Computer problems - again!

Sorry, but I have not been posting recently due to computer problems.

A blue screen appeared on the computer telling me I had a hard disk error. In fact it appears that the problem was the motherboard with its connection to the graphics card. It appears to be sorted now, after a week, but they had to re-format the computer. Not only is it working slower now, but I had to re-configure my internet connection and I fear I have not done it properly.
First of all it did not let me open ANY blogspot.com addresses and now it does not open the majority of my web pages, and the connection speed is SLOOOOOOOOOOOOOOOOOW.

I will take it back tomorrow to try and sort the connection problem.

Sorry, but I hope to get back posting this week ....sometime.
