I did a bit of research on folks with same Dell & Foxconn motherboard.
Found three common solutions:
- replace the power supply (hey, this is easy and low cost, maybe $35... if it doesn't work you can just haul the new power supply back to the store... See below, power supplies can and do get "weaker" with age, and at some point don't have enough juice (current) to start up the computer. )
- defective expansion cards (not sure if you have any, but, remove them from the computer and see if LED no longer blinks when you try to start up (but, a "weak" power supply could also cause this. Power supplies are, just like a dead car battery, it "try's" to start the car but can't quit do it....)
- and finally, the motherboard itself...
