T-bird processor problem

I installed a AMD T-bird 900Mhz on a Biostar M7vkd motherboard. I used a heatsink and fan that was for a socket 7 instead of a A socket (I had it on hand and it fit) and heat sink compound. Computer never successfully booted. There was no POSTbeeps. Power supply runs, processor and chipset fans run, no video, and the floppy light stays on.
Service tech at the store says I fried the processor because of the wrong heatsink/fan. I think it should have at least booted before the heatsink/fan would had been inadequate. Is the tech correct or did I get a defective CPU?

While it is true that an AMD processor will fry before it gives you any warning, I do not think that is the prob. However, you say your floppy light stays on? Turn around the ribbon cable on the floppy, that just might be the problem right there.
Good Luck!

The floppy cable will only plug in one way ---the connections are both notched. I unplugged the ide cables and it didn't make any difference.

Disconnect all the data cables, floppiy and IDE, turn it on and it will start. The problem is you have at least the floppy data cable in wrong positition or make sure that the ribbon green on the floppy cable goes to the pin 1, but it is easy to figure it out, if the light of the floppy, cd rom or hard drive stays on it means it is upside down.

Your processor is just fine,

Give it a try,

I also agree with the above replies. Your CPU should be ok for now, chances of it getting overheated are high if you keep using the socket 7 heatsink.
Firstly, Socket 7 CPUs are slower so they generate less heat than Socket A CPUs. Secondly, Socket 7 heatsink/fans are designed for socket 7 CPUs.
Therefore the heatsink/fan you are using may not be able to dissipate the heat away from the CPU fast enough, even though it fits. My advice to you is to invest on an AMD approved heatsink/fan (check it out at www.amd.com), which is much cheaper than another T-bird CPU.
