Hello. I have a late 2009 iMac running Windows 7 via Bootcamp. After running perfect for several years, I turned it on this morning and am receiving a black screen. Restart the iMac and then I might get a white screen - regardless it is not booting up in either the Mac side, nor the Windows side. Any and all suggestions are welcome.

Doesn’t sound good here ;-{ You’ll need to open the system up and then check the diagnostic LED’s Technique: iMac Intel 24" EMC 2134 and 2211 Diagnostic LED’s. Tell us what you see.
