Almost out of the blue my computer went into a fit of blue screening and now my computer wont turn on (A majority of the crashes were Machine_Check_Exception & DPC_Watchdog_Violation). Now when I press the chassis power button the leds turn on, the fans spin & i can hear the hard drive moving. Ive tested the hard drive, video card and ram thinking those might be the problem to no avail. I uninstalled the cpu and cleaned it to reapply thermal paste and that wasnt it either. I unplugged all the power connectors several times to no success either. Ive also reset the CMOS and it still didnt display or post.

Also my motherboard gives me post codes with a little LED on the board
(It gives me post codes 19 00 4C 31 34 3A 32 40 and then stops on 60)
This is all the possible codes it can give you:

02,07 - Power on CPU Initialization
03,08 - Power on North Bridge Initialization
04,09 - Power on South Bridge Initialization
0B - Power on Cache Initialization
11~14,32~36,56~5A - Early CPU Initialization
15~18,37~3A - Early North Bridge Initialization
19~1C,3B~3E - Early South Bridge Initialization
1D~2F,31,3F~4E,50~55 - Early Memory Initialization
63~67,D0 - Late CPU Initialization
69~6F,D1 - Late North Bridge Initialization
70~77,D2 - Late South Bridge Initialization
92~96,B5,D4 - PCI bus Initialization
97,98,99,B2,D5~D7 - Console Output/Input devices/Console initialization and Load Option ROM (VGA, RAID, parallel ports, serial ports……)
9A~A7,B4 - Onboard devices Initialize and Detect (USB/ SATA/SCSI……)
A8,A9,AB - Start of Setup. BIOS setup if needed/ requested.
AD/AE - Ready To Boot event/Legacy Boot event
CPU temperature - Fully boot

Its basically taking everything out of the case (to prevent unwanted grounding) and testing the vital components, adding one at a time until you find the culprit thats giving errors. Also do you have an internal speaker to check beep codes? or is it only led codes on this mobo?

Oh i figured as much, no mobo speaker from what I know. I never hear any beeps or anything so I would assume it relies on the led counter to display errors
