8935G No bios boot, only black screen.?

8935g suddenly died??
Hi there, i am new i this forum and am online by phone at the moment, a little confusing så sorry if i am posting wrong.
I really need help with my newly bought Aspire 8935GBought it the other day, secondhand and at a nice price. Former owner told me that if playing for long it would shut down and just needed to be cleaned as the heat caused the problem. Well when i got home and bootet up i discovered that only 1 ram stick was in it at 1gb and the blueray was removed and replaced. He tricked me a little i think but it was cheap :sI then decided to install 4gb of ram in it and a t9300 cpu from p7550 (a downgrade sort of i know.) Suddenly it wouldnt start up with screen. Only black screen, all lights on as usual, fan spins up and then back down, hdd spinup, cd spinup but no screen and nothing more, just black.
Here is what ive tried so far:Total disassembly, cleaning dust, reapplying paste, 3 different cpu's, an nvidia gt130m, 2 other sets of ram, another hdd, external monitor, flashlight on screen, about everything mentioned in other threads but nothing, just an empty black boot.. any advice, any knowledge, would rlly like to have it working again so i cqn start upgrading like hell.

Best regards
From Denmark.

 

Does it work with 1GB RAM stick it came with?

 

Hi, thanks for reply.
No it does not work, tried it in both slots and still no boot screen.

 

So it doesn't work anymore in the configuration you got it in- am I correct?

 

Yes, you are correct.

 

Remove the battery on the mainboard and it will hopefully start again, worked for me.

 

Install CPU and RAM with which your laptop came. Remove battery, remove AC plug from laptop, push the power button and keep it pushed for 10-20 sec. Re-plug graphics card. Than plug AC adapter to laptop and try to boot again. Whith which CPU it came?

 

Nedriver, did you try the steps the guys posted to resolve your issues? If so did they work as i am having the same trouble and would like to know if they work before i start stripping the my laptop down?

 

I don`t think that he will respond to your message - lot of time has past since his last message.
