Hi all,
This may be a very stupid question, but I thought I'd ask. I've had Virgin MEdia Broadband for about 3 years now. I'm on the 4mb package which I think has been uplifted. I purchased a new pc in Jan, and only until about a month ago have I experienced good net speeds of around 400kb.
However after about a week on pc probs, I've had to do a master reboot. The net speeds today have gone back down to around 40-60kb which was what they were when I first got the pc.

I was wondering if master rebooting my pc can cause the speeds to revert back to what they were, and are uplifts in speeds lost as a result???

Any advice or help would be great, been a very frustrating week with pc's, I hate Vista!!

Thanks for your time
