Question about Intel (P42000400512SK478) Pentium 4, 2 GHz Processor

1 Answer

No display

I've just changed my motherboard and cpu to a ASRock P4VX4 with Pentium 4. Once turned on there is no display on the monitor. Is this likely to be caused by the processor being faulty ( I bought it on ebay from someone who said they thinks it works ok)?
When I changed back to my original board it works fine. Since the only difference between the two is the boardand the processor it leads me to think the processor is faulty.

    It doesn't make any noises, and as there is no display I can't tell if its actually doing anything. The video card works fine on my other board. If its the built in video controller is the whole board pretty useless?

    Yes the fans are all running, the hd led goes on for a while. Everything on the board looks fine. The card in the AGP slot works fine in my other board, should I maybe try a PCI? Can I rule out the processor, thats what I was most suspicious of as the guy selling it didn't seem 100% sure.

If it boots with no video, then it is a bad built-in video controller. If you get a long beep then its the processor.

    No, you can get either PCI or AGP video card adapter if it supports it.

    You say that you don't hear anything. Can you see if the fans are running?

    Check the capacitors for bulges and leaks. Thats a sure way to tell if the board is bad.

    Go into the Bios and set everything to default. Then see if the video works without your card if has a builtin video card.

Motherboard starts but no signal in the monitor

Hello here is the cpu list:

Other cpu`s than them on the list, does not fit the mainboard.
This will cause the mainboard not to boot up, when the cpu is wrong.
The (wrong) cpu will fit the socket, but it does not fit the cache size, fsb, and so on.

Look also in the manual:

The problem could also be the power supply failing, try to change that.

Did it boot up before you changed the cpu ???
Any beep codes ??

Look also at this page:

Good luck
