Computer won't boot.

[squeezi]

So I was switching out the fan the other night because it was beginning to slow down due to dusty bearings or something. I installed the new fan and suddenly my computer would not boot when i turned it on. I realized that my CPU had bent pins so I figured it was that. I took the opportunity to switch from AMD to Intel. I went got a new Mobo and a new CPU. After switching these two the computer still won't boot. I'm pretty sure it's not the video card, and I don't think it's the power supply. Any experienced techies know what it might be?

The graphics card, fans, hard drive all get power, but nothing shows.

I'm positive that all parts are compatible.

which fan did u switched? case fan ? CPU fan?
what about some peeps when you turn it on ?
do you get any ?
the speaker is attached to the mobo ?
have you thought maybe you haven't insert the cpu as it should be ?
or maybe you bent up the pins by using to much force to inserting it into the socket ?

Best Regards,

I switched the CPU fan. No beeps when I turn it on. Not sure what you mean by the speaker is attached to the mobo. Pretty sure that the CPU is inserted correctly. And no I didn't bend the pins by forcing it into the socket.

Hmm, I've had problems like that in the past. It may be a problem with the new motherboard and the case not agreeing on the grounding. Course, it sounds like it is actually staying on, so that's probably not it. The other rather basic thing that is easy to overlook is the CMOS jumper pin. It is possible it came in the box on "reset" mode. The computer won't boot when the pin is in that position (usually). Verify the CMOS jumper setting is on "normal."

Also, don't know if the board has onboard video, if it does, it may be defaulting to that first? If applicable, try plugging the monitor in there.

Saying "didn't bend the pins," so I assume a socket 478 CPU? Simple things would be to verify the 12V+ connector and the 24 pin power connectors are properly attached.

Some other random things to try: Try to boot with no RAM, sometimes that'll get it to at least beep at you and you know your CPU is good. You could try building the computer outside the case to test the grounding issue; just build it on a table, should work just fine.

The Speaker attached to the motherboard reference is the small four pin wide connector, though it probably only has two wires, that goes to the motherboard in the same grouping with the power/reset switches et al.

Well, got a little windy, but hopefully something there helps.

Cheers.
