On my SE7320EP2, everytime I boot up it greets me with the "Error (51A2): System cover has probably been opened". The chassis intrusion switch has been totally removed and we have tried to put a jumper on the connection but we still get the error. We have cleared the event logs in the BIOS and it still comes up.
Any suggestions besides changing out the motherboard?

the media player's firmware which contains bootable files is seems corrupted. probable cause is virus or electrical failure of firmware. you can scan the player by computer which has latest updated anti-virus. if that not work try to format it. you can get the firmware if it is available from the manufectures web site, try to reload it.
If you have installed a new hardware or software, it may be conflicting with the installed program there by causing your system to dump it time the conflict occurs. You have to boot the system to safe mode and uninstall the new software or remove the new hardware and restart the system. Your system is supposed the boot okay.
What this means is there currently is not enough hard drive on the unit to boot up windows. If there's not enough free space on your hard drive, Windows won't open. Try accessing through Safe Mode and see if you can create the necessary room. Boot the system, start tapping F8, when the menu appears, select Safe Mode and press enter.
