error code 0x80070057 while installing W7

Hi,

So I installed windows 8 but I didn't like it so much, no problem so far.
But then a few days ago my laptop freezed during the bootup and when i turned it on it was like an half an hour to start and then when I got into the dekstop everything was running so slow! You couldn't even open textpad or something. So I stopped my downloaded windows 7 installation cd into my laptop and did everything till i came to the partitions. There (as I read) deleted all the partitions and made 2 new ones( 1 for windows and 1 for games and so on. Then I click on next and i get a error code: something like : couldn't format the hard drive. error code 0x8007005
I tried the DISK PART thing and nothing other happened.
I tried to do in the BIOS from IDE to AHCI and backwards, nothing worked.

What am I supposed to do now?
Thanks in advance!
(sorry for bad grammar if there is any, I'm from Holland)

By the way I have an Asus n56vz-s4035v.

Work through the steps for Overcoming Windows 7 Installation Failures - Windows 7 Help Forums

If these all fail, then test your HD with the maker's HD Diagnostic extended CD scan.

Allright, thankyou very much for your advice!
i'll do it tomorow after school, it'a now 22;50 here in Holland

at step 6 in the troubleshoot menu when I entered; format fs=ntfs label="windows 7" there came 0 procent and it stayed like that for 1min and then there came a error saying; there is a mistake in the diskpart: the parameter is uncorrect/wrong. (own translation from dutch)
please help?

Starting to look more like a disk problem. If you can't get it to format I'd test the HD with maker's HD Diagnostic extended CD scan, followed by Disk Check from the installer's command line.

Can someone tell me what hard drive I have on my asus n56vz-s4035v so I can do a hd test and In case i need to buy a new one if it's broken

I saw in another forum that in stead of clean i also could use clean all so I did that and them am error came that said; there is a mistake in the diskpart; the device is not connected.
Does this mean I only need to reattach the sata cabels or something?

no one?

I tried Seagate tools and it couldn't find a Hard Drive?
Please someone help.
