Right I was upgrading my pc, put in 2gb ram, turned it on everything fine.
put a new graphics card in turned it on - fine
put new hard drive in- fine all formatted ok
changed the cpu....
Fisrt of all there was 1 long beep, 2 short beeps, which is apparently a video error so i removed the new graphics card, started it up same beeps again, went to the mobo manufacturers site they told me to clear my cmos, which i did. Started it up again, same beeps.
Decided to put the old cpu back in, and now it starts normal beep. but it doesnt start booting it just sits there with the name of my mobo on the screen.

Mobo asus m2npv-mx

help?!

Clear your CMOS again with the new CPU in. I once tried to test a CPU on a PC and it killed the mobo. I could never even get it to power on again.

You need to be 100% sure it's compatible with your system board and that the BIOS can support it.

You should be able to see what is happening and if the M'Board is telling you anything.

Also did you remember to reset the CMOS?

If it's been cleared and not reset the computer is unlikely to boot.

how do i reset the cmos? put the jumper back if that's what you mean?

by oh smeg

Or something similar. Press the mentioned key and when you are in the BIOS Setup turn off the Makers Logo and set the Date & Time at the very least.

If you have not done this the M'Board defaults to the original Date and midday time so it's possible that the System Date as listed in the Real Time Clock is older than the Windows Files on the HDD. If that happens Windows can not load as it's not possible to boot a system before the files have been written.

Can't beat Computer Logic here but if you want to see something really funny set a date of 2025 and see what happens. :D
