Hi, I am using Microsoft Windows Xp Professional on an IBM notebook. Suddenly, It started to crash each time i try to enter windows in normal mode. It shows a blue screen and then restarts immediately: Bad_Pool_Caller Technical information Stop: 0x000000C2 (0x00000007,0x00000CD4,0x00310000,0xE1624FA4) Beginning dump of physical memory physical memory dump complete. When I try to enter windows in safe mode I don't encounter any problem. Additionally, I have no idea about a new driver or application i installed. How can i solve this issue?
