    i have an Acer extensa 2510 serial is NXEEXEA00141910DE93400 SNID: 41906909734. I have checked both these numbers and I keep getting a error on Acers warranty check saying it can't find it in the database,but that's not my problem.


    when I try to switch it on, the laptop screen is blank and the backlight flashes on and of repeatedly in less than 1 sec intervals (like a car's indicators). I have tried a hard reset, without battery start, reseating the ram and any other component and cable on the laptop (so yes I have striped it, I work in a pc shop we do repairs) but nothing worked.


    so I switched it on and listened to the HDD to hear if its reading or just spinning and I noticed that it sounded like it was in synch with the screen. my thoughts on this is that the motherboard it busted.
