New Computer Wont' POST...

Recently I decided to put up a linux server from spare parts lying around the house.
KT7A-Raid, Athlon thunderbird 1.0 gHz, 512 megs sdram, 20 gig Maxtor hdd, floppy drive, hp cd burner 8200 series, ELSA Winner 3000-L PCI video card, and some generic nic card. Video card is in pci 1, nic in pci 6. 300 watt ps.
Computer refuses to post, gives a blank screen.

What are some generic things to check? I checked to make sure that everything was plugged in correctly, but have had no luck.
Just some of my ideas:
Maybe the PS of 300 watts is not enough. It's a Wintech Electronics Corp one. I tested by unplugging everything but motherboard (no cdrom, hdd, or floppy), and found that it still won't post. Any ideas on if you think this is enough power?
The cpu could be f*cked. It was once overclocked, and had quite abit of artic silver on it that needed scrubbing. I think a potential problem is that it is burned out, perhaps by bridging too many of those circuts on the top of the cpu. Artic silver was not properly applied and got everywhere. I cleaned with rubbing alcohol and nail polish, and scrubbed till silver taint was almost gone (I can't get it up anymore). I also undid the connections between the L1 bridges (I think it was done with a conductor pen, I just scrubbed with alcohol and a q-tip till it was gone). Anyone in Downtown San Jose got a spare socket a ?
Motherboard could be fried. Any surefire way to check this?

Please feel free to post questions and such, this server needs to go up very soon and I'm reaching a point at which I cannot deal with it anymore because of the threatening start of school in August. I also have a small budget, due to buying the case and other parts recently to get the box together, so I'm pressed for cash for things. For example, I can't just buy a new cpu to test it, and then find it was the motherboard, and then get a new motherboard. I'd be out of spare cash for this project by then.
If anyone has spare parts I'd be willing to talk about purchasing them for used prices, so help a fellow out. ;)

Thanks.

This same thing happened to me on my KT7A-RAID. I had the CPU fan in the wrong socket on the motherboard. The CPU fan would come on for about 1/10 second, then go off. Just check that. If it is in the right place, CPU or not, when the power comes on, the fan should spin. Also, if that doesn't work remove ALL cards except the video, and ALL drive connectors (you can leave the power plugged in, but if you suspect PSU, then unplug them too, 300 watt should be plenty.) I used a good 250 watt enlight PDU with SCSI drives, tape, etc... and mine worked for years that way. I went to a 300 when I upgraded to a Radeon 8500 just to be sure I had enough power.

Yes, on the KT7A-Raid, you must have a fan plugged into Fan1 connector for cpu, that is done.
When I turn computer on, fans run, and continue to run, Until I turn them off. ;)
Thanks for the reminder. No change in startup though. ;(

cpu is probly dead. if its still under warranty, RMA it, or you can get a new one.... they run only about 60 bucks at newegg.

Did you try unplugging all of the devices and the cards ? (except video) What happened then ?

1. Video plug pins are bent maybe?
2. Got a spare video card to try?
3. Does it beep when you turn it on? You can tell what's wrong by the way it beeps (see your motherboard doc).

When all devices are unplugged, it still will not display anything or give the stardard 1 beep from POST to notify things are ok.

It's DEAD, dude! :(
One last thing to check are the CPU pins.

What is dead, CPU or Motherboard?
What are your percentages either way? 100% cpu, 0% Motherboard?

I ask because if I buy new cpu, I can't afford new motherboard. :p
Tough to say, but give your guess a shot. :)

PS - I forgot to say I did check pins, perfectly straight.

no post codes, like beep,beep,beep ??? Try removing the CPU altogether, and see if you get a post code. It sure sounds like a dead CPU to me. I know you said overclocked, but was it working when removed from the last system ? You don't know anybody with an Athlon or Duron CPU that would loan it to you for 5 minutes ?? (with them watching if they wanted)

Hmm. Didn't know a motherboard would beep without cpu. I'll try it now.
No, I've asked everyone I know. They laugh at me and say only a nerd like me would ask for a spare cpu.
CPU was working last time I tried it.

Are you sure a kt7a-raid without cpu plugged in (but with fan1) will issue a beep code?
I tried it, no beep code.

You can also try your T-Bird in somebody else's machine.
Please also check the motherboard battery.
Is the internal speaker connected?
Check if the motherboard is grounded (I do not know for sure if KT7 has to be grounded, but it's worth it to check it out).
Visit KT7 FAQ and go to their troubleshooting section.
This part of it talks about boot problems.

Good luck!:D
