Ugh... New Pentium 4 System Problems!!

[amphibious]

I put together a Pentium 4 system last night, when I plug in power a little LED lights up on the motherboard, when I turn the power on the CPU fan goes on, the CD-ROM, and HD spin up, but the video card sends no signal to the monitor. The monitor works. Here are all the various configurations I've tried...

First boot up, everything is attached:
Topower 420w P4 Approved Power Supply
Intel Pentium 4-C 2.4GHz
Intel D865GBFL Motherboard
2x 512MB Crucial PC3200 DDR Ram
Western Digital 120GB HD
Cendyne 4x DVD+R
Cendyne 48x CD-RW
Matrox G450 32MB AGP Video
Promise Ultra133 TX2 Controller Card
D-Link 802.11b Card

So I remove some stuff and try this:
Topower 420w P4 Approved Power Supply
Intel Pentium 4-C 2.4GHz
Intel D865GBFL Motherboard
2x 512MB Crucial PC3200 DDR Ram
Western Digital 120GB HD
Matrox G450 32MB AGP Video

Same result... no output to the monitor.

Then I try this:
Topower 420w P4 Approved Power Supply
Intel Pentium 4-C 2.4GHz
Intel D865GBFL Motherboard
2x 512MB Crucial PC3200 DDR Ram
Onboard Video

So I pull the BIOS jumper, rejumper it, try again, no output. Pop out the battery, try again, no output. Now I swap around the RAM, all the different single and double stick configurations, no output with each configuration.

Now I go get another motherboard, it's an ASUS Xsomething... brand new, supports hyperthreading. I try it first with an ASUS TNT2 video card, no output... then again with my Matrox G450, no output. So now I try out some SDRAM from my old computer since this board supports SD and DDR... I just try one stick in the two available slots, no video output during power-up on either.

So I go return the motherboard and get a new processor (this time a 2.6GHz P4-C, pop it in the Intel board with the bare configuration (PS, CPU, RAM, onboard video) power it up... STILL NO VIDEO OUTPUT!

So now I know something is massively wrong... What the heck could be the problem? Somebody suggested the apartments wiring... The apartment I live in is 80 years old, but the power has never been an issue before, I am a musician and I have two 12u racks full of synths that I use all the time. Could it be the power supply? I does power up the HD, CDs, CPU fan, case fan, etc...

Anything else I could try? I think I'm going to try to use the power supply on my old system and see if that could be it... but in any case, I'm totally stumped any leads would be awesome.

Oh, I forgot to mention, 2-3 pins were bent on each processor. I used a toothpick to put each bent pin back in place... I don't know how much of an effect this will have on the CPU, for the older larger pinned processors it didn't matter much at all.

please... somebody respond to this, I really need help here...

Hm, this sounds similar to a problem I was having recently with my new computer. I ended up replacing the power supply with a bigger unit (more power) and everything began to work properly. In your case I'm not sure if thats the issue but I would be willing to bet its either that or the video card itself. Does your motherboard come with onboard graphics? If so you might want to just try to use that instead of the video card so you can narrow down whether its the video card or power supply. Hope that helps some.

P.S. I highly doubt it has anything to do with the wiring in your house, but thats just my opinion.

Yes, I've tried the onboard video and both AGP video cards I have. The power supply is a 420W P4 approved supply... it doesn't really get much bigger than that does it? :-/

 

[Afro000Dude]

It's a working monitor that doesn't work with at least three different video cards... Are you sure it's a working monitor??

 

[amphibious]

Yes, I've been using it for years... in fact I have two of them, both of them work on all my other systems and when I hook it up to this new system they just flash No Signal.
