The ongoing saga of a progressively dying machine... Good as Gold for 3 years, then when I start ordering components for a new build, it gets the huff and starts crashing/rebooting. Trace to RAM errors, Corsair are BRILLIANT and refund my original cost (ex VAT) but as equivalent RAM is now less than half the price, this is fantastic.
Get replacement RAM (Corsair of course) and the PSU dies.
Get replacement PSU and on re-assembly get long beep on POST possibly followed by short beep(s). Graphics Card? RAM? Remove both, on powerup series of long beeps.....
Replace components. On power up no beeps. Fans all spinning, all voltages OK. Clear CMOS etc....
No POST beeps.
Is mobo dead?
