    PC won’t start

    Locked

    by hefty10 ·

    Hello
    Could someone help me please.My friend has an AMD 1200 or 1300 CPU with 315 mb RAM,40 gb HDD,onboard video and sound.It recntly stopped working for no apparent reason.It will not start.There is power going to the monitor from the PC power supply but the PC will not start.I tried the power supply in a similar PC and it worked 100%.
    I then tried going from the start(no hdd,floppy,etc)and building up,but no go.I tried different RAM in different slots,but it still does not work.There is not even a BIOS screen.
    I came to the conclusion that the motherboard had died,so I bought an ASUS P4S800 motherboard,a Pentium 4 2.6gb CPU and 512 Mb ddr ram.I swapped it into the case with the same hard drive etc and the exact same thing happened,nothing.No bios startup screen or anything.There is power going to the board as some small lights on the board come on and the power lights on the DVD rom and the burner come on,but nothing even tries to kick in.It is silent.Could someone tell me what the problem maybe and how to fix it please?
    Thanks
    Steve

      man… in that situation, the only thing i can think of is…

      ba ba ba bum…

      THE MONITOR!!

      make doubly sure the monitor is getting power, try the monitor on another computer, maybe that’s it?

      On the new motherboard, check that the clear CMOS jumper is NOT in the clear position.

      Many motherboards do not start up if the jumper is set to clear.

      Another item to check, is that the video card is FULLY seated in it’s slot.
      AGP cards have interleaved contacts, and must be fully seated for all connections to make.

      Hi,

      You stated that you installed a new mainboard and P4 cpu. Is the power supply P4 compatable does it have the 4 pin plug for P4 cpu power?
      The Asus P4S800 mainboard has the P4 power connector on the board. Did your ps have the 4 pin connector on it?? I don’t know if this will help, But the P4 won’t run without it! I hope this may help you.
      (you didn’t state what ps you have)

      Regards, Gil

      Usually this is a BIOS problem in the video card.
      The Video Card has a BIOS on it.
      The PC passes control to it at the very beginning of the boot.
      If the card loops or crashes, rather than not responding, the boot hangs.
      If the card does not respond, then the PC BIOS issues a beep code that the Video Card is bad.
      (Most no response errors are caused by the card being improperly seated.)
      The obvious troubleshooting test is to try a different “Known Good” video card.
      Regards, Chris

      Hi

      if you bumped the pc and shorted the MB to case this would happen

      Start with original set up and do a bench test out of the case with only wideo hooked up and see if it screens

      do same with second setup

      If no screen then MB or CPU is dead

      it only takes a darn little short to MB standout to screw things up

      Make sure you aare “static” guarding at all times

      Two people in one machine at same time is a static disaster or even handing parts to another person is a static disaster without the proper precautions

      This has to be something so simple. You stated that there is power going to the monitor from the PC power supply, but the PC will not start. Why is the monitor getting power from the PC power supply? One other thing. Is this all plugged into a power strip that might be faulty??

      good luck

      Trying checking the connection to the reset button or power button. I ran into a problem where the monitor is working and I know the PC is trying to boot. The reset button could be stuck and all is needed is to reconnect the wiring to tht MB.

      Good Luck!!

      Try building the system outside of the case on the bench. I use the motherboard box for a base for the main board and the cards can be slid down into the slot on the top of the box. If you look at the book it has the pins to temp jump to get the system to start. Only connect memory and video at first then install devices one at a time. If it works on the bench perhaps there’s a grounding issue with the case.
