Windows 7 64 bit install problem

Run a memtest from the BIOS to check if there are no problems with your RAM.
Try clean installing again, after formatting the HDD. It the problem persists, swap the HDD with another one you might be having. If the OS loads on the other one, you have a bad/corrupted first HDD, which you'll need to get replaced.

Thanks forgot to save when i switched to ram overclock setting so it was displaying 1333 instead of 1600

What are the BIOS settings for the hard drive? (ATA or AHCI)?

You need to restart your computer using the installation disc. If you do not restart your computer from the disc, the option to repair your computer will not appear.
1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer using the computer's power button.
2. Do one of the following:
· If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
· If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold F8.
3. On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press Enter. (If Repair your computer isn't listed as an option, then your computer doesn't include preinstalled recovery options, or your network administrator has turned them off.)
4. Select a keyboard layout, and then click Next.
5. On the System Recovery Options menu, click a tool to open it. Means select System restore option.
