Acer ASPIRE 7750g

[Death2allz10]

I have had this Acre ASPIRE 7750g for 3 years and i turned it off one day and it would never turn back on, when i hit the power button the lights turn on, the fans spin, and hard drive starts up but then the fan stops and the system shuts down, it wont even reach the BIOS and if you leave it alone for about 1 month and plug the power in there is a 50% chance it will turn on and boot into windows normally but when you shut it off it will do it all over again. I have changed the battery, and charger, along with RAM and Hard drive and it still never works... Can some one help me please?

it is a motherboard issue pointing to a possible bad capacitor.

i have looked and everything seems fine

because they look good doesn't mean they are good.

True ... but is there another possible idea like the bios?

because it will work 50% of the time if left off for a month or so means hardware issue & you replaced some components but still have the issue. remove the main battery, disconnect the power adapter from laptop, hold the power button down for 20 seconds, re-insert the battery, reconnect the power adapter & turn on the laptop.

Still doesnt work... so how do i identify and replace the capacitor or do i need a new mother board?

check for a can shaped capacitor that is domed when it is not supposed to be.
