Getting into Safe Mode

Specs: Window XP x64, 2.31 /4GB
Ok I just installed 2 ATI Radeon 4850 HD Graphics. I rebooted in Windows and now I get a pagefault_in_nonpaged_area error long before I ever get to a logon screen. I felt this was from the NVIDIA drivers still on there. However I have tried a number of things to get into Safe Mode...I havn't been able to get into Safe Mode using F8. I have tried in Grub right after chosing Windows and waiting for the load screen. So I am running out of ways to get into it.

"Are you're F keys disabled?"

Some keyboards have a button that toggles F keys on/off - if it does, it probably has an led that lights when they are enabled.
That may be enabled in Windows automatically, but not while booting, and you need to press the button.

Repeatedly press F8 very early in the boot sequence - don't hold it down.

If you have any bootable CDs or DVDs in drives, take them out - many bioses will boot the CD or DVD if you press ANY key at the appropriate time (often anytime within 5 seconds after the text prompt for that appears) while booting.
.....

Were you fiddling with the ram as well since you had the Nvidia card in it and it was working fine?
If you were, or in any case, try this:
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

Did you change which ram you have installed? Did that ram work fine with the NVidia card?
.....

You MUST connect an extra power connector from the PS to the mboard, other than the main one, and you MUST connect an extra power connector from the PS to each of the two cards. Did you do that?

What capacity does your power supply have?
You probably need that to be at least 550 watts minimum for two 4850's - see the specs for the cards on the card manufacturer's web site - that info is often under System Requirements, and it often also specifies a minimum current at a voltage the ps must be able to supply.

What chipset does the mboard have? If it's NOT ATI/AMD, then you can't connect the two cards together with a Crossfire cable connection - the mboard does not support Crossfire.
.......

Once you are able to press F8 and get the boot menu where you can choose a mode, if it won't work in Safe mode, or in any case, try Enable VGA mode - if that works, un-install the NVidia video drivers in Add/Remove Programs - you may not be able to do that in Safe mode.

Sorry had a busy weekend away from the computer.
No Fkeys weren't disabled...it was a timing issue. and I have resolved the actual issue at hand.

No. I wasn't hitting F8 soon enough after selecting Windows as the OS I wanted to use.

I have a Dual-boot machine with XP pro x64 and Ubuntu Linux 8.10
