Please Help acer , aspire 5920g

I have an acer aspire 5920g laptop that has recently stopped working , when I power on the computer the fan goes on and the power on light also goes on and two other lights flash once but nothing comes up on the screen and the computer never starts the boot sequence....the fan then goes off but the power light stays on , I already put new thermal compound on the processor and graphics card...I tried removing the ram modules , the wifi card and the hard drive ect. nothing seems to work , any ideas on how to fix this?

 

Does the screen show black/white or does it stay completly off?

 

the screen stays off...

 

You might have a fauly GPU. Please try the following to confirm that the fault is in the GPU and not elsewhere:
1- Remove the CMOS battery for about a minute and then and replace it. Test laptop if doesn't boot do 2
2- Replace the RAM and see if it works

If your GPU is faulty for sure you can try http://www.youtube.com/watch?v=SCxc0bxk_1U&feature=related

Check also this: http://www.mxm-upgrade.com/5920G.html. If you GPU is an nVidia one try to replace it with an ATI one. ATI's GPU run cooler and they are less error prone

 

tm 11 I think student2009 means does the screen display ANY kind of activity (even the backlight turning on) or does it stay the SAME as when the pc is off and unplugged?

Watch for any kind of backlight being enabled etc.

When the screen is on and is displaying only black it is vastly different to just being off since the backlight is now on.

I think people want to know if possibly you monitor is not displaying the image.
It may be the case your computer is fine but the monitor wont display.

You say it starts up the fan comes on and the two other lights flash, you could simply mean the hdd light and numlock or something like that, and then it boots to windows, and fan turns of becasue its not needed becasue windows is just idling in the welcome screen. Completely normal behavour.

You need to describe your problem more accurately.

Did it wreck before you opened it up and started playing around with components? Or did it werck and THEN you opened it up to see if you can fix it?

People might be able to help you but you need to give more details. In the end though I think you will have to take it to a local laptop repair store for them to have alook at it. Graphics card sounds like a likely scenario, but since you are opening up the laptop anyway, check that lcd cable!

the montior could simply be no functioning.

Have a look at this http://www.youtube.com/watch?v=WwbrL7HNXjc

If you had a fresh unopened laptop before the problem, you should not have opened it up and started chaning thermal paste, this is the LEAST likley thing that would solve your problem. Next to throwing bread crumbs at birds. EIther gfx or screen for sure., assuming you have not flashed recenlty or mucked aound with bios/cmos, batery etc.

I wondered if this was caused by something to do with a known fault of going into hibernation state, with Windows Vista. I have removed all hibernation options.

 

Thanks for the replies , after trying everything , it ended up being the mxm graphics card , I replaced the card and now the pc works fine!
