Please don't post the same question more than once. I have deleted your other post.

I have a Acer Aspıre 5738z laptop that has been converted to wındows 7 professıonal Turkısh edıtıon

At the last count I have 4 Dell C400s. They have a particular video issue, but it can be worked around. The distro that worked out of the box is: Crunchbang - http://crunchbang.org/. The Waldorf (Debian Testing/Wheezy) version. If you don't like Openbox you can: sudo apt-get install xcfe4*

I have always maxed out the memory of my Dells to 1Gb. If you can, increase the memory.

Welcome to linux.com!

How are you trying to connect? Ethernet? Wi-fi? Something else?

Most of the stuff mentioned as supported by Wine are games. You could look at e.g. WineHQ - http://appdb.winehq.org/

There can be "layers" over Wine, but Wine is at the bottom e.g. PlayOnLinux http://www.playonlinux.com/en/ to Commercial offerings like Crossover http://www.codeweavers.com/products/

Redhat is a Commercial Linux. You have to pay for support. There are free versions of Redhat e.g. Centos - http://www.centos.org/

I wonder how Windows 8 is messed up. A virus? Just borked?

Dual booting will give you a chance to try out your various hardware works under Linux.

1) Don't throw away Windows! Investigate downgrading to Windows 7. You can try Linux without touching your hard drive by:
1. Live CDs / DVDs
2. Live USB with persistence
3. Puppy Linux
4. WUBI (on its way out...)
5. Side by Side Installation (known as Dual Booting)
6. Virtualisation
7. Putting on an external Hard Drive

(There are hundreds of LiveCDs to try. Look at http://livecdlist.com/operating-system/linux )

2) There is an old adage: Linux is not Windows and Windows is not Linux. MANY of your Windows programs will probably not run (well) under Linux. It is a completely different OS.

Some Windows programs will run under Linux using the app called Wine. But not all.

Linux has it's own apps. Some are familiar like Firefox or Google Chrome. but others are different.

So, if you keep some vestige of Windows you can use that.

3) In Ubuntu 11.04 just means it was released in 20011 April (Fourth Month). They usually release in April (04)and October (10). Linux Mint is possibly easier than Ubuntu. It is based on Ubuntu but has the extras already added. Zorin Linux is a good choice for Windows transitioners. (Some people don't like the way Ubuntu is going with its own interface)

As I say - do not throw away Windows!
