Thought i could tweak BIOS & Bummer was the result, help!

i just upgraded from a voodoo 3 to a ATI AIW 9600 so i was very happy to see the new performance of my computer, i also added two extra fans so i thought i would go and overclock my pc. My mobo is a chaintech CT-7aja0 with an AMD Thunderbird 1.01ghz, they were nice enough to include an easy overclock method in the BIOS and so i thought while i was at it i could tweak up a couple more things... riiiight ... so i went to a couple menus in CMOS Setup Utility at boot... In Advanced Chipset Features, i set the Optimized Defaults (which only seemed to change modem from disabled to enabled). I did the same in Advanced BIOS Features which made this change, my first bootable device was still floppy, second was still HDD-0 but my third had changed from CD-ROM to LS120 i thought it might be some sort of booster !?%^*#!, the computer should know better than i... i had read that OCing is to change the voltage basically so i also did that from Frequency/Voltage Control, i changed PC100 +0.5 to PC133 +0.5 ... i booted and nothing! i checked with a computer whizzer (than me) if i was right about this procedure being OCing and i turned out to be right, even though im still not to sure if i have to flip any switches on the mobo also... now here is the results i got...

1. floppy does not test at boot.
2. hard drives do test and so do CD-ROMS
3. processor does some work then stops working after a minute or two.
4. i cant see what that work is because i have no display output! (not even a c: prompt)
5. monitor stays on standby mode (light flashing)
6. im guessing processing doesnt get to BIOS start because keyboard does not respond (num lock is off)
7. windows install CD does not make any difference to the boot.
8. nothing to do with my AGP ATI, i tried putting the voodoo PCI back in & no display still

after thinking about it for a while and asking some people my friend said that i should take out my battery from the mobo (not the PS) ... im at work now so i wont be able to test out that theory until 8 hours from now so if anyone has any other suggestions please do throw one because the more i get the better i'll feel (my heart beats differently when my computer is not operating properly i feel like im having a heart attack at 22) ... thanks in advance.

You can also reset the BIOS by moving the jumper

on the 3 pin "connector" by the battery for a few minutes [read the manual] and then putting them back in the original position.

When things are back to normal. Go to overclocking forums and www.tomshardware.com and www.anandtech.com to learn all of the aspects related to overclocking. You have very much to learn on that subject. Too much to teach you here. You can even change the multiplier on that CPU with some minor surgery on the CPU, that allows far more OC'ing capability. otherwise you only have the memory bus and voltage settings.

I told you what an LS120 was in the hardware forum.

You increased the frequency of your RAM from 100 to 133 MHz, and most probably the voltage too. Your RAM modules probably support only 100 and the increase in voltage maybe too much for the processor that after 2 minutes it just stops working or locks up. Before you decide to change your RAMs to 133 be sure that your mobo also supports this speed. Return the setting to PC 100, and return also the voltage to 0.5 and it will work well. There are other mobos that will really allow incremental OCing in the Frequency Settings. Mine is a ASUS mainboard and I was able to OC it from 1.5 GHz to 1.73 GHz. What I did was increased it 1 MHz at a time until my computer locked up or did not start anymore then I returned to the frequency wherein my computer was still able to function correctly. Of course I also have additional fans. You could do better than that with a water cooling system. But did you do anything to the processor fan?
