Oh sugar, now I've really bust it

OK back to as I was earlier, switches on, (No Bleeps as they are switched off) the fan is running and the fan on the video card, but nothing is going to the screen.

the screen light changes from orange to green when it gets a connection, and it stays orange, tried another video card and the same happens.

Have you checked that the RAM is seated correctly? (remove/replace)
The bleeps should come from the BIOS to give fault info, so how have you switched them off?

probably as my speakers were not switched on:o

GRRRRH! now will not switch on again!!!

I once fitted the heatsink and fan incorrectly. The computer shut itself down in seconds. Could yours be doing this?

The bleep sounds comes from a sounder on the motherboard, not the external speakers.

Check that everything is seated correctly and all cables are plugged in.

In that case - no bleeps!

I've pressed and prodded (carefully) everything I can think of, the memory is seated OK, all power connections in fine. Just dead now - think the switch may be duff.

I'm guessing that you only removed the heatsink/fan assembly and the CPU was left in it's socket on the motherboard? If not you may have not got the CPU seated correctly.

Although you havent mentioned. it's accepted you have checked all the connectors, removed, refitted etc.

You may as well remove the Heatsink again and also the CPU.

Hopefully the CPU is covered in a white paste but it is worth having a look at the core of the CPU

When they burn out (it would be a great world if they were always protected but sadly, it does happen) the corner of the core goes like this one:

if thats what you think it is, have you tried powering it up with a jumper placed over the pins for the on/off switch?

i've seen my mate do this before, but he did it with a metal screw driver :rolleyes:

My first thought was something CHR15 mentioned. The thermal paste/pad. New thermal paste/pad should normally be applied when removing and putting back a heatsink to ensure a good thermal contact and the old stuff cleaned off properly.
