I have a dell inspirion 521(OLD but am trying to fix it for a friend)

I have a quick question about my motherboard I just want to know did it go bad because everytime I start the computer it loads pass the little load up part then is starting up and boom shuts off I downloaded windows 7 a long time ago on it and it took me so long just do that so I recently formatted it and then am trying to do it over I also did ram test with a software and then also took out the hdd and put it into my new computer it worked fine

So it wasnt ram/hdd/The power supply have yet to check probably will get one tomorrow but i dont think its that because i left it on bios screen the whole night and it stood so only things i think it can be is the processor/heatsink/ or mobo

So basically should i try to take everything out and put more paste on the procesor and buy a more modern heatsink with a more usuful powersupply

Make sure the PSU is OK, you can try another one in the system and see what happens. Do that first before playing with the CPU.
The heatsink should be OK if the system worked with it before, make sure the fan is spinning. All dust balls should be history, otherwise a thorough cleanup is mandatory.
When applying paste, don't add more; just remove the old one (alcohol swab) from the heatsink and the CPU, then apply a thin film (or a small dab in the center of CPU and press the heatsink to it). Remember, the paste is supposed to only fill the minute gaps between the CPU and the heatsink, not act as a third layer in between, because there is no paste that can match direct CPU-metal heat conductivity.
