Help! I'm having massive problems with an ASUS P5GD1-VM-UAY0Z motherboard and XFX PCI Express 256 MB, NVIDIA GeForce 6600 graphics card

I have purchased a ASUS P5GD1-VM-UAY0Z motherboard with a 400w PSU and a XFX PCI Express 256 MB, NVIDIA GeForce 6600 graphics card for my PC (I'm upgrading it for Half-Life 2). Now I have a HUGE problem. I put the graphics card in and Windows XP booted up no problems. The computer worked fine. Then, I  installed the gfx card drivers that were supplied with the XFX card. That's when it really hit the fan. After the install process I was asked to reboot. That's normal, except the shut down process took ages (about 5 minutes), and when the PC next rebooted, after 5 minutes in Windows XP the whole system shut down. Now I can't get anything from my PC, not even a BIOS boot-up screen. I know that the motherboard does have some failsafes that can cause the motherboard not to boot up (if the fan doesn't power up or it the CPU is over heated), but I don't think that is the case, but I may be mistaken

Please advise - any bits of advice or a solution would be really helpful. The ASUS support bunnies are really really crap

if you get power to fans, drives (ie noise, leds lit) but no screen, this does look like a bad BIOS.
if you get no power (silence) - check power supply, cabling and for loosely fitted parts. Could also be your mobo is shorting on the case. if so, rip it out of the case with just CPU/fan, memory and a HDD attached, then attach power and try it. If nothing then dead mobo -

e-mail vendor to arrange warranty repair/replacement....

Also, I have absolutely no idea what the mobo settings are as my friend did the install - I have no idea how badly overclocked it could be, so please keep that in mind.

Yes, I know, it's messy ;)
If the PC dont boot, then take the gfx card out and use another card (if it has onboard gfx, then use that), you can even disconnect the HDD and see if you can now see the BIOS and or POST screen, if so, now connect the HDD and try to boot up into safe mode and uninstall the display adaptor.

Now you shopuld be able to boot up to normal mode, if so you can now attempt to put your new grx card in and reboot. make sure all is well before trying to install gfx drivers and software, also do a windows update to see if there is a more up to date driver for the card.

have you tried clearing the CMOS?
with the power OFF, quickest and simplest method is to remove the battery, and leave out for at least 30 mins
then replace and try again.

if still nothing, sounds like a fault in the BIOS - return mobo to vendor time....
this happened to me 3 months after purchase, mobo runnning fine, then reboot to change boot priority and bang.

Remove the XFX PCI Express 256 MB, NVIDIA GeForce 6600. Reset the bios as mentioned. Start the pc with cpu and ram only. This mainboard has onboard graphics. Make sure the system speaker is connected so you can hear bios post codes. Also check if the cpu heatsink and fan is  properly connected and ram is properly seated. If you can boot the system now, do a system restore. If everything works, try putting th XFX PCI Express 256 MB, NVIDIA GeForce 6600 back. If the problem occurs again, return the card for replacement.
There is no industry standard among motherboard manufacturers for BIOS options.  Each motherboard manufacturer will feature different BIOS options which work best with their products.  The following recommended settings are BIOS settings when used with NVIDIA based graphic cards.  If these options are not present in your motherboard's BIOS, or differ in the way they are phrased, please consult with your motherboard manufacturer for further BIOS setting information:

Assign IRQ to VGA: Enable
PnP O/S Installed: Enable
VGA Pallet Snooping: Disable
PCI Bursting: Disable PCI Latency Timer: 128 Peer Concurrency: Disable
Video BIOS Shadowing: Disable
Video RAM Cacheable: Disable
USWC: Disable/UC
Pipeline Cache Write: Disable
PCI 2.1 Compliance: Enable (Only needed when using PCI graphic cards)
Passive Release: Enable
Delayed Transaction:Enable
VGA Boot Sequence:AGP (When using an AGP graphics card)
Graphics Aperture Size: 128MB (When suing an AGP graphics card)
AGP Turbo Read Mode: Disable
AGP Turbo Write Mode: Disable

It is best to disable the onboard video electrically via a jumper or dip switch on your computers motherboard or in its system BIOS.  Please refer to your computers user guide or contact your computer manufacturer for instruction on this process.

In the event that your system does not support the above, you may be able to disable the onboard video card in the operating system using the instructions below.

Make sure that the new PCI video card is not installed in your computer.

Windows XP/2000

1. Right-click My Computer and select Properties.
2. Click the Hardware tab, and then click the Device Manager button.
3. Click View, and then Show Hidden Devices.
4. Click the Plus (+) sign next to the Display Adapters category to expand it.
5. Select the onboard graphics controller under Display Adapters and click Disable. Click OK to confirm.
6. Do not restart the computer until the controller is disabled.
7. Turn the computer off.

8. Install your PCI GeForce card and follow the included instructions from the card manufacturer.

What you need to do first of all is to enter your BIOS,
in the BIOS disable your on-board graphicscard as this is currently conflicting with your new one.
Disable, save settings, boot machine and enjoy.
Your failsafe is called ASUS CrashFree BIOS2 and this protects your BIOS.

I get noise - fans drives etc, just no screen or beep. I'm going to take out the CMOS battery and see what I can do. It's less than 3 months old so it may be replacement time... shall post the results tomorrow 9am GMT (ish)
Sham HaqueSenior SAP CRM ConsultantCommented:
hmmm....3 months.
same as my EpoX board when it died, just 2 days after i threw away the box....i happily got a free replacement from my vendor (EpoX!!), though i had to pay for carriage there and back :-(

good luck.....
Sham HaqueSenior SAP CRM ConsultantCommented:
BTW - my EpoX board has a POST status indicator (2-digit LED, there's a list of the codes in the manual too - easier to understand than beeps or lack of them!) - these are really useful!
Have you installed the chipset drivers for your MOBO

This should be done before installing GFX driver

Here is all the relevant downloads for your board.

Note the one for XP servicepack 1 update

You said that you don't have onboard vga, but the model you specified does have.

Well, I went home last night and came to the conclusion that it's a bad mobo - took the cmos battery out, let it sit for 45 mins, tried again - nothing: have noise and power supply, hdd's whiring up, just no beep or bios boot up screen - looks like it's return to vendor time

Thanks for all your help - wish I could give points to all of you - it's been very VERY helpful
