Hi guys,
I just registered here today because I got this weird problem with my computer, but no solution.
I own an Acer Aspire 5742, model no. PEW71. It is running on Windows 7. I included a vid for you to see what the problem is:

So, as you can see, the computer can be turned on, but it doesn't get through the acer screen on to the windows picture, and it automatically reboots and shuts itself down again over and over again. This has happened in the past, but the repairers have reset the operating system and BIOS. They also switched the hard disk for a new one, but this could be because of some other problems I was having (USB channels weren't working). Everything worked fine for a month or so, and then it happened again. I myself am thinking about the motherboard being damaged.
When this happened in the past however, I was still able to turn on my PC sometimes, so I was also able to save my files. Now on the other hand, I can't get the computer on anymore. I really hope you guys have a solution. The most important thing to me is saving the files. After that, I'll take it away for reparation again, where they will probably delete everything again (I can't commicate with the repairers myself, so I can't discuss terms or anything).
Edit: at the end of the vid you can see me turning off the computer by pulling out the adapter. Removing both the adapter and accu is the only way the computer can be turned off. Even shutting it down by pushing the on/off button for 5 seconds will not prevent the auto re-boot.
