No display on soft restart

[Gribbles]

I've just upgraded my system to a Chaintech 7KJD mobo and Athlon 1.4GHz

Generally everything is fine - the G400 is perfoming admirably now I've something to push it a bit harder

However, the only remaining glitch that I have is that on a soft restart, the monitor reports no signal. The CDdrives & hdd spin up, but the system just sits there. This happens when choosing restart from Windows, doing a Ctrl-Alt-Del reboot, or even saving the settings in BIOS and restarting. The only things that gets the PC back is a hard reset using the reset switch ot shutdown & restart.

I've upgraded both the G400 bios and the award bios on the mobo.

I'm hitting the web to try to find a solution, but I thought I'd check here to see if anyone else has seen this particular problem...

I'm not sure if it is the G400 - but I seem to remember a post about this quite a while back. I have searched the forum, but I can't find anything relevant

Graham

What kind of power supply do you have in your system? Me, for instance, had a similar problem when upgrading my Duron 700 to an Athlon 1333 on my Asus A7V133. Changing the NoName 250W standard power supply to an Enermax 430W solved it for me. Also, some random crashes and system lockups were gone after that.

Can't remember the brand, but I bought a new case when I upgraded & the included PSU was approved for use with Athlons - main reason I upgraded the case in fact...

Maybe you should try the usual hard way of problem-solving:

Remove or unplug all components except mobo, vga, cpu, fans, ram, keyboard and power supply. If the problem persists swap your vga, cpu and ram...

It's also possible that your mobo doesn't like your sblive sharing the IRQ with the USB. I would check that first, my sblive caused a lot of trouble, although not sharing the IRQ, so I removed it and activated the onboard AC97 soundchip.

Have a nice evening

I would, but everything else is OK - I had enough of a nightmare installing the mobo - the manual had wrong jumper setting info!
Maybe when the honeymoon period is over (I'm enjoying playing with my new fast PC) I'll spend an evening

Hmm. Sounds reasonable. Although I do like my SBLive. Again I'll give it a go at a later date.

I'll post any results I get here, just in case someone else with the same problem comes looking

Are you overclocking at all? Or even running a 200MHz FSB part as a 266MHz FSB part?
Does your BIOS have a different CPU voltage than the default for your processor?

I used to have your problem, but that was because I was overclocking my Duron. When you first boot (and this becomes more of a problem during soft reboots) your CPU runs at the multiplier and voltages that its jumpers indicate. If it can run like that for a few milliseconds or so, then the BIOS kicks in and you get the voltage & ratio that you set there.

My Duron wouldn't boot at it's default ratio @ 133MHz FSB. I penciled the jumpers, so now the part thinks it has a ratio of 7.5, and a default voltage of 1.85V ( This also lets my MB crank the voltage higher, kewl). No more lockups on soft reboot for me.

I've not overclocked it at all yet. In fact, with it being a new install, I've kept everything bang on the line. FSB, core voltage etc are all as they should be.

I suppose I could try clocking back to 200FSB and see if it solves the problem....

there is a somewhat similar thread started by me. My G400 wont boot sometimes, with a no signal, and a long beep, 2 short beep post code. Just search for a topic with that in it. Or my name, I dont start too many topics. I have fired off an email to Matrox tech support about it. Best of luck, lets keep each other informed, if the probs are similar.
