Hello Everyone.
 
I built a computer five years ago with the help of Tom's Hardware.  It has worked great.  Windows 7 machine.
ASUS M5A97 LE R2.0 AM3+ AMD 970 motherboard and 
EVGA GeForce GT 630 2GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card
 
About two months ago, if I was to leave my machine running over night - in the morning the monitors would not respond - just black.  So I would reboot.  Then I started getting - One Long Beep and Three Short beeps after POST.  ASUS manual diagnostic is VGA not Detected.
 
To get the system to boot up - I just keep powering up until it works. Last weekend I replaced my PSU with the Corsair 450W CX450 - I had previously used a Corsair 430.  It didn't do the trick.

I cleaned out the inside and re-seated the Nvidia GeForce GT 630Card. Thought it worked at first but started getting beeps again.
 
So I figure I'll try a new Video Card.  Can you guys recommend a comparable card - the 630 is not available on New Egg.  I use two monitors.
No gaming just browsing and excel work.....

Thanks in Advance
Peter

The BIOS Version on my ASUS motherboard is AMI 1709 - 5/2/2013
 

Do you know the specific part number of your GT 630? Some of them had different configurations of video outputs, so knowing the part number would be helpful for recommendations. Also, please let us know what video connectors both your monitors use (DVI, HDMI, etc.)

Looks like the closest replacement to your GT 630 would be a GT 710 linked HERE. It is one of the few cards left that still has two DVI connectors and is great for office tasks or web browsing.

Thanks Adam - it looks like a good match for my machine.  Going to try the BIOS update first but have no problem laying out $55 if it fixes my problem!

I didn't leave my system on overnight because it was critical I had my machine operating today so I shut it down.  However, I have rebooted  numerous times since my BIOS upgrade and I have a strong feeling that may have fixed my issue!  I will check in on the weekend.  

It looks like the BIOS update may have worked.  My monitors did not disconnect overnight.  Thanks Everyone.

Try the card in another pci-e slot.

Just swapped card into black slot.  Browsing seems slower but maybe I am looking for it.  Will leave monitors on overnight and see if I get disconnected.  I did remove a fair amount of dust from the blades of the card fan and gave it a blast of air.  Will report back.  Thanks

Try reproducing the issue by testing the card in another system.

Hard to say if it's the motherboard or the video card. Testing the card in a different pc will tell you which one is causing the issue. If a different video card works fine in your system then the old 630 was the issue.

Hi Again - 
Hopefully ok to use this thread even though I said I was closing it....:)
Anyway - I continued to have the three beeps (VGA not detected) so I took Adam's (EVGA Tech's) advice and ordered a GT 710 for my dual monitor setup.  I am aware it could be my motherboard but I figured I could replace that next if this doesn't do the trick.  (I have an ASUS M5A(& LE R2.0 motherboard ~ 5 years old.)
 
I am currently using the EVGA GT 630 card.  The GT 710 is a shorter profile but I am assuming I still just use one of the two PCIe 2.0 x 16 slots.  
 
Just curious about the install. After I power off and install new card.  What will happen on reboot?  I have already downloaded the most recent driver for the new card but have not run it yet.  When I boot with new card will the system let me get to my desktop si I can run the new driver?????
 
Thanks
Pete

I run Windows 7 64 bit.
You should remove the Nvidia driver and install a default Windows driver first
Do you mean I should uninstall all of my current NVIDIA drivers via my Control Panel?
Install a default Windows driver
Is that resident on my drive by default?
If so, is that default driver sufficient to let me see my desktop, so I can run the 398.36-desktop-win8-win7-64bit-international-whql executable?

Windows will recognize a hardware change and want to install the latest NVIDIA Driver that's stored in the Windows Driver Store..Ain't no thing..Plug and play, basically.
