I don't know what to do anymore :(

Ok so i just finished building my FIRST PC, and i've had nothing but problems. First i couldn't get past the BIOS due issues with my hard drives and something to do with Marvin and no hard drive detected errors, which i think i have now solved. So i try installing windows 7 i get to the bit where it says

Copying windows files: check
Expanding windows files: 100% check
Installing features: CRASH
Installing updates:
Completing installation:

Blue screened on me with a MEMORY_MANAGEMENT error

So did some more research and found out it could be due to having to much ram, so i took 3 sticks out leaving 1 in 16GB down to just 4GB. Tried to install windows 7 again

BAD_POOL_HEADER I don't know what to do i cant even get into the desktop and my complete noobness around a BIOS isn't helping here are my system specs

ASUS P8Z68-V PRO/GEN3
i5 2500k
16GB of corsair vengeance
520GT
1 Western digital hard drive(forget the name something black) 1TB
1 Corsair force GT 120GB
Windows 7 home

I really don't know what to do anymore.

P.S every time i try and install windows again i see 2 partitions 1 called system and the other called primary so something must be installing on there?

try taking out the SSD, ive heard they can be problematic

try setting your drives up in ahci or raid mode if its in IDE mode (sata configuration) mix and match

Disconnect the Western Digital. Make sure the SSD is on a Intel sata port (see your manual) and set it to ahci in the bios. On post - the corsair should show a firmware version, if its not 1.3.3 then stop and update the firmware first. If its 1.3.3 go ahead and install windows.

Edit- I see people recommending to disable the marvell controller in the bios altogether. Probably not a bad idea.

Windows 7 64 bit takes up about 30GB of space. If you installed Windows to that drive, that is what is eating up the space.

lol, did u format all the memory(HDD & SSD) u had before starting? not sure if u HAVE to do so.
