Im repairing a laptop for someone, but it has me stumpted.
Its an old Acer Aspire 7520.
Its running witndows 7.
When I switch it on, the laptop goes onto the Acer splash screen at first screen, then it goes black, with a continuous flashing dash, it then just hangs there. I cannot Ctrl + Alt + Del, I can only press and hold the power button.
The hard drive seems fine, it shows up in the bios fine, and I plugged it into my machine and copied their data off and had no issues.
The DVD drive is faulty I believe, I cannot open the drive when I've turned the power on, the light continually flashes / blinks, throughout the whole time the screen is black also. The hard drive activity light blinks continually also.
I plugged in a USB dvd drive and tried to boot off that, it spins up when I turn the laptop on, but then does nothing, doesn't attempt to boot off it even though I set it to in the Bios.
I don't know what to do, I cannot boot off the hard drive, or boot off the DVD drive, internal or external.
I was thinking maybe faulty ram, but I have no way to test, I dont have any spare and I cant boot off my memory testing application.
The dvd drive doesn't show up in the bios either.
The ram shows up fine in the bios also.
I don't know what else to do.
The bios can see the hard drive but it doesn't even make an attempt to boot from it, and the hard drive is working fine.
