Computer Won't Post...

So, this all started months ago when my parts arrived, and I set about putting them together. As expected, the thing didn't work when I powered it on. It wouldn't go past the post screen. I got some help and managed to get it to install Windows. I ran it fine for awhile until I realized that the RAM was in the wrong slot. I moved the stick to the appropriate slot, and everything went downhill from there. So, after a lot of tinkering, I gave up and sent back the motherboard and RAM. I would have sent back the CPU, but it was overdue, and I couldn't. I recently recieved my new RAM and motherboard, and I put the computer back together, being careful about which parts I put in first and wearing an antistatic band. When everything went in, I powered it on. It didn't post. Nothing on the screen. No beeps telling me it had passed POST. Just a single red LED and a single green LED.

Now, I have 2x 1GB Mushkin RAM, an Abit KN8 SLI motherboard, and a radeon X1600XT. I used the shadow card in place of a second card, since I don't have one. There was a bit of thermal compound that got on the socket, but I cleaned that off, and reseated both the RAM and CPU. Still the same result. Won't post. Checked the jumpers, cleared the CMOS, nothing. Not working. Can I get a little help here? I want to take it to a professional, but I don't have a job, let alone money.

Try clearing the CMOS. Is the shadow card in the PCI-E slot 2?

Yes, the shadow card is in slot 2, and I've tried clearing the CMOS. I mentioned that already. Ugh, this whole deal is why I never liked PCs. I've been a Mac user for years, but their limited game library has forced my hand.

Are the any beeps? I tried going to the Abit site twice tonight for the beep codes but it looks like their site is down. What does the manual say about beep codes for the POST failures?

No beeps, no nothing. Sent a current through the beeper, and it's working. I've just been informed, though, that my ATI card may not even work on an SLI motherboard. I set it up to run in single card mode, but that might not be enough.

Here's an email the guy who is working on the computer sent me:

Well I made some progress. I tried powering on the system with no RAM installed. The thing gives a long beep every 3 seconds, typical error code for no RAM found. So that tells me that MB and CPU are probably working.

So I tried each RAM individually in slot 1. No beeps.

So I'm pretty sure it's dead RAM. Looked at the Mushkin site for tech info on this MB, didn't find any. Registered for the forum so I could post some questions but have not gotten my account activated yet.

Gather up your purchase receipts, order forms, whatever for the RAM. Let's see if we can get these chips replaced for free under warranty.

We found out what the problem was.

Posted Image
See the white scratch mark on the PCB? It starts right where that metal prong of the heatsink is and runs straight down to the damaged pin. And you can see fiberglass residue on the tip of both prongs on each side of the heatsink. The heatsink was pushed down, this prong slid along the PCB leaving the scratch, then broke the pin.


Yeah, turns out he did that when he pushed them in the first time. XD
