Hi I've recently purchased a Gigabyte GA-VRX motherboard and I'm having some problems. I've fitted a Athlon XP 1900 CPU with a Volcano 7+ fan and the machine is switching itself off intermittently when running. Sometimes it will run for several hours before this happens but equally its as likely to do this after several mintues.

I think the problem is fan related because I've purchased a new power supply and fitted it and the problem is still persisting. When I fit the Volcano 7+ switch the rebooting problems seem to be worst.

The other day I did a test of disabling the Thermal temprature setting in the BIOS and the machine ran without any problems for about 4 hours. As soon as I switched it back the problems reappeared. I thought this might have been a known fault so I checked Gigabyte's website and they had listed a BIOS update for the motherboard so I've flashed the BIOS and now the machine won't switch on.

HELP!

Do I have a bad motherboard? Is the fan the problem?

You assistance would be much appreciated.

I have read of that happing after a flash on a gigabyte board . They replaced my board.Mine the fans would run but no post no bios no nothing

One other thing try and clear the cmos first this takes some time on this board before it will completly clear.
Good Luck

What did the BIOS say about the CPU temperature, was the CPU running hot or no? because my first suspicion is that the CPU is getting too hot causing the system to shut off. I wonder how many motherboards have to be sent back to these manufacturers before they get in their thick skulls to integrate a boot block into their BIOSes so people can recover from bad flashes, because few modern motherboards seem to have this feature (I have a 5 year old old Intel PII motherboard that has this feature!). About all you can do is check your motherboard manual to see if 1. The BIOS has a boot block and a corresponding recovery jumper on the motherboard that will allow you to recover from a bad flash (the clear CMOS jumper will do you no good) or 2. whether the BIOS chip is replaceable or soldered onto the motherboard. If it's soldered, you will need to contact Gigabyte and get an RMA to return your motherboard for a replacement. If you continue to have this problem even after the motherboard replacement then you have a problem with the CPU/Heatsink-fan, which seems likely to me.

The chips are soldered on and gigabyte has dual bios in case of such but I guess it doesnt work so good.

The BIOS chips on the Gigabyte Ga-7VRXP aren't soldered at all. What you do need though, is a PLCC chip puller tool to perhaps swap the bad BIOS chip with the back-up one (which will contain the previous BIOS revision). I am actually tring to get one to do the same job myself. The issue with the intermittent switching off I believe is something to do with the speed of the processor, that the motherboard cannot cope with. If you make sure the external clock speed switch (on the motherboard) is set to 100MHz rather than the correct 133MHz, you shouldn't have any problems, except, the CPU will run at a slower speed which is not why you bought an XP1900! Its a fault with Gigabyte's board. Blame them.

I have that board 1800+ FSB at 140 512 stick of samsung pc2100 and antec 350 watt psu .And mine runs fine bios is F8

I got my book in hand for GA-7VRXP.Wide range protection Status 1 Update ESCD failure,checksumerror,or reset occurs in main bios,just before OS is loaded and after power is on,and that wide range protection is set to enabled the PC will boot from backup bios automaticaly. They look like they are soldered in to me But I am not going to take the case side off to see as according to book you dont swap the chips

I have taken the motherboard back to the shop that I purchased it from and they have tested it and said that its a problem with the Motherboard (they couldn't flash it at all). Now for the weird bit...

I originally purchased 3 of the same boards for systems I was building;

Board one - which is faulty and now being returned to Gigabyte.

Board two - which I've since swapped (they supplied me the wrong one) for one with RAID (7VRXP)

Board three - which was for another system I was building for a friend.

Anyway I decided that since we had to return "board one" and we'd have to wait 10 days or so for replacement that I'd fit "board three" to the troublesome box so at least we could use it whilst waiting. The technician at the shop did the board swap whilst taking the original out and then gave us the system.

We get it home and plug it in - it is now doing EXACTLY the same as the original board!

If I power on the computer it will often reset itself within several minutes of running. It also dies during startup.

This is a new board! The power supply has been changed as well to a 400W (I had thought that the original 300W was causing a problem).

The only stuff that's original to the Mainboard/system is the RAM, Fan, CPU, Hard drive and CD-ROM RW.

This is the machine from Hell!

I am having the same problems. My Athlon XP2100+ will only run at 100mhz bus (1300 mhz). When I switch the computer to 133 mhz bus I get lock-ups at post or it will power up for about 3 secs then power down. I cleared the BIOS. I have the lastest BIOS version (F9). This is the version 2 of the board. I bought it becuase of Tom's Hardware's review of the board. I should have gotten a ASUS. Does anybody have a fix for this or am I going to have to replace this board.

Tried about every possible config with the four IDE controllers with almost no luck.

Promise controller reports
"MBUltra133 (PCD20276) BIOS is not installed because there are no drives attached"
even though it detects two drives! Won't work with either CD/DVD drive, but sometimes works with the HDD. Blue screen of death if I try to boot into win2k from the promise controller.
Computer reboots randomly- I think only when set to 133Mhz?
What should I do!!?!?!
Any advice appreciated.
