I hope i'm in the right topic though, as might become apparent, i'm not entirely sure if the issue is hardware or software related.
When i switch my computer on it runs fine for ten minutes and then freezes for around 10-15 minutes. after that it normally returns to how it was but sometimes the internet doesn't work. Whether the internet works or not seems to be completely random to me.
are there tests i can do to find out what is causing the problem? I suspect its a RAM issue personally as i have upgraded to 2 x 4gb sticks in the last year.
The system is around 7 years old. i am at work at the moment but can give more information on it later if necessary.
thanks in advance.
