回複：誰見過這個？thinkpadT61+win7突然s在這個screen,內存還是顯卡？（可以boot safe mode）

not 顯卡, more likely  the Operating System is corrupted. A Window 7 on a T61 is strange.

You can either restore the system to a previous date or reset the system to the factory setting.

The most important thing is to back up your data first.
