Windows 7-Setup hangs after windows is loading files with black screen

I'm new here.I couldnt find any solution for my problem anywhere and i thought i can find it here.

I have Windows 7 Ultimate 32 Bit and im trying to install it for about 6 months.

I installed it once but after one week,os is gone and stuck at classpnp.sys

Here are the steps i followed when trying to install;

Selected Boot Menu > CD/DVD

Seen windows is loading files.

Seen Starting windows but its gone before the 4 colored windows logo comes.

And endless black screen.

I also tried to boot from dvd in safe mode.It hangs at disk.sys

I checked rams.

I have 1 gb x 2 rams.There is blue and brown sockets for rams on my motherboard.

Both of rams connected to blue ones.When i disconnect one of them pc opens but same issue.

When i disconnect one of them and connect it to brown socket pc didnt opened.

Please help.

Hi and welcome

Why is my screen black when I start Windows 7?

Check your ram.
Memory Diagnostics Tool
Memtest86+ - Advanced Memory Diagnostic Tool

Check the hard drive with the manufacturer's diagnostic tools.

HD Diagnostic

I'm working now.When i come to home i will try.

I forgot specs;

(1gbx2) Kingston 400 mhz

eah4670 1 gb

amd athlon 64 2.1 ghz.

Where did you get Win7? Did you burn it yourself? Try burning another DVD using ImgBurn at 4x speed.

Thanks for all.I've burned it myself.at 4x tried 2 or 3 images.
