Acer Aspire 4935G Random Shutdowns, Not Charging when turned on

I don't how can i describe this problem detailed enough, But my acer aspire 4935G has been turning off randomly. this laptop has been with me for about 5years now and i suspect that because of the 'age', problems will occur.

I still hope that you guys can help me repair this on my own.

 

Windows vista, core2duo, 3gb RAM, 512mb video

 

Here are the problems (mainly about shutting off randomly)

 

-i will be using my laptop for the whole night and while using, with no heavy applications running, it will just shut off.

 

-the processor fan is running. (i shared this info because i suspect that its due to overheating.) but will still shut off.

 

-i already dismantled my laptop just to clean the fan. I removed the dirt. trust me, i really cleaned the fan and where the air is coming out. clean. still shutting off randomly.

 

-i tried putting a desktop fan under the laptop, not just a usb laptop cooler, but really an electric fan to remove overheating, But still shuts off.

 

-now here's the weird part, i play NBA 2k13, which we know is a very heavy game in terms of processing and video, and RAM, etc,. If i play NBA 2k13, it doesnt shut off! Ever! but if i do an alt+tab, to go to my desktop, after a few mins, it will shut off. weird, thinking that shutting off will mostly occur while playing games. But no, it doesnt shut off while playing NBA 2k13. (this is the only PC game i play)

 

-if i go to ctrl panel>power options> "Acer ePower Management", and if i adjust my CPU Speed to "High" and "Maximum", laptop will shut off in few seconds. So right now, my laptop is always running in "Low".

 

 

OTHER MAJOR PROBLEMS

- for example ill be using my laptop for the whole night, in the morning, if i plug in the laptop, its charging, BUT if i pressed the ON Button, the charging STOPS. so imagine, if i dont have a battery inserted in the laptop, it WONT TURN ON, because its not charging.

 

-now if i put the battery, and i turn on the laptop, it will continue to boot, BUT for as many as 10 tries or more, it wont reach my desktop because the laptop keeps shutting off. AND ITS STILL NOT CHARGING. Hope you guys can imagine.

 

-now my battery is like dead. it doesnt last for an hour. i think this is a common problem for 5year old laptop batteries. so imagine the problem if my laptop wont charge even with the battery connected.  i cant turn on my laptop. i just wish that the battery could hold enough power to complete the boot to windows.

 

-charging of the laptop or electricity flow will resume in the laptop, after a few mins, only if i make it to windows. I don’t know what triggers the charging. But my laptop will just Start charging RANDOMLY.
So this is like the best condition of my laptop, WHEN ITS CHARGING and NO SHUTTING OFF Occurs.

 

-everything just starts randomly in my laptop, SHUTDOWNS AND CHARGING. and I cant really find what triggers the SHUTDOWNS and THE CHARGING.

 

-if i remove the charger, laptop will turn off. battery cant hold the power.

 

 

so those are the problems. I rEALLY HOPE THAT SOMEONE READ this. and Help me repair this on my own.

Im not afraid to dismantle my laptop.

 

what could be the problem? is it the battery? the fan? the charger?

im planning to reformat my laptop, factory defaults or setting. install windows7. but will this help? is this a software problem?

Please help. I know this is still a good laptop.

 

P.S. While making this post, my laptop shut down TWICE! I have to save this to a word file. Pls Help.
