System Hanging..?

I recently installed cpucool and have tried to overclock my FSB clock. My PLL is not listed in the provided list; it is an ICS 954102 and the provided list jumps from 101 to 103--there is no listing for my 102, but, they have the same multiplier of x14 (the 102 and 103) so my question is "Can I use the 103 settings to oc my FSB?

I clicked the + symbol to move the FSB speed up one single notch and my computer screen went black and took my to a black start-up screen asking me to press F1 or F2 to continue into Pheonix BIOS but I don't have Pheonix BIOS my BIOS are Dell A04 BIOS.

My machine is a Dell Dimension E310 with a micro BTX board made to Dell proprietary standards according to the Dell support site. My PLL is an ICS 954102 and my chipset is Intel i915P/i915G.

So, is my system hanging when it goes black; or, am I supposed to click the F1 or F2 to continue?

Thank you for any help.
