A few days back my laptop started to crash due to overheating within an hour of usage.
Later it started crashing after few minutes.
Now the situation is such that i can't turn it on.
When i press the power button light indicator shows up, cd rom starts but not the display and then it automatically turns off.
Need urgent help and don't wanna loose my data.
Also a month back i changed my windows from 7 to windows 8 which was working fine.
