Tried to delete files on an SD card. Got a non descript error message. Tried to cancel and it hung up. Task manager to end process on explorer. After a min my normal desktop appeared. Got "explorer not responding" when I tried to open a folder. Restarted computer and it took a long time so hard shut down at power switch. On restart it went to dell splash screen for one sec and then the black screen with blinking cursor. Restarting with hitting F2 no change. F12 on restarts just beeps.
Disconnected all peripherals inculding all but one internal hard drive. No Change. Tried Vista disk with no change.
