New machine Woes

[Tony2005]

I've just got a new machine, intially everything was fine, everything booted up, installed vista and all was good.

I then decided to update the BIOS version of the motherboard and things have been going down hill since.

The machine turns off suddenly for no reasona and no warning.

The motherboard is a Gigabyte GA-VM900M. The vurrent BIOS Version if F5, previous version is F2.

Processer is Intel Core 2 Duo E4400

So reflash the old BIOS. It's downloadable.

It's not shutting down for "no reason", you know. There is a perfectly good reason. Your job is to find out what it is. Check your PC Health settings.

Why did you flash your BIOS? Trying to fix a problem? Don't want to nag, but flashing BIOS is dangerous. Easy to knock your system out. Should only flash if you have a problem or need improvements from the new BIOS.
The lecture done, does it just shut off, no quick BSOD etc? After you flashed did you reset your CMOS jumper? You should do this first.
Then I would look at your settings in the BIOS. When you flashed it the settings should have reset to default. Sometimes the new BIOS may not overwrite the old settings and that can cause trouble also the new BIOS settings may be somewhat different, for example may be just a touch off on your memory voltage enough that you get enough vdroop and she shuts down on you. Could be you have low voltages to your memory or cpu. Check all of the other settings, memory timings, cpu etc to make sure they are correct.
Check the Gigabyte forums and see if anybody else has had this problem. If none of the above don't work, you can always re-flash. You may have had a bad flash, which is very common.

Well lesson learned.

I'm not sure of this 100% but something could be overheating, or the motherboard could be falsely reporting something is overheating. If I leave it off for a while the system is able to boot in to windows for about 10 min.

I'll report back as soon as anything happens

Thanks for the help

One quick thing.

I've tried two different psu (One point I thought the psu might have become bad) The new one makes the motherboard reportt the VCore to fail in the pc health of the bios, My one on this machine does not...

Well I flashed the bios to the original version....all is working fine now...lesson learned.

Thanks for the help!
