Adjusted BIOS now doesnt BOOT UP!

[lytalbayre]

So, I have:
a Gigabyte GA-7VAX Motherboard
A Athlon XP 2200+ Chip
512 MB PC3200 Samsung memory
Soundblaster Audigy
GF4 Ti4200 Video Card
A few extra PCI cards...
Running on Win ME
What I did:
I adjusted the clock speed of my cpu in
the BIOS of my computer. Everything was
fine before I did this. I adjusted it
from 133 to 135 mhz... not even that
big of a deal. I also adjusted the ram
speed to 200 mhz (I have done this
before with no ill effects). I think
it is the cpu clock speed that is making
my computer go nuts.

What happened:
Now my computer will not boot up. It
will not even get to the boot up screen
so that I can get into my bios and
change it back. When I restarted, the
screen was black, and every few seconds
a beep would emanate from the pc speaker
Also, I would get a message on the
screen saying there is no signal.

What have I done, and my thoughts:
I have opened the case and turned it on.
All the fans and power to drives are
working. I have noted that when I
first turn on the PC the harddrive LED
does light up, but then turns off after
one or two seconds. I have changed the
dip switch on motherboard to manually
adjust cpu clock speed to 100 mhz, but
it is still the same thing. My other
thought would be to use the reset
jumpers on the M/B to change the BIOS back
to factory setting(I have not tried
that yet).

My Questions:
Does anyone know where the reset jumpers
on the Gigabyte Ga-7vax/xp are located?

Does anyone have any theories on what
has happened to my computer? And maybe
how to fix it?

Could I have fried my cpu with such a
small clock speed adjustment?

Thanks guys!!!

ANy and all help would be tremendously appreciated!!

All jumper settings should be in your motherboard's manual. You do have that right? Sounds like you adjusted the FSB to where the system is gonna bark at you. If you've already gotten the memory tweaked out and it's at it's limit, raising the FSB even slightly may cause errors. The other possibility is that your particular Athlon just won't OC.

If the jumper settings don't work...
You could try holding down the [Insert] key and booting the system. On some boards this lets you boot so that you can get into BIOS and change the setting. Obviously, this would be more preferable than a total reset, but not every board has this feature.

Lastly, if you don't have the manual...I see you can get online, so hit up www.giga-byte.com You should be able to get the necessary info ya need.
