Windows 7 installation and boot problems

Hello, I just bought a new custom PC, and it worked fine for about a month, running a 64 bit Windows 7 Ultimate OS. But one day I decided to install a mod for the GTA IV game. So I installed it, and ran the game. I then got a black screen and no response from my mouse cursor whatsoever. So I decided to reset my PC. After resetting my computer, it failed to boot windows and went into the Startup Repair loading screen. After this incident I was stuck in the Startup Repair loop.

A few days later, I decided to format my hard drive and re-install Windows 7. I put my Windows 7 installation disk and ran the installation until the disk partition menu, where I deleted and formatted the partitions. I'm not sure if this was the right thing to do, but I was following a forum on how to do a clean install of Windows. The installation seemed to be going alright until an error message popped up when windows was installing the features. The message said "Windows could not update registry data in the installation." followed by hundreds of message saying things like "The file or directory D:\Program Files\Windows Mail\oeimport.dll is corrupt and unreadable. Please run the ChkDsk utility." except there were all different directories every time. I have read a lot of forums about the Startup Repair loop and things related to windows not booting properly, but nothing seems to work in my case. So I took the hard drive to my IT teacher to get it formatted properly and tried to install a downloaded version of windows via USB. That didn't work either. The installation seemed to be completed, and told me to restart my computer to complete the installation. But when I restarted my computer a black screen popped up saying a lot of things, but the cause seemed to be "Windows failed to load because a critical system driver is missing or corrupt. I don't know what else to do, I have tried a lot of different methods, but none of them seem to work.

Check the hard drive with the manufacturer's diagnostic tools.

Hard Drive Diagnostic Procedure

If the HDD tests OK, unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install:

Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Did you follow the steps I gave you to reset BIOS to defaults and wipe the HD first? If so once you get online immediately enable Automatically deliver drivers via Windows Update (Step 3) to do all rounds of Important and Optional Windows Updates which may have important patches and drivers needed to smooth out performance.
