Can't install Win 7 could it be graphics card?

[Bracador]

Hi there,

I have just been given a custom built pc and i'm not sure what everything is inside but from what i can see

Motherboard is a Gigabyte MA770T - UD3
Graphics card is a NIVIDA GeForce 8800 GTS
I can't read anything else for now.

I don't know what it is but when i was given this pc it was working fine with Win8, then something happened and suddenly i had lines and stripes in the background. Seeing as it was a new formatted pc i tried to reinstall win8 from the disk but the disk has a problem and won't install. Friends have advised me to go with Windows 7 as they have done so i bought both Windows 7 Prof including service pack 1 32bit and 64bit.

Steps taken...
Disk in pc, start pc, press any key.
Accept terms, click ok.
Enter language details, click ok
Click install.

Runs through set up, expands files and reboots all the way to the last part ' completing installation ' and then i get a black screen and nothing more, even when i left it for over 2 hours to see if it just needed time.

I understand it could be a ram issue so i now have only one board in at 4gig, but i get the same results, so i tried to take out the graphics card but my monitor connects using the graphics card port so i can't do it.

Is there someone who can guide me through this nightmare, i just want a machine that works.

Thanks for your time,
Sue x

Yes it could be the video card. The lines that were showing in Win8 could of been an indication of such. Do you have another card you can try?

Work through the steps for Overcoming Windows 7 Installation Failures - Windows 7 Help Forums to see if it will install. If so enable Automatically deliver drivers via Windows Update (Step 3) to run all Important and Optional Windows Updates to see what Display driver is delivered and install patches that may make it work better. Once you have the latest display driver from Updates compare it with the one available on the Nvidia Support Downloads webpage to try it if necessary. This may resolve your issue.
