No display, mb/bios prob ?

Enjoy the site greatly, first time post. Having problem with a :
P4 2.53 / ASUS P4B533-VM
w/ 512 Mb PC2100 DDR (all new) .

Besides the DDR stick, there is nothing installed. I start up the computer, and my monitor remains totally blank. The internal light turns on ok. I plugged in a keyboard at one point, and the lights flashed on for a second. No sounds emit ( no beeps ). The ps runs 115W and 230W. I'm wondering if that's enough for a P4.
I bought this as a kit, pre-installed. I am having a heck of time trying to get any tech support from the company. I hope somebody can help me out w/this. I appreciate any comments, assistance, or laughter. Thanks!

one more thing, the fans start up w/ I power on. And the specs on the motherboard support the RAM.

Welcome to the forums pbot..........................:D

Take a look to see if the dip switches are set like the following.

And is the ATX12V four wire connector coming from the power supply hooked up here?

The DIP switches are in Jumper Free mode right now. The heatsink fan is plugged in, however the ATX 12V is not. The ps doesn't have a corresponding connection for it. Not enough power, eh ?
thanks

You should be using a P4 compatable power supply with the 4 wire connector. I'm not sure if this is the answer to your problem but it very well could be.

Some P4 motherboard manufacturers don't even use this plug but I would imagine if it's there it should be used.

Try a new power supply that's P4 ready.................:D

out of curiousity.... after you turn it on.. you said you noticed the keyboard light up briefly.. and everything else acts like a boot right?
just no display...

At this point (20-30 seconds after you turn her on) does hitting capslock or numlock change the key light?
And if you mash ctrl alt del a couple times does the machine appear to or nor care?

(just trying to find out if it truely is not booting or if she's booting fine just not outputing your video...)

better yet.... does this motherboard have on board video? (looks like the specs say it does...)...

If by chance you are using a video card you put in the AGP slot... (and it DOES have onboard) the problem may just be bios booting the local first... (pci before agp?)

But of course I'm sure you would know to try the onboard port if it had one....

I've hit alt-ctrl-del, no response at all. I'm currently using the onboard video, but I may try plugging in a video card to see what occurs.

Since you don't get any beeps, you aren't even getting as far as the video check, so I doubt it's the video board. My guess would be the processor or MB, but I'd check the memory in another system just for kicks... I presume the speaker is plugged into the proper pins, right?
