The computer brand name and number does not provide much information, especially considering the same models can be configured differently.
I am assuming you mean the Desktop Acer Aspire M3201.http://us.acer.com/acer/productv.do?LanguageISOCtxParam=en&kcond61e.c2att101=41536&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=450&ctx1.att21k=1&CRC=4219977319
For this desktop in any configuration the answer is no. For GTA4 you would need a computer with a powerful processor, as GTA4 seems to tax the processor more than the graphics card. A Core 2 duo, core 2 quad, Athlon IIx3, athlon IIx4, or a phenom II x3. And you would need a graphics card with 1GB of graphics ram. Preferably something like an ATI radeon 4850/nvidia GTX250 or better.
If you need clarification on anything, let me know.
