My emachine T6212 http://reviews.digitaltrends.com/review/2630-4/emachines-t6212-review-specs
won't boot to the screen. I have tried rearranging the RAM, disconnecting the power supply except to the motherboard and no change. The fans spin and the on button lights. Is it likely the mother board or is therea way of testing the graphics/video card? I don't know how to tell what cards would be compatible and I don't want to put a lot of money in this computer. It is not used for gaming but mainly photo and personal storage, homework and home projects. I did remove the CMOS battery and replaced it but no change.
Also how do I use a multmeter to check the power supply?
