I have an HP Pavilion laptop with A6-3400M APU with Radeon HD graphics Quad Core 1.40 GHz. Hope I got that right :-) Anyway I read something about some AMD not being compatible with Windows 10. I'm thinking about upgrading from Windows 7 to Windows 10 but have read there may be issues. Can anyone shed any light on this? I am a proficient PC user but not too techie. Any advice would be appreciated. TIA. This is a 64 bit machine.
