To solve your issue, please follow the instructions given below:

Hello, Thank you for contacting Acer.
Regarding your enquiry,

This is a hardware issue on the computer. As the machine is Out of Warranty, if you want the machine to be repaired, you have to pay for the courier charges and then the repair charges.

There will be a £54.00 charge taken from you before your machine is brought in for repair. You will then be given courier details so that you may arrange collection of your machine for shipment to our repair centre. Once received in the repair centre it will undergo assessment by one of our technicians. They will draw up a written proposal for you containing full details pertaining to your repair. This will be sent to you by post giving you ten days to respond.

Once you have received the proposal you have the option to reject it, which means the £54.00 will cover the engineer and couriers fees, and the machine will be returned to you un-repaired. After ten days, if your proposal is not signed and returned to us by fax or post the repair is defaulted as rejected, your machine is not repaired, and shipped back to you. We can not give estimates of repair costs, under any circumstances, without the machine being diagnosed by an Acer technician.

 

If I was you I'd be trying a replacement hard drive.

With my original AAO A150 I did initially have the same problem with the RAM. Black screen after installing it. I subsequently swapped the stick with a smaller one and it worked, so figured what the hell and put the larger stick back in. For some reason it worked. So don't shy away from your extra RAM just yet.

You may find that a BIOS upgrade could potentially resolve both issues.
