Replacement Motherboard 5552G-7464

Hi, I tried to boot my laptop today only to get a black screen, no bios/post, nothing. Power lights come on, fans spin, but thats it.

I have tested it down to the point where I am pretty sure its a GPU/Motherboard issue. It has always run pretty **bleep** hot so I'm going to attempt a reflow on the GPU tomorrow, hopefully that will fix it for the time being.

If not I will be needing to replace the motherboard. My question is: How do I figure out which motherboard I'm going to need? Can't find any obvious part number for it and I was quite surprised to find I can't even contact Acer to find out, even via email. As much as I have liked their laptops over the years I find having to pay to contact customer service to be really poor customer relations. Unimpressed!

Anyway, I hope someone on here will be able to point me in the right direction. Thanks in advance.

Ryan.

Normally on your mainboard ram sockets is a sticker which will start with MB

Take the first 10 digits, for example MBEFN01002 and put in some dots to make it a part number : MB.EFN01.002

Google the mainboard part number Smiley Happy

If you have no sticker if you post up the first 10 digits of your computers serial number maybe I can identify the mainboards part number for you.

Thanks for your replys, hopefully it wont come down to replacing the motherboard, fingers crossed.

So this took a strange turn this morning. After leaving it sitting for 12 hours I tried to boot it up and surprise, it went into post. After that it went to a windows update screen, went to updating 100%, then I got a blue screen of death with the error code "worker thread returned at bad irql" then it restarted. After that straight back to black screen of death and can't get it to post again.
