black screen with flashing underscore/random bsod

each time my asus n61jq laptop boots i get a black screen with a flashing underscore that disappears after a second or so then windows 7 home premium x64 boots and half of the time i get a random bsod the last one was video.prt
my laptop specs can be found here ASUS N61Jq A1 Specs (Core i7 720QM 1.6 GHz, 16" TFT) - Laptops - CNET Reviews or so i think my laptop is n61jq but at the bottem it of my laptop it says id:A2 but i can't seem to find the specs on internet
note: i have run memtest86+ 12 passes (no problems), chdsk(no problems) , scannow (no problems), i reinstalled pc, run the pervx software ( you never know right)
i checked as many drivers as i could. i flash my bios with succes.
this problem has been bugging me for a few months now i have sent it back and they replaced my harddrive and said it was fixed but well it isn't so i started to search myself and try things but now i really don't know what to do anymore.
i even googled almost everypiece of software on my pc if it could cause a bsod .
i do think the flashing underscores with the black screen have something to do with it
also it's my first time posting a minidump so i don't know if i'm doing it right.
hopefully you can help me because this thing is killing me
thanks and friendly greets

Hard to diagnose from a single minidump but it appears to be an attempt by your vga driver to write to read only memory ( a no-no). I would reinstall both your video driver and dcheck to see if there is a newer BIOS to flash.

i allready have the latest bios version according to the asus site. should i downgrade ?
i'm gonna reinstall the driver i have to say yesterday i update the driver so ( but i did have bsods before that update but never the video.prt one) should i downgrade the avg (ati) driver or just reinstal

i had 2 new bsod's this morning
at now moments i never had one after i logged in it was a system service exception and it also said something about neto.sys or something it went really fast so
and the other one was when i was typing my password to log in on my pc it was an irql les or not equal if i remember well.
gonna post the 2 minidumps
