I have had this PowerMac for ~6 years and over the past year it has been getting worse and worse about booting. I have to entirely unplug it from any power source and then push the power button a couple times, then reconnect the power cord and power it on. Most of the time having to repeat this process 5 or six times just to get it to power on. I believe it is the power supply going out but wanted to see if there is something else I should be doing to know for sure if it is the ps or something else. Also just recently (within the last ~1 month) it has been dying (turning off) without me shutting it down and without there being a power outage or spike. I have it on a protected outlet. Any ideas?
