Appreciate all the help. I'm going to try the fat32usb flash method.
I've found the BIOS software required for my laptop model (4752g) but I'm not sure where to go from here. I've got a usb in fat32 ready to go, but the folder contains many files. Do I just click and drag the entire folder on to the usb?
Here's the zip file, if someone wouldn't mind having a look for me http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.24_A_A.zip?acerid=634921025155312677&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE%204752G&OS=ALL&LC=en&BC=ACER&SC=PA_6#_ga=1.81120210.478877701.1456863697
thanks.
