This comes back to the PSU again, possibly the supply from the PSU to the MB, what happens if you leave the Ram in but remove the video card?
I took them both out and powered up however it's just spinning once and stopping again. I put them back and I'm getting the same. All day it's been rather doing this or bleeping??
What about this from post #14
Have you checked if there is also a pci-e slot on your sisters computer that you can put your card in instead of using the onboard video.
Is there no pci-e slot on the other computers MB, it is possible it has onboard video and an expansion slot.
EDIT: Rather than going around in circles I feel the best suggestion is to do a bare-bones set-up with the MB out of the case and the minimum amount of components fitted, see my canned text on how to do this below;
Best couple of suggestions I can make would be first remove the MB and do a barebones set-up on a piece of cardboard (make sure it is larger than the MB) only connect the PSU, the GFX card, 1 stick of Ram and the keyboard.
You will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding a component, second suggestion try a known working PSU (your sisters), third suggestion try and loan an ordinary PCI graphics card (not pci-e) again to try and get a BIOS screen.
Whilst the MB is removed from the case take the opportunity to clean out all heat trapping dust from inside and check that the HS below the CPU fan is not clogged with dust, if it is it will cause the processor to overheat which then forces a shutdown to protect the CPU, again see below for my canned text on how to safely clean out your computer;
If the computer needs cleaning out, first remove the power cord from the wall and open up the case, take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case, remove the video card, blow out the slot and re-seat the card securely, do the same with the memory sticks, clean all internal fans, if you use canned compressed air do not let any fan spin freely this can damage them, use something like a clean lollipop stick to hold the fan. Make sure all internal connections are secure and that there are no loose components, write down the psu details (make and model) re-assemble the computer, boot up and see how it goes.
