Hey all, Reformatted a colleague's PC (Mesh Premier Pro Desktop with AMD Athlon 64 2.0ghz processor, 1GB DDR RAM, Asus motherboard (cant remember serial as am at work atm)) which was a few years old. I have put a retail version of Windows 7 Ultimate on without a hitch. Looking in device manager, there are no yellow exclamation warnings which indicates to me that all drivers are good and installed correctly. The problem is that every time the PC restarts, it installs drivers for PCI Bridge, audio drivers and a few others. They all install correctly and the PC goes about its business but it is annoying that the PC 'forgets' it has drivers installed already. Anyone please shed any light on this peculiar issue? I am thinking it could be chipset drivers or the BIOS needs updating or maybe a new CMOS battery required? I would very much appreciate some other views or ideas. I hope to have a crack at it again tonight (UK time) and will hopefully be able to post a solution! Many thanks for reading.
