Windows 7: windows boot fail, can only enter BIOS

OS: windows 7 64 home premium
CPU: i7 3770
MOBO: ASUS P7Z77_M
HDD: Seagate 2TB
RAM: kingston hyperX 16 gb


alright, so i had an issue with deleting a steam folder that was corrupted. after googling a while i learned i should run chkdsk (checkdisk) when you rightclick on your hdd 'properties, under tools tab' etc.

so after that i just rebooted my pc and everything was normal, i could delete the folder. then i got a few windows updates, which i just ran. and rebooted normally. after a while, surfing a bit, then playing a videogame, my computer just crashed with bluescreen.

ever since then i couldnt boot up my pc normally again.
i do manage to get the BIOS screen, then the windows logo 'loading', but then it just gets me a blue screen again.


so the errors on the blue screen im getting is:
ntkrnlpa.exe
0xc0000098

and something along these lines:
STOP: 0x0000007E
(0xFFFFFFFFC000000S , 0xFFFFF88000E0DE3A, 0XFFFFF880009A8B78, 0xFFFFF880009A83D0)
wdf01000.sys - Adress FFFFF88000E0DE3A


it might be worth mentioning i had intel rapid storage techonlogy, which uses an ssd for caching. i thought this was the problem, and removed the ssd but no results.

I've tried some system recovery methods, like the bootup autofixer or system restore point but they failed aswell.

after reading something about MBR: ' bootrec.exe /FixMbr '
(source:How to Fix Windows 7 When It Fails to Boot)
i decided to give that a try.

i managed to get back to my desktop. but everytime i restarted i would just get blue screen again, then had to enter bootrec.exe /fixmbr in the command prompt from the recovery console, everytime.

then i decided to reinstall windows 7. and the installation broke down midway giving me the same error. now im stuck in a cycle where i just enter bios then get the error on startup, and then reboot.
if i try to go safe mode it comes with 'Windows cannot complete the installation in safe mode. to continue installing windows, restart the computer.'

and now i cant even get to recovery console/options anymore.

if i use my 60 gb 'corsair' SSD as HDD i get the same error.
for clarification ive been trying to use an 'seagate' 2 TB HDD first.
i've gotten this pc for only about 1 year....
