PCChips M590 motherboard troubles after BIOS flash

I have flashed BIOS of my PCChips M590 motherboard
(that mount a AMD K6/300 processor
+ onboard SiS6326 video card).
I get new bios from PCChips site (file 1209s.rom)
but unfortunatly haven't used flash upgrade utility
downloaded from that site (AMIFL815.EXE).
I have used instead AMIFL633.com that came with
software support CD-ROM of motherboard
(IDE, SoundPro, Vga and so on...).
This software seems to work fine BUT it did not make
a backup of old BIOS.

After CMOS clear, reboot and setting of the CPU type
in CMOS-Setup, all seem to work well and all PCI
devices are recognized but I have this problem:
at startup and even next, during CMOS Setup, screen
is instable. I can read what is in, but it seems like
something's wrong with video frequency sync, or like
if a radio frequency noise source stands near video

The noises are lower in Win95, but they do still,
expecially when I open a window with a black
background (e.g. Dos Prompt).
They become higher when I work with full screen
DOS tasks.

Can anyone help me???
