how do i get to cmos?

You have been to Bios (or CMOS rather)
And we ( well I ) have spoken about CMOS throughout this thread (many times)

Are you saying you haven't been to CMOS yet ??? <-- Note excessive use of ? (normally not allowed, unless support frustrated!)

There are already too many replies to this thread, for me to go back to the start and say check CMOS

well thanks alot for your help i guess ill take it back to bestbuy soon.

When you first turn on your computer, you should notice a key to press like DEL or F2 (or something) to get into CMOS setup

Once you see that key (displayed on the screen somewhere)
Press it, within 3seconds, to get into the CMOS setup screen

Now, some old Bios revisions (or computers rather) don't display this key prompt
No doubt yours being one of them!
In that case you would need to work out (possibly through downloading the manual) what the key button press is (ie even if it doesn't show when you first turn on the computer, it still can be pressed)

At last once in CMOS, re-read this thread

edit:

wow give me a moment (ie your edit) I need a few mins to answer

ya its f10 to get me in bios settings but theres only soo many things there like onbourd devices um pci something im just not sure what to change but like i said i got to find out why windows has stoped detecting the hardware first.

If AGP is disabled, that would be the reason (as mentioned 20 posts ago) just slowly go through CMOS setup

You may need someone to help you, if you are unsure of things like PCI and whatnot

thank you for your help i wont keep you any longer.ill just wait and have bestbuy look at it.
