Windows 7: Comp wont ALLOW F2 for Startup

So it says clearly on my comp when loading F2 to get into the bios and what not, but it wont allow me to do it actually... immediately after that screen it just goes to a corrupted jibber jabber of colors which then freezes up until i reset and attempt to do this all over again. I am absolutely confused as i have tried doing the startup discs in it as well and nothing... ive tried F2, F12, delete, esc even though it says its F2. I don't know if this means my hard drive is corrupt and i need a new one or if there is gonna be more issues that i don't even know about, but this all happened last night at about 3 am while installing a new game and my comp kinda locked up.

Windows 7 Ultimate x64 btw

Corrupted video driver? Try tapping F8 repeatedly at boot, then select Enable low resolution mode (vga mode). Can that get you into windows?

Wont work for me... just tried about 7-8 times to do that as well and wont let me change any settings

Try booting from a Windows 7 install dvd or a repair disk and run system restore. You could also try startup repair and sfc scan.

System Restore

Startup Repair

SFC /SCANNOW : Run in Command Prompt at Boot

Ya ive been trying to boot right from the install CD, but it doesnt do anything but go to this screen... it acts like its not even in there and doesnt mention anything about it

Video card gone south perhaps. Post your issue in the hardware and crashes and debugging subforums.
