New processor, MOBO may be fried?

[acidcore]

I just got a new Intel Pentium 4, 3.0EMhz 800mhz FSB prescott core processor. I have an Intel D865PERL Mobo which supposedly supports this processor. When I put in the new processor it ran for about 5 seconds before turning off. So I decided that maybe the processor wasn't going to work after 3 attempts. I then put my old processor in and same thing. Turned on for about 5 seconds then died. Then I tried it again and it turned on for a good bit but was not giving any video to my monitor so I thought maybe the gfx card had fried. After it ran for about 30 seconds it then died. Then it never turned back on. I checked my PSU by using a paperclip trick and all my drives work but it won't give power to my Mobo. I was thinking the Mobo is fried since no powere is coming at all. Although the Mobo power light comes on, nothing happens. Please reply ASAP. Thank you. Any suggestions would be great.

First thing to do is HAL9000's troubleshooter.

Then try clearing the CMOS.

If you still have problems, try another power supply.

I took everything out connected it and still got nothing. I put everything back in the case, hit the power button and it powered right now. Thanks for the help.

I noticed in your thread that closed you stated that the HSF was the snap on kind and you didn't need any paste. The "paste" is not glue it is thermal paste and it stops your cpu form over heating. unless there is a thermal pad on teh HSF you need some paste. Next I think it is the PSU. Find one or get a new won 400 to 420 is all you really need. And test it. Test the ram one stick at a time too. Also see if you can find a spare video card to test the mobo. There are a number of things that could be wrong.

Being the impatient man that I am I decided to try to install my processor again. To humor myself I decided to reset the CMOS right after installing the new processor and *poof* it worked. I wasn't aware that you needed to to this and if so I am sorry for kind of wasting people's times. Thanks for all the replies.

you usually dont have to do that but it is a good trouble shooting method. It could be that you had to do that because you were switching processors. Im sure someone has the answer.
