I reinstalled Vista again this time using Home Basic and on another HDD but exact same browser and internet problems. In the Device Manager, looking at Network Adapters there is only :Intel Pro/100 VE Network Connection for which there isn't a yellow exclamation mark, only 2 entries under Other Devices are showing the yellow exclamation marks and those are PCI Simple Communications Controller and Unknown Device?Anything I can try here to solve this problem please?
I am sorry you are having problems with your system but let me help you.
Based on the motherboard specifications I am afraid that the latest Operating System it can support is Windows XP and this may be the reason why you are having problems with the some components due to lack of drivers for Vista, Win 7, Win 8/8.1.
You can check the Operating System compatibility information at the following link:
