Cannot turn on system or launch repair mode
I am writing to ask you about a problem that I have with Acer Aspire E5-571G-52VR. This laptop has Intel Core i5-4210U, GeForce 840M 2GB and 4GB of RAM and is not mine. A few weeks ago it has been cleaned and I installed Windows 7 64bit there. There hasn't been any problem before yesterday. When owners were using this computer, it suddenly turned down the system itself. When they were trying to turn on this computer, launching screen was shown but after that, there was the blue screen for a second and laptop rebooted system itself.
I was trying to reboot the system using repair mode and also trying to install a new system with original CD. It is working for a short time and then everything crashes.
What could it be? Is it hardware or software problem? How to solve this?
