Bluescreen on windows 7 on startup

Hi all,
i'm using the French version on windows 7 Home premium, and since last Tuesday, i have several blue screens on start up. I don't have accurate knowledge on computers, so i hope u can help me to find the source of this problem.
I'm using an HP dv-6, AMD Athlon dual-core m300 2Ghz with 4Go RAM.
there is some of the analysis on reboot after blue screens:

thanks for taking time to read this .
 
When we see so many different error codes that is a strong signal that the issue might be corrupted memory.


run memtest on your RAM.

See the link below and follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes; the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

If you have errors you have corrupted memory and it needs to be replaced.

Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

* Get back to us with the results.
 
Thanks for your help Route44.
I'm using anotehr computer to reply, bluescreens don't even let me try to run Memtest,a dn they are random (sometimes on startup, sometimes after a while).
My computer is still under warranty , so i think i'll send it back to repair, hope they will change RAM's if they are corrupted :)
 
Here is the thing about memtest. It engages seconds after you boot-up. You don't have to load any screen for it to work. Place the CD in the drive, reboot and it will take over.
