Overheating. Try using canned air and blowing out vents. If you are comfortable with it, take the laptop apart and clean it out. If not, contact a local computer shop that can do it for you. If cleaning doesn't do it, the CPU heatsink will need reseated or the CPU will need replaced.

Overheating usually happens when the fan is not coming , therefore when the computer
overheats.Or the fan is not cooling enough and computer is
overheating.
Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.
If fan comes up but does not cool enough, then replace the fan, it is
not efficient anymore because of a bad bearing or dust. ~Also ensure
that fan is well mounted, if fan has poor contact with CPU surface ,
cooling will be poor.
If fan does not come up, and critical temp is not detected, then the
sensor on motherboard is bad, this is very uncommon. When this happens
the problem is usually related to system or power settiings , rather
than overheating.
If fan does not come up and temp is critical, then fan is faulty, replace it.
There are also more than one fan on many laptops, check that one of the
fans (CPU fan, video fan) is not completely ded, and therefore cause
for the problem.
By using the software below you can also find out if the problem is
really overheating. If temperature results within normal range, then
usually it is not overheating.In that case test systtem and check power
saving settings.
Here is the software to control your fan and temp. sensor state:

If the fan is not running, your computer will definately have a problem very soon. Sometimes, the fan is just clogged up by dust and debris. Head down to a local computer store or one of the box stores and purchase some compressed air dusters.
Dust out the fan and vents as best you can. If the fan still does not spin, your computer will easily overheat and, in all probablilty, shut down on you at random.
If left for too long, this could cause multiple other problems for your computer. I would recommend you look at getting the fan replaced as soon as possible if you cannot get it to work by dusting it out.
Good Luck!

Why don't you try these free programs first. Download the free program called CCleaner; http://www.piriform.com/ccleaner
Run the cleaner than run the registry cleaner. See if you're system stops locking up.
Still no help? Download Defraggler and run it. Lastly on the same site download Speccy and check if there is a heat problem within the system.
If you feel its the MB you can replace it preform a simple google search; http://www.google.com/products?hl=en&q=ASUS+M2V&um=1&ie=UTF-8&ei=L-XtS7CMDYH-8Ablxtj9Cg&sa=X&oi=product_result_group&ct=title&resnum=3&ved=0CDAQrQQwAg
