Dell windows 7 factory restore after black screen

Hi I have a Dell system studio slim desktop, I used the "reinstallation DVD, windows 7 home premium 64-bit" disk to reinstall.
After the reinstallation, when it automatically reboots, the screen starts up where I can press F2 or F12 for boot options but after that and windows logo, it stays on a black screen.

For a little background history, the desktop had a power supply die and I bought and added a new PSU. After that it worked until viruses on my computer forced me to reinstall windows. Then this problem!
Please help! I have to write a paper!!!

You may need to do a more intense format to clear any crap left over from previous install, a recovery install does a quick and dirty wiping of the partition and fat tables.

There is a possibility that the virus is still on the HDD. Formatting the drive does not actually erase it, it just marks the sectors as empty, ready to be re-written.
First, make sure the new PSU is plugged in where it is needed. Ensure the CPU's heatsink did not get displaced/nudged during fiddling with the mobo. It sometimes happens; you can enter the BIOS and monitor the temps for a while there.
If it looks stable, then on to the next step:
Use a different system to download and burn a bootable CD with Killdisk; you can Google it and download the image, then burn it on a CD.
boot your Dell, insert Killdisk CD, reboot, select first boot device the CD/DVD rom, reboot. It should launch the killdisk utility. Navigate to the free erase utility, select your entire HDD (if you have multiple partitions, you can select the "root" of them, which is the entire HDD) and erase it as instructed in the wizard. It will take a while, according to HDD's size. Leave it alone until finished.
You have now a brand "new" HDD. Proceed to remove the Killdisk CD, insert Windows DVD and go ahead with the installation.
Good luck and let us know if additional help needed.
Good luck

So this "reinstallation" disk is an actual Windows 7 install DVD, or rather a recovery type of DVD which copies/extracts the contents of an image file to the disk drive?

Can you go into Safe Mode (press F8 during bootup)?

I have the option to go to the option menu when I press f8 but safe mode errors as it states I have to set up windows before I can access safe mode.

As to the type of disk I'm not sure. The quotes I used in the OP was quoted off of what was written on the disk
