BSOD after win 7 install

Hi all,

I'm here after trying without success to fix my problem... so i guess this is a call for help

It's taken a long while but i finally decided to ditch vista and upgrade to win 7... reason being i am ok with computers but not born to it... so it always seemed a daunting task ^^

So i formated my hdd, then did a clean disk during the installation, made a new partion and installed win 7... upon completion installed mb drivers - chipset, atk, lan, audio.
Then installed video drivers and set about updating ie, downloading win updates... and setting up the desktop as i like it.

Windows got half way through updates and then BSOD... tried at update again and BSOD... tried to use browser BSOD.
Some times it will BSOD without any interaction from me.

I found these forums and tried to follow advise such as sfc.exe which it would BSOD while performing... eventually i managed to get through 4 consecutive /scannow with always the same out come... found errors can not fix them.

So tried the next step of advice i've seen given on forum and did a win 7 repair with cd, everything seemed fine.. reinstalled drivers it said would be effected.
Then opened up browser BSOD... tried installing updates BSOD... tried sfc.exe BSOD.

Also i've just notced in 'control panel\hardware and sound\devices and printers' it says i have a fax machine and a microsoft xps document writer installed of which i have neither... is this normal?
And windows is not letting me access my external hdd any more... it sees its plugged in as says safe to remove... but cant see it to copy files from.

I guess im stuck and out of ideas ^^

Thanks in advance for your help.

just performed check disk, all clear... will try memtest now.

Thanks for your help, cpu and memory are at standard settings at the moment.

PC is not letting me run memtest Oo, tried with bootable cd and flash disk no joy, yet both work on my laptop.

Trying fresh install of windows... also when setting up hdd during installation is it normal for win to see 3 partitions?
I know it normally sets two, one for installtion and main volume... it is showing a third with 0 space and 0 available space oO.

Thanks in advance

Ok got memtest running and looking at the screen so far its found 288 errors and actually looks like its locked up >.<

forgive the obvious question... so if i buy new memory will my problems be solved?

also the sound drivers were the lastest available from asus website.

Thanks again

I have 2 x2gb sticks, finally finished a full memtest of both sticks in all 4 slots.... it was the 2nd bank of two that was faulty... both sticks are happily running in bank 1 with no BSOD.

Thanks for your help carwiz, and ty memtest... problem solved ^^
