I've an Acer Aspire T, which had Windows 8 preloaded. I wanted Windows 7, so I purchased an OEM disc from Microsoft. Running the disk failed multip-le times, until I enabled CSM in the BIOS. The install disc ran this time, but it loaded with very strange graphics: blotchy parts, a highly-pixellated display, and unclear screen dimensions. I continued through with the installation, and everything worked. Upon the final reboot, the system maintained those strange graphics, and even failed to recognize ethernet cables. I tried reinstalling chipset drivers, ethernet port drivers (so I could update everything else that way), but no dice. I am completely confused as to what to do.
