K7m+g400 I've tried everything

Had the exact same problem. Here's the solution:

You need to change the Voltage I/O setting on the motherboard to 3.31V. See page 19 of the k7M manual.

I tried everthing -- drivers, irqs, swapping pci cards in & out etc, etc.

Finally found the solution at www.amdzone.com.

Everything works fine now!

Interesting, that post on the 3.31volts. I have the crashes too. I thought they were related to my SBLive, but I'm not sure. I might try this setting.

I thought I'd post that msg from the amdforum, I looked it up, here it is:

OK,with the Asus board,check out the manual. On page 19 look at the VIO setting.It controls voltage to certain slots.The default setting 3.4 lower that to 3.31 I ripped out my G4MAX because of those problems you state and bought a TNT Ultra. Same problems. Someone suggested lowering the voltage and I havent looked back since. I just dont have the nerve to try the G4 MAX again since I have total stability now

I have tried the voltage thing too with no results, I'm getting win2k and are praying that things will work fine there since it works in NT 4

Just bought a new PC with ASUS K7 mobo and have replaced cheap card with Matrox G400TV (Marvel).

Seen suggestions on web that PSU/heat may be cause of stability problems but my configuration is below AMD recs and seems okay (Midi case, power supply 250 Watts (AMD rec 300), one case fan (AMD rec 2?), and processor heat sink/fan).

However my Marvel is generating lot of heat, & little space between it and Sound Card, so I'v moved Sound card into last PCI slot to provide Marvel with more air circulation.

Had no probs with booting/stability etc. I'm not a great gamer but no probs running anything (Matrox's TechDemo wouldn't run until AGP miniport installed but everything else did). I've only just put the cover back on so will check mobo I/O setting later (suspect its 3.4v) as supplier seems to have left most settings at default.

Could BIOS setting for AGP aperture size be a source of peoples probs? Mine is set to 64MB (can someone enlighten me as to what this means and if this is the best setting?).

My only problem with my PC was before I installed Marvel. Bought a MS Natural Pro Keyboard thought I'd try the sleep key - which should have been labled self destruct. On wake-up (seemed very reluctant!) lots of files had dissappeared, ran scandisk and recovered files, 6 directories plus contents minus long file names. Couldn't get some things to work so re-install Win 98.

Any idea of cause - BIOS/Win 98/disk settings? BIOS settings courtesy of PC supplier - SMART for Hard Disks disabled (default is yes); ACPI aware = no (default yes); Hard Disk Power Down = Standby (default = disable). Any advice appreciated.
