N200 Windows 7 random dead screens

[yigit]

as i remember under c:\windows\dmp.

press f2 to bios and check bios order your hdd is on that list. if you can't see your hdd on linux, too, probably your hdd is dead. then contact lenovo support line for replacement.

one more thing, you can use one key recover button to perform clean windows installation. let us know if it works.

I solved random dead screen but i cann't solve period stopping windows 7 working

even i reinstalled windows 7 but before installing any software of driver i had the problem. i repeat the scenario of problem:

when I'm working suddenly all the works stops and light of hd become on and ater 1 to 2 minuets , all the things become normal.

probably application or driver issue, possible microsoft services issue. check logs by right clicking my computer > manage > event logs. and post the error id if you have.
