It was certainly a LOT easier than unplugging everything in mine and trying to figure out which bit was dead. I don't know how to test the CPU or the MB and I didn't like the idea of taking my computer to someone else to fix. I'm sooooooo glad there was an easier way, and Michael is pretty pleased with himself too, "I fixed mum's computer".
I asked at the computer store as to how the thermaltake psu could have damaged my computer, no idea. And apparently that psu has a cut off switch or something, so if it did get a surge or spike it would have cut off. Michael said that it was attached to a surge protector board and it was attached to a box with a cut off switch. He was using his computer went away came back and it was off, his mate didn't know why it just turned off, but after that it wouldn't turn back on. I'd like to know why, but thank god for a 5 year warranty. No more thermaltake, back to Antec. His old Antec 550 that he sold to a mate is still running well, should have kept it.
Lesson of the day, when it comes to computer parts, WARRANTY!!!!!
