Maybe my switch is bad on the 800d?
Any ideas on what to test to try and fix this??? Thanks
I am thinking/hoping a bad switch is unlikely considering this case costs close to $300 and is supposed to be of the absolute best quality. Plus a bad switch is a pretty uncommon problem, considering how simple an on/off switch is to manufacture.
First I would try putting the motherboard in a different case (assuming one is available to you, most computer people tend to have at least one lying around I think.
If that doesn't help, it is possible your motherboard, CPU, or RAM may be bad. All three of these can prevent a computer from turning on completely. Though if your RAM was bad your motherboard should light up at least. Try possibly using a multimeter to check if the motherboard is bad. Make sure everything else other than the RAM, CPU, Case, and PSU are disconnected from the motherboard. If the motherboard is not dead you have it narrowed down to the CPU and RAM. Try using one stick at a time for the RAM to narrow it down. If that also has no effect, then I would guess you received a bad CPU.
Hope that helped a little bit for you.
