Q: iMac mid 2010 suddendly does not start anymore

Hi all,

 

I was working with my iMac a few nights ago, when it suddendly rebooted.

When restarting, it tried to boot, but while on the Apple white screen, it rebooted automatically again. Did this two/three times, when I pressed continuosly the power button to stop the process. Then, I disconnected the power plug. The following morning I tried to start it again, but it didn't do anything. No sound, no display. If I listen carefully to the back, I can hear the hard disk start and the fan start (not at full speed). But the iMac apparently does not even try to boot. No chime sound at all (even at low volume - I managed to lower its volume months ago...).

I tried everything: unplugged all the devices, leaving only keyboard. I replaced the RAMs with the original ones... No luck.

What can I do?

 

Thank you in advance,

MyFire

iMac (21.5-inch Mid 2010), OS X Yosemite (10.10.4)

    Hello MyFire,

     

    Welcome to the Apple Support Communities!

     

    I understand that after rebooting on its own a few days ago, your iMac will not turn on. It sounds like you have completed some good troubleshooting steps already as well. To continue troubleshooting, I would suggest reading over and working through the steps outlined in the attached article below. If the issue continues, it may be necessary to visit an Apple Store or Apple Authorized Service Provider as discussed in step 7. 

     

    If your Mac won't turn on - Apple Support

     

    Best regards

    hi joe,

     

    in fact I followed all the directions with no luck.

    So I brought my iMac at the Apple Store. Initially it seemed a motherboard problem. Finally it was found to be a video card problem (so much better from an economic point of view).

    Now I am happily writing from my iMac

     

    Thank you for your support!
