Laptop missing RAM; 1 slot of RAM suddenly not working & overheating.

Hey everybody,

Thanks for viewing this page.
before I send my laptop to Acer for repairs, I would like to consult with you guys, ok so,
it was yesterday when I found out that my laptop is missing 4GB of RAM out of 8GB (4GBx2). So I checked both RAM cards, and switched their places, confirmed both are working, and confirmed that 1 of the 2 slots ain't working no more.

I would like to know is there anything that I could do to fix it?

Here's the second part.
Now currently on 4GB of RAM, with my laptop's specs;

Aspire V3-571G
Intel Core i5-2450M 2.5Hz with Turbo Boost up to 3.1GHz
Nvidia GeForce GT 640M with 2GB dedicated VRAM
4* GB DDR3 memory
750GB HDD
Windows 7 64 bit

Still under the 1yr Acer warranty

...it would be able to manage running high end games right?

Well, now these two days running Counterstrike GO seems to be a problem. When I start playing the game, it's normal at first, but very quickly my laptop somehow overheats quickly and lags.
Also with Battlefield 3 in campaign, with the screen resolution at max, running under 1 minute in the game everything is fine till it lags and overheats so quickly. While playing both games, laptop was set to high performance, with the vents clear of obstruction, with just a page of Firefox running or two.

I have never encountered this overheating and lagging problem before while gaming, and the missing RAM too!

Any help in configuring these issues would be gladly appreciated!
Thanks again,

Regards,

Kelvin

Since you've already swapped out RAM modules and you've determined that one of the RAM slots isn't working, I think the best thing to do is return it to Acer for warranty repairs. One caution, however. Did the computer come with 8GB RAM when you bought it? If not, you may want to install the original RAM so the computer configuration is the same as when it left the factory.

If you do send the computer in to Acer for repair, make sure you tell them about the overheating and lagging issue. I believe it's related to the faulty RAM slot but as long as Acer has the machine, let them do a full diagnostic check to make sure nothing else was affected.

Thanks.
I'm pretty sure RAM upgrade won't affect the warranty, because I have sent this laptop to Acer before.

Just thought about the reason for my laptop overheating is... the fan isn't working, I think!
That might be the reason cos not as much hot air is exiting from the vent, as I remember!

Also, this laptop has also experienced sudden restarts/shutdown a few times when I lift/tilt it at random angles when moving it, since it came back from a HDD replacement from Acer. Possibly not entirely secured internal connection somewhere?

Will have to send my laptop to Acer again! -.-

Just make sure to tell Acer what all the symptoms are. But I wouldn't offer any suggested fixes. For example, it's OK to tell them the machine is overheating, but if you say, "I don't think the fan is working," they might check the fan, find out it's working, and not check anything else. But if you simply leave it as an overheating problem, they'll be forced to check the fan, and any other heat related issues like a short, etc.
