Hello richardapayne Sounds like a driver, a memory problem (not to sure why other OS’s work though) Does it restart at the same spot during the installation? If yes what is the installation doing at this time? I would try running memtest86 for at lease 5 passes (I leave it run all night.) http://www.memtest86.com/ When in Lunix run psensor to check your CPU temps. When installing Windows the CPU can max out and if the CPU gets to hot the computer will reset or turn off. http://wpitchoune.net/blog/psensor/

My aspire 8920g restarting with power is on. In the mode safe works ok.

that common in 2008 models. try to update bios. https://www.acer.com/ac/es/ES/content/su

The answer to this Reboot problem is the Capacitor located right under the CPU. Setting the CPU to use only a single core cpnfirms this is correct. There is a repair video on youtube that shows how to do this. The Original capacitor (Single Unit) is peeled off the board and replaced with 4 x 330uf - 2.5v Tantalum capacitors in its place. It takes patience and care to complete, but is NOT too hard for most enthusiasts. Whats needed: 2R5TPE330M9 330E 330 330UF 2.5V D SMD tantalum capacitors
