ACER 4750G Crisis Mode

Dear All,

I wanted to install windows 10, it came up with some problems during the install and it rebooted. surprisingly now i have my bios damagaed. the bios freezes in the very beginning (there is a blue bar on right side of my screen in bios screen which goes till 80% and then freezes).

So i thought of reinstalling the bios. i have tried this so far

1- got a 8G Transcend flash drive
2-used wincrisis.1.0.0.4 to format it and copied the .wph file and .rom file which i downloaded from acer website to it(renamed them to BIOS)
3- removed AC and battrey and HDD. held Fn+Esc and then pushed power.

the system boots up to a completely blank screen, no sign of movement anywhere (Fan is constanly on low and no extra blinking anywhere)

So my question is first :

can it be the hot keys? if i dont press Fn+ Esc it would be in the freez mode, so i see phoenix bios and then it stops at 80%, if i press them it will go to a blank scree.

am i doing something wrong? what should i change in my setup?

Thank you so much in advance

 

There is no such thing as reinstalling the BIOS - what you are trying to do makes no sense.
One of two things have happened - either some settings got corrupted somehow (you should enter BIOS setup and revert it to factory settings) or there is an issue with your hardware that prevents BIOS from passing POST - RAM, HDD or something else may be failing (enter BIOS setup and see if everything checks out - if HDD is visible, the amount of RAM is correct etc).

After you've dome this BIOS recovery procedure you get to black screen - does it mean you now pass the BIOS POST or is it that not you don't even get there?

 

Thanks for the reply. Well there is! as far as i know (may be i should rephrase, lets say re programming the bios chip) . and my bios is corrupted so i cannot get in to the bios part to change anything and it simply freezes.

and no there is no I/O issue as far as i can check since i removed all the drives(SSD, DVD ROM) and also removed one of the RAM s just in case!


sorry the pic is upside down

 

Well since BIOS itself cannot be corrupted any other way than by a flashing went wrong, it has to be either some hardware of the settings. You could remove the CMOS battery to revert BIOS to factory settings (it takes a while though - few minutes is usually not enough).

I remember I had an issue exactly like that and it was some piece of hardware but I can't remember what it was.
Did you test RAM sticks one by one in both slots?

 

I have the exact same issue (posted in Acer Aspire 5560 thread) under the same circumstance with a 5560. Wonder how many laptops Win 10 UG is going to brick.

Removing CMOS battery for 1+ hr has not helped. No CMOS-clearing jumpers apparent.

 

Funny but I just experienced the same issue. Tried to upgrade to win 10 unsuccessfully and suddenly just like your problem stuck on splash screen with loading at around 75%.

Were you able to solve the problem?

 

I'm stumped by this. It's looking less and less like a coincidence...
