Hey all, I'm having trouble with my PC. An external HDD was pulled out while the computer was booting up and after that the PC won't start. Three beeps sound, and then the computer instantly freezes. I can't boot from a disk or USB, nor can I flash the BIOS as the computer freezes as soon as it starts and won't respond to any commands (like F6 for Boot Menu for example). There is a horizontal green bar at the top of the screen and it sits there without changing. I opened up the shell and reset the CMOS manually (tried both the switch and removing the battery, both gave the same result) and it gives me one good start, and after that it is fine. I can access my Windows or Linux partitions no problem and everything is completely functional. The only issue is when I want to restart the computer it does it again. Which means I have to open the shell, manually reset the BIOS and start all over again. Argh. Does anyone know a fix? I wanted to flash the BIOS but can't do it as I can't access the boot menu when I restart, nor can I find a way of re-installing it from Windows. My specs are as follows: Processor: Intel Xeon E3 1240 V2 @ 3.40GHz Motherboard: Intel Corporation S1200BTL Bios Version/Date: Intel Corp. S1200BT.86B.02.00.0035.030220120927, 2/03/2012 PS: I am a mega n00b when it comes to this stuff, mainly working things out as I go, so please go easy.
