After 2 bad a7v333 I get a ga7vrxp Had no problems with ga7vrx still works great. I install OS and run updates update bios and have to disable promise as I have no raid I install norton internet security and run updates Rebootd each time. Updated via chipset drivers to 4.40 first thing. Then installed nero 5.5 and related incd ect .Then went to thier web page and ran updates.Then rebooted and got a blue screen stop error says bios not acpi complaint. I reboot and get same message. I reboot and go into bios and disable memory stick (i dont have one) Then look at voltages in hardware monitor and notice that they are all over the place Sometimes less than 1 volt. I reboot and nothing no bios just black screen no beeps. I unhook everthing except hard drive and memory and try a different AGP card still black screen no post no beep. I go and get a new 350 watt PS still nothing .
System specs now Ga-7vrxp, 60 gig IBM ata/133 7200 rpm , 1 stick of 512mb ddr sdram samsung, AMD 1800+, Yamaha 24x10x40 CD-RW,Light-On dvd-rom,Teac or panisonic not sure 3 1/2 floppy,Antec 350 watt power supply. I know the moniter is good as I am using it right now.

Reset your BI/OS, Ron. Drain the CMOS and reset to it's default configuration. Then try and boot again.

~ The manual said "Requires Windows '95 or better" I installed Linux!

your power supply could be at fault

I think that is the conclusion we have come to since the asus board I had so much trouble with works fine in another case. We are speculating that bad power supply fried the gigabyte board. I now have a new power supply as stated in first post and I did try and clear cmos even took the battry out for 30 minutes or so.I have another ga7vrxp on the way and left my old power supply at PC shop they think it might be bad also and have been very cooperative through this whole ordeal. I will post back next tuesday or wensday and let you know the results.
Thanks to All

I am having the same no post black screen :(
I *JUST* bought the mobo (revision 2.0), CPU (xp 2000+), and ram (512 samsung pc2700 cl2.5).
I put it into a case where 10 minutes before, everything had been working fine:
Enermax 430w PS (1 month old)
MSI/Nvidia GeForce4 ti4200
SB Audigy Platinum

Any ideas?

Well, it's seems all of us suffer from the same problem. I too have a GA-7VRXP and also get the black screen. I haven't updated the bios and have tried changing the CPU, RAM and PS but still, no luck. One thing I noticed is that the mouse remains powerd up at all times but the keyboard seems to get no power at all when the system is fired up. Have any of you tried calling Gigabyte representatives to see what the problem is?

Check the Revision of your motherboard. If you have 1.1, take it back. They have voltage problems which have since been fixed (apparently).

That could solve all of your problems. I have Revision 2 and I've never had the black screen problem.

I got mine replaced it was a rev 1.1 also but it works fine. I added a 2nd harddrive and now I have a poping screeching noise on log on and off and when playing Cds

I have the same issue...

I have just built a system using the Ga-7VRXP + AMD XP 1800+ and only after a month the Hard drive dies. After replacing the drive the system booted up normally but recognized the new drive WD 120gb 8mb cache as only being 80gb.

After being thoroughly confused I just took everything out and rebuilt the system. But this motherboard seems to be very picky on which screw holes you use to attach it to the case because it won't power up if it doesn't like the hole (very strange). After figuring that out now I get this same black screen without a POST or anything. I know all the parts work because I tested them in other systems. If it was the CPU I would still get a POST right?

So far I : Reset the CMOS, unpluged and repluged everything 20 times, used bare minimum parts to boot with, checked PS, tried to boot both inside and outside of case.

Ok - I got my revision 2 board to work, and now it's been running for 3 days nonstop without a single crash or hiccup.

First - if you are getting a black screen (no post) on boot, make sure the S1 jumper is set to be 100Mhz, not 133. Yes, your CPU will be running at a slower speed, but it's only temporary - read on.

In the bios, choose load fail-safe settings.
Then go to hardware monitoring and change the vcore from normal to +5%.

These changes should make your system stable enough to install windows.

THEN run the gigabyte @Bios utility and download the lastest bios (version F10).

This will allow you to flick the switch back to 133 and not get the black screen on boot anymore.

My Noteable Bios Settings:
-- Bios Features --
smart: enabled (works for my ibm drives)
interrupt mode: apic

-- Chipset Features --
top performance: disabled
fast command: normal
config: enabled
frequency: auto
command rate: 2t
agp: 4x
driving: auto

all usb

-- Power Management --
ignore all of these irqs
instant off

-- integrated peripherals --
ide controllers: both
channel 1: ata66/100
channel 2:auto
disabled all others, except USB 2.0

-- Hardware Monitoring --

--------- System Specs -----------

today I exchanged my 1 piece of 512 meg DDR333/PC2700 Samsung RAM for 2 pieces of 256 meg DDR400/PC3200 Kingmax RAM, and I am now able to set all the ram settings to the most aggressive.

System is rock solid.

Of course, the ddr400 ram only runs at 333 due to mobo limitations, but i think it gives the system the extra headroom it needed for the aggressive settings.

-- Chipset Features --
top performance: enabled
fast command: ultra
frequency: 333
command rate: 1t
