This problem have been a while now. Every time I power on my laptop (Acer Aspire 4736zg) it shut down when booting up (windows loading screen) and it really means SHUT DOWN not freeze or restart ... It likes losing power. It only works in safe mode. Windows 7,8 Setup CD can't boot up (shut down just like above). I have done everything: fixing driver, scan for virus, chkdsk, update BIOS even install new windows ... The problem still there. I have tried install Joli OS (Linux) for a chance but not work (still shut down).
At this point no matter what the issue is it's going to need repair. If it's happening with more than one OS that pretty well eliminates the possibility of a software issue. I would still say that it's likely overheating, or there is an issue with your graphics adapter. Regardless you'll need to speak with Acer on this one.
