Today I installed Arch Linux on my old desktop which used to work just fine with Ubuntu 12.04.
The installation was successful and I installed SLiM session manager and xorg and all dependencies.
After that I installed kde and added the entry to my xinitrc file.
It doesn't matter whether I log in using SLiM or by running startx in tty, the KDE begins to load its welcome screen (if that's what it's called) and then my system crashes. Random lines are displayed on the screen and I have to forcefully reboot using the power button.
I thought it might be my system which couldn't handle a heavy desktop environment and hence tried installing kdebase - the same problem existed.
I also tried cinnamon, but lately I've had a lot of complications with Cinnamon even with the best possible hardware configuration.
What do you think could be wrong? How can I solve this problem. Do you recommend using any other desktop environment? I've been comfortable using cinnamon with Linux mint and KDE with Ubuntu before so anything similar would be great.
The VGA device in use would be:

And the driver that I'm using is:
