My laptop is Wipro brand. I have been using it for last 2.5 years. Since a couple of months I am facing a problem of being hanged up. Anytime the screen gets sparked and colors of the screen starts shriving as if it is being shaken up. It becomes like many stars are twinkling, and color becomes many in numbers, all the data on screen becomes the bad mixture of colors and look too bad as well. Mostly it occurs while watching Videos Mostly it occurs while net is on It can occur any time. Even, it occurs at the time of installing windows The laptop's rare becomes too hot. What I thought it is becoz of Virus, so I bought an anti virus, formatted the laptop in full, left no file on disk, installed AntiVirus. but it is still gets hanged. Interestingly enough, it also gets hanged while formatting, or installing windows. My Solution: Thought it might be becoz of heat, so put my laptop in Fridge for a while and then starts, it goes for several hours without hang. Finally, when it hangs up, some time, it does not start easily, unless I wait or put in fridge, When I start it, the indicator of the power appears, and then goes switched off. If it is on batry, it gets off, if it is on power, the laptop gets on, and off, it can not go a head to xp widows. I took and take two solutions, first i formatted it totally, 2) whenever it does not start after being hanged up, I just put in fridge, and becomes normal. Pl get it repaired, if necessary, or give me advise to repair it by self. Thanks
