vista not responding

[onozote]

i am using a toshiba notebook, my problem is after about 5 minutes of logging on it comes up not responding and freezes, i then have to turn off and start again which is frustrating when your on a forum, this can happen more than 20 times a day, i have a wireless router which worked on and off ,so i connected a usb lead from the router to the laptop, any ideas ?

how hot is this laptop getting...

try resting the laptop on some videos boxes.on a table...so you have at least an inch space under the laptop.

poor air circulating will shut a laptop off. make sure the video boxes DO NOT block the cpu fan.

.....

have you ran anti virus scans etc.

try this one http://www.trendmicro.com.

post back once you have tried these.
