I am new here so please bear with me!
I am having a rather strange problem with my (almost) 4 year old dell laptop.
Every time my computer connects to the internet it slows and freezes.
During Saturday morning the system was going into standby mode then froze. I had to manually turn the machine off (by holding down the power button).
Upon restarting the machine it was fine, until i connected to the internet that is.
The machine slowed down considerably and eventually froze, needing me to manually turn it off again. The cursor worked for a while but nothing else would respond (including task manager). It also made a quiet periodic noise, like the hard drive was being accessed.
After this happened a couple of times i realised it occured a few seconds after the system connected to the internet. The computer works as normal if i have no internet connection. I thought maybe my wireless was the cause so tried via ethernet but the same effect occured.
Then I wondered if virus/spyware was affecting the system so did checks with Avast!, Ad-Aware, Spybot and Malwarebytes. All of which came up negative apart from a few cookies, which i cleaned up.
I have tried system restore a few days before the problem occured, to no avail. Now for some reason ALL my restore points have disappeared.
Now I am at a total loss.
Any help would be GREATLY appreciated
P.S I have Windows XP Media Center Edition with SP3
