Computer wont start...

[GenerationYscorpio]

The computer I own cannot even be turned on at times, and if it was turned on it was only for a brief 1 sec. before the power was off again. I have unplugged the power and plug it back and still the same would happen. But sometimes after couple of days of trying or rest it would suddenly behave normal and actually turned on and post into window and everything is fine. I didnt shut down the computer improperly, but lately it happens very frequently that computer just refuse to be turned on. I am using
Asus A7V133a kt133a board
I do O/C my cpu from 800 to 950 but with special fan to cool it. Computer was never freeze due to O/C
Can anyone help a poor fellow here....

Not sure what the problem might be, but first try less aggressive settings in the BIOS. Drop the overclocking for now, reset any memory settings, etc ... See if the system becomes stable again. If so, then just one by one enable the options.

Use a multimeter and check the voltage on your power outlet. I saw once a Compaq PC that didn't start at all because voltage was 210V instead of standard 220V. Maybe use a more powerful power source? One PC I have home does not start when temperature is low (<15 Celsius) unless I let him on power for some time (1 minut at 10Celsius, by example)
