Why does my computer not start?

Question

I have a S6900NX, the power supply went out but I didnt know and in the investigation I broke the cpu chip and so I replaced the power supply and instead of an Athlon3200 I put in a sempron3000 (both s754). Ok I also put in 1gig geil ram 2.5 latency. all drives stock. and gpu stock. When I try to stasrt it up, everything powers then restarts, and it repeats this over and over. I took everything out seperatly and the only thing that caused a difference was taking the cpu out, what can I do to fix my problem. I will answer any questions because I really want this to work.

Johnny I did what you said to do with the motherboard and I got 0 beeps with everything taken out. Must be the motherboard then.
And to the other people, of course I put it in right (that does not take a rocket expert)

Oh yeah, and the it does not even get as far as the bios screen, nothing comes up on the monitor, it just keeps restarting and restarting, never getting to the bios point.

Answer 1

Sound like the mother board is not posting, you need to check to make sure the cpu will work with your board. Did the PSU take out the board, it is possible. remove everything from the board and turn it on and it should give a numer of beeps, if not replace the board. Repair tech in business for over 15 years, and thats how you check the board if you don't have the equipment to do it.

Answer 2

Does your motherboard specifically state it supports the sempron3000 ?

You should try a repair install. You may be missing some files for the new chip.
