windows 7 startup problem pls help \(T_T)/

Hi I'm new to the site and decided that I had to try something to fix my problem I have been plagued by this for 3 years and decided to do something about it so i hope you guys can help.

Ok I should let you know I am veeeeery noobish to technology regarding computers which explains my name so there will be somethings i don't understand so please bare that in mind when explaining somethings to me.

Alright so I have a hp dv9700 and when i start it up it starts up at the bios screen like normal but for some reason it takes like a few minutes to continue on but i just wait that out no problem what my real problem is when i reach the windows 7 start-up screen after a little bit i wait for the logo to pop up in the middle of the screen and I 9.5 times out of 10 will see the most evil thing known to me an annoying weird dot in the very center of the screen that at closer glance looks like a reeeeeally small windows logo at first i tried waiting it out to see would load and no dice so I am forced to restart by holding the power button down and shutting it off I restart and the thing is I cant even run the windows repair option that it recommends every time because it just gives me a black screen after the little loading bar is gone so thats not an option I had this problem temporarily fixed before. I took it to my tech teacher at my last school who helped me repair the screen because it wasn't working before but replaced a wire that connected the monitor to the motherboard for free!!! so cool to that but i still had that startup problem so what he did was take a widows 7 os disc and I think he launched the repair option and some other stuff so that stopped the problem for like 2 months and then the little dot returns and i have no idea how to fix it but here's the funny part when I use my laptop there is a veeeery rare chance it will actually start-up and everything works fine till i have to restart for updates then i worried thinking oh god not again pls no not the dreaded updates I always put it off by putting the 4 hour delay but eventually it will claim my laptop and restart by itself and im stuck praying for a start-up again I HATE this problem it has me fearing the restart option please help in any way you can I have had to deal with this problem for 2 to 3 years
(if you read all of this thanks for reading my ridiculously long post)

 

Windows was already on the laptop when i got it and as for the drivers i went to the device manager and there doesn't seem to be any yellow triangles (also sorry for the language)

 

Have you tried examining your BIOS settings to see that they are at the defaults for your system?

Since this is costing you much time anyway, have you tried reformatting your C drive (and losing everything on it), then reloading Windows 7 from your installation CDs?

 

how do i check the bios? also i cant reload widows since i dont have a windows os disc and i kinda don't wanna wipe everything on my computer

 

You can try that Windows disc based Repair option again. There is a place for legal downloads of Windows ISO files, see the link below. Burn the image to DVD using right click on iso file > Burn Image

I didnt even know you could do this I'll see if there any blank DvDs around that i can use i remember my mom had like a stack of those somewhere and if that doesnt work I' ll see if the flashdrive option works I'll get around to it tomorrow
