Last night my computer powered off randomly and now will not power up at all. When I press the power button I get a slight flicker but then nothing. I removed all the components one-by-one and still nothing. I then removed the JPW1 motherboard connection to the power unit and the comp powers up (but without graphics card etc). Does this mean the motherboard needs replacing, or is there something less expensive wrong with the comp?
Motherboard - MSI MS-6565
