My Mac Pro is receiving power as are the monitors, but when I startup the power light immediately starts blinking on the tower and does not stop. The fan powers up in this mode for sure b/c you can hear it, however the monitors do not. I've tried resetting the PRAM on startup, but it immediately goes to blinking light mode while doing that as well. cd/dvd tray won't open either, so can not try to startup from disc. Any advice? Mike

Thank you for the response. I have after market RAM, I bought from Other World Computing; however this RAM has been in the computer for a while without problem, probably 6 months since last upgrade. I pulled each and re-seated them, then tried powering up with no luck. I even pulled one altogether and left the other set in and still no luck. Advice from here??? Mike
