Xbox 360 E74 and other E-codes: what they mean and what to check
An Xbox 360 showing one red light and an on-screen 'E' code is telling you roughly where the fault is. E74 is the best known and is linked to the GPU and eDRAM link (and, according to many repairers, the HANA/ANA video chip), while E68 and E79 often trace to the hard drive or flash. Read the code, try the cheap checks first, then decide on board work.

Xbox 360 Red Ring of Death (three red lights): causes and real fixes
Three red lights on an early Xbox 360 is a general hardware failure, most often the graphics chip's connections failing after years of heating and cooling. Read the secondary error code first to rule out power and other faults. Towel tricks, oven baking and quick reflows only work for a short time, if at all; a lasting repair means replacing the failed chip or the board.
