Windows 7 Wont start. gets stuck at many different things

Today when I turned on my PC I noticed it took was taking VERY LONG to get past the "starting windows" screen. This has happened to me before so i just let it run. but after 15 minutes later I gave up and restarted. after that I tried launching startup repair. it got stuck a black screen with nothing but my cursor. I let that go for about 20 minutes and restarted again. After that I got out the windows 7 64bit instal disk and decided to reformat. Now the first couple times I put it in the disk loaded okay I guess. it got past "loading files" in a fairly short amount of time but when the black screen with nothing but a cursor on it came up, that took a Loooong time to get by it. Finally it did though. I decided I would try real quick the repair option the disk had. After that it got to the screen showing my hard drive with windows 7 on it, but that window froze. after about 8 minutes another, separate window popped up saying "Searching for windows 7" (I don't remember exactly what it said there, all i know is it was looking for a hard drive that had an installed OS of windows 7 on it) even though in the window under that one it showed that it found my HD with windows 7 on it

After that I was able to reload the cd and try and run the process to reinstall windows 7 and just wipe my damn HD. Unforgettably it got stuck at "Setup is starting" after clicking Install windows 7

I tried running safe mode. I got the advanced startup screen to load after choosing what drive to boot from by pushing F8, but that froze while it was loading files. It got stuck after a file name that looked like AVWRET (fille name off of memory sorry)

after running all those disks and nothing working I decided to give startup repair one more time. THIS TIME it got all the way to repairing. (after I waited 20 minutes for it to search for a problem) it decided it would do System Restore, never asked me to pick a time to restore to though. let it run and in about 15 minutes my pc restarted on its own (pretty sure it was because system restore made it do that, not a power issue)

Current state: Now my damn pc wont get past anything. where my pc gets stuck at if I run:...
Startup repair again: black screen with cursor
put a disk in and boot from that: loads files fine, stuck at black screen with cursor
Start in safe mode: unable to even get option to appear now. Every time I push F8 to get the advanced startup options to appear I get the screen saying which drive do I want to boot, I promptly choose my HD with Windows on it, and the only screen I get is "Windows Failed to launch." "run startup repair or start normally?"
Start Normally: Gets stuck at Starting windows

I have no idea what to do. hopefully someone can help

(Sorry for the very long post. My brother told me to post on this site and be VERY specific about what is happening)
