Welcome to the Seven Forums, Grouch84.
I suggest that you download an ISO image of W 7 64-bit installation Disk from Official Windows 7 SP1 ISO from Digital River « My Digital Life
. If your OS is not among the ones listed at this site then you shall have to download and run eicfg Removal Utility to make the ISO universal and then burn it to a DVD to make your own W 7 Installer Disk.
You can then clean install it on your Acer Laptop and activate the OS with the current Product Key that is also stuck on a label on your Laptop's base. Keep all your device drivers (particularly the Network Drivers (Ethernet and Wi-Fi)) handy as a few of them may or may not get installed.
After that you shall be able to do everything that you are not able to do now.
