Now I tried repairing it through windows vista disc.. but it won't allow me because it doesn't display the operating system, I tried setting as last know configuation, resetting CMOS, fiddling with the BIOS, changing out parts.. none of them work. I can't even get it to reformat..
It's a Acer Aspire M1641 desktop.. did not came with any disc or the person i'm repairing it for never made a backup.
Really need help.. pretty much fed up with this. Thanks.
