I am using Windows Vista Home Premium 64 bit in my HCL Beanstalk machine with 1 GB RAM. The processor is Core 2 Duo. But my system has become too slow to work. "Not Responding" messages have become frequent. It gets stuck whenever i try to open any application. It shows up even if i open My Computer. I have formatted my machine 3 times but the problem still exists. I tried to install windows xp but the audio driver was not working so i had to reinstall Windows Vista. Also want to know if system problem can affect broadband connection as the connection gets lost many times in a day.
One of the best and cheapest ways to improve performance on a PC is to increase the RAM. I would try installing 2 GB of RAM and see if that helps at all. If not, I would suggest backing up your data as soon as you can and get a new hard drive. As Ramhound said, it is also very likely your HDD is failing. Also, you could try running Disk Defragmentor which comes with Windows systems. This will rearrange the data on the HDD closer together to improve performance.
Windows Vista is very hardware hungry and required an unreasonable amount of RAM and processing power to run efficiently. Now with more modern computers that wouldnt be a problem but your machine only has 1gb of RAM and im sure Vista uses about 660mb of that, I could imagine you dont have the most powerful processor in there either. This doesnt leave much left over to run other applications, or do much at all really.
I think you should update some of your machine hardware like the RAM and the processor or better yet build or purchase a newer more powerful machine which comes with windows 7.
Times are hard for everyone right now though so if buying one isnt an option then go back to re-installing XP, try and find the correct sound drivers online as well as the drivers for all your other hardware and you should be good to go and much better off than with Vista.
Microsoft are aware Vista was a terrible operating system hense its relatively short lifespan compared to windows XP
