DELL Studio 1558 randomly turning off when installing windows 7
I have a DELL Studio 1558 (BIOS version A08) and i want to install windows 7 on disk C without formating other partitions. The problem is, that the notebook randomly shutting down and i can't install system completly. Sometimes it's happening when it's unpacking system files, sometimes when it's almost complete when finishing installation. Have somebody have any ideas what it's wrong?
