Computer Crash

[misto]

When I use BBC iplayer or similar either my internet connection ceases or computer reboots. I have windows XP installed.
Never had this problem before.

Have cleaned fans etc but still the same.

This happens with ie8 and mozilla firefox.

Many thanks

it could still be an over heating problem..

run it and it will tell you what the CPU temps are, then run iPlayer and keep an eye on the temps, if they start climbing just before the computer resets then it is an overheating problem.
