Acer desktop running Windows 7 64-bit. Switched on today, black screens, one long beep and two short beeps. Loaded recovery disk, does not even spin as far as I can tell. Had the main board fail after 3 months, replaced under warranty in Jan 2011. I suspect it is a hardware failure and I'm going to have to take it in because I don't do builds myself. Pain, especially since they usually say 1 week to fix. Any suggestions / opinions? And yes, it will be the last Acer I buy. I have been thinking of a custom build so that I can run say 4 monitors, but that will have to wait for now. All the good stuff backed up every day so not too worried, only a ton of bookmarks I could lose.
