Thanks Guys, As said earlier, I tried logmein and it worked like a charm. I could access the computer and its files. I did not need to transfer files, so I havent tried it yet.

The reason to access it was, my brother doesnt know much about computers and he was complaining about the laptop hanging up after a while. I tried to see if he had installed any new programs, ad ons or whatever. Found out that he had done nothing. Its a fresh laptop with like just about10 additional programs installed - firefox, chrome, ccleaner, avg, some wireless router drivers and some ad ons like flash player, media player, real player and those basic ones. It got hanged while i was accessing as well... Its sony vaio bought 11 months ago, and used may be like less than 1000 hours altogether. Any suggestions what could be the problem? My brother said that it hangs up more when it is connected to AC power but it did when on battery as well. I think it is not the overheating problem coz when that happens, the computer shuts down, not hanging.

Also, I do not know if this kind of problem is covered by manufacture warranty,  and if there is sony store in Nepal or not
