[freeze on startup] Acer Aspire 8930G

Hello,

I have a 2y old Acer Aspire 8930G. I wanted to use it this morning, and it started up properly. Then, i went to get something, can't remember what, when i came back the laptop was shut down. Maybe an update or something i figgered. Restart, 5 minutes later it shut down again, but as if the powercable was unplugged rapidly. No warning, no "windows is closing", nothing. Just black from one second to the other.
Restart, 3 minutes later, same thing. Restart, 10 seconds later, same thing.

I went searching on the internet and came to heating problem. So, unplugged every power source, opened him up, and cleaned the fan completely. All the little openings to the heatpipes were blocked with dust, so cleaned the heck out of them, put everything back together and tried an other restart praying to whatever God felt like listening. 10 seconds later, black screen.

Another option was to reset my BIOS, by unplugging the battery, or by "setting it to defaults" in the BIOS menu. Option one, with the battery, is quite tricky because the little part of the laptop i can get open easily, contains the fan, a heatpipe, RAM memory, WIFI and a harddisk. No battery in sight.
So i tried the second one. Opened the BIOS screen on startup, but before i got to de "set to default", the laptop shut down.

So, i'm in a bit of a pickle here.
This being said, i hope you guys know enough to help me.

Maybe some specs, if needed :

- intel Core 2 duo processor T6400
- Nvidia Gforce 9600M GT Turbocache (up to 2303 MB)
- 4 GB DDR3
- 320 GB HDD

Hope you can help me and if not, well, thank you anyway!

 

hi and welcome to nbr
hopefully you havnt done any serious damage but its trial and error until we find out what it could be.
always best to clean laptops out every few months so you will know in future.
lets see if you can get and load into safe mode first. reboot and keep pressing F8 on startup (unless its a different F key for acer).

there has been a few windows updates over the last couple of day and it could be a faulty one but just a guess.

any idea what sort of temperature your lappy is running at. you can find free software in my sig below.

hopefully someone else will have some better ideas on what it could be but lets try safemode first.

 

Damage by doing what? I only removed the dust in and around the fan. But yes, let's hope it's not damaged too bad.

I booted into safe mode before, and it took a bit longer for the laptop to shut down, but still..

Thank you for your comment

 

letting the dust build up too much as after long periods of time this can cause damage by overheating and lower the life of the hardware.

 

Hope it didn't do too much damage then..

 

Your next step is to remove the cpu heatsink, clean it off, and reapply heat compound, reconnect the heatsink and cross your fingers again

 

Thank you for your comment, but i'm gonna need a little bit more guidance.. I really don't know what the CPU looks like.

 

Capacitors keep the steady stream of DC voltage from your power supply to prevent components from getting too much or too little juice. It can also store an electronic charge to be discharged at a later time. A bad capacitor might indicate an intermittent issue with power surging and thus why your laptop shuts off in a few minutes after being powered on.

Normally I wouldn't suggest a bad capacitor is the problem on a 2 year old laptop, but keep in mind laptops can get very hot and if you constantly are picking them up and dropping them it can cause the thin wire connecting the capacitor on the board to snap and thus will cause intermittent power issues (OFF ON OFF ON...etc). Worth a shot?
