Guys need your help/advise, I've got a problem, couple of months ago I've installed SSD to my 21.5 iMac mid 2011, everything smooth, no issues. Installed Windows in partition and played some games on it (like Diablo 3). For a few times I've experienced that system stuck, and reboot by it self (in Windows), after that it will restart right away as normal. But today with the same thing, and I can't turn it on. After pressing the "on" button, I can hear cooler/HDD/DVD sounds, but there is no start up chime and no response from screen (just a blank screen). Yes, I've left HDD and super drive with SSD. Most of the posts online suggest to reinstall RAM (I have 16Gb, but it installed over a year ago, no issues), I've tried it, same thing (even with one module at a time). Other common comment to hold Shift+Option+Command+something, to reset something. I have bluetooth keyboard, which obviously is not responding, I got another wired one, same thing. However, my wired mouse blinked when I'm trying to turn on the system. I guess USB port is alive (as well as mother board, I hope). The question, should I try to take off the SSD or try another monitor or so? I guess it could be burned GPU, but I have no idea how to check it without another 100% working... Any help will be really appreciated, thanks in advance.
