I rather my problem fixed than alleviated but if this really does alleviate it at all, thanks.
Hi,
I understand your situation.
The application not responding is a common problem with Windows Computers and there is no guaranteed solution for this however there are ways to avoid it.
The main cause of the problem is when certain number of programs are running and accessing disc or hard drive at the same time consistently. The best way to avoid this problem is to run less programs at same time, specially the ones which have high disc access.
For example if you surf the web while scanning your PC for both viruses and spyware using another two programs then you will more likely face this problem while loading webpages or watching videos online on YouTube. (because they are too many programs trying to access the hard drive and therefore some programs may become less responsive)
Another way to avoid this, is to make sure that your Hard drive is de-fragmented regularly depending on its usage.
Consider saving your files in a different partition and keep your drive C: clean and avoid installing unwanted programs and de-frag it regularly and keep some free space for it. (keep your files in a external hard drive if possible)
Reduce your start up programs and uninstall any programs that you do not use or rarely use.
Upgrading your hard drive can be another option but it won't guarantee the fix.
Hope above helps!
