi all, In the past I was having problems with my pc just crashing and eventually it doesn't turn on. The motherboard light is on, fans work, I can hear the hard drive working but there are no beeps. I just bought a new cpu and for a while it turned on then it would crash as before and now it doesn't turn on again. My suspicion is that it's either the motherboard or psu but with the graphics card fan, cpu fan, motherboard light are all still on so I doubt it's that. I am going to order a new motherboard or psu can anyone suggest which I should do or alternatives? Thanks My pc: Intel Pentium 4 Northwood 2.8 GHz (478 socket) 1Gb ram 360 W psu NVidia FX 5200 graphics card motherboard is Asus P4P800 2 Hard drives, 125 MB each (roughly) Also things like unplugging the HD, graphics card or RAM doesnt do anything, still no beep..etc. When I first got it to work after buying and installing the new cpu it was saying it wasnt detecting the cpu fan, but I dont know how that can be since it was running fine.
