Well I've tried a few things and I'm a bit lost currently I have a Acer Aspire 5742Z

Specs :
Intel® Pentium® processor P6100/P6200 (3 MB L3 cache, 2/2.13 GHz, DDR3 1066 MHz, 35 W), supporting Intel® 64 architecture, Intel® Smart Cache Mobile Intel® HM55 Express Chipset

Intel® HD Graphics with 128 MB of dedicated system memory, supporting Microsoft® DirectX® 10 Dual independent display support
16.7 million colors

and I don't know which kind of version to get if I should get a recent type of distro or an older one if anyone has any advice it would be greatly appreciated.
