I had the hard drive cleaned on my old HP Compaq Presario 6000 since I was down to less than 50% free space (33GB)
I downloaded the files I wanted to keep to an external hard drive but my FMS (flight model simulator) didn't make it so I had to get another simulator.
I got ClearView but it needed a 3D graphics card.
I had to get an AGP card and got the GeForce 6200 LE.  I didn't want to wait so I did the install but couldn't get a picture, just a quick message that my monitor was out of frequency range and to lower the frequency.
The frequency was already at it's lowest setting (60 Hertz) and a call to the place of purchase said the lower frequenct is for an LCD, my VGA monitor needs 73 Hertz.  I don't have this option but I set it to 75 Hertz.  I still have no picture on my monitor.  Just a breif message that it's out of frequency range but now it says to lower resolution.  After trying several settings and getting nowhere, I took it back to the shop.
They got it working even though my settings are the same as when I started, 1024 x 768 pixels and 60 Hertz.
Maybe it just needed the driver installed but I remembered the gut saying that the driver could cause problems too so I removed it again and took it to the pros.
 
Now my monitor works and the simulator works. 
 
My poblem is that when I awaken my PC from standby mode, it takes about a minute to come on and the first thing I see is a blue screen that reads;  (only shows for about 5 second, I took photo)
A problem has been detected and windows has been shut down to prevent damage to your computer.
 
The problem seems to be caused by the following file: nv4_disp
 
If this is the first time you've seen this stop error screen, restart your computer.  If this screen appears again, follow these steps:
 
The device driver got stuck in an infinite loop.  This usually indicates problem with the device itself or with the device driver programming the hardware incorrectly.
 
Please check with your hardware device vendor for any driver updates.

This goes off and a few seconds later windows starts up, monitor comes up as normal and everything works OK...until morning start-up.
The first time I reported it to the guy that worked on it said "This is like a "ticking sound" on your car, it needs to be resolved or it may become a bigger problem.
 
I called Micro Computer Technologies, Inc,  where I had it installed and they said bring it in and they would check it out.
When I got there, the guy told me to do 3 things;
Check for windows updates - Done
Uninstall unecessary software - Done
Don't use hybernation/standby mode, just leave it on and turn off the monitor at night - didn't do.  I want it to function normally.
 
I ran an error check and it said to upload DirectX 9.0 or newer - I downloaded DirectX 9.0...no change
It also said
This sytem has recovered from a serious error.
 
Send error report - done.
 
It then took me to a page to update display adapter.
 
The guy that did the install said he didn't use the CD to download the driver, he went to their websit so he would get the latest version so that should be good.
 
I called the guy that installed my GeForce card and he said look for answers in google.
They didn't have PC's when I went to school so I don't even know what to ask for. 
All I know is what the Blue Screen said, check for driver updates. 
I did a windows update, "express install" and got - No high priority updates are available, check for optional updates in "custom"  I didn't go there.
While searching for a DirectX 9.0 install, I read something that led me to search for problems with drX and windows XP and found this page that shows compatability with Geforce 6600 and 6800.

My GeForce 6200 isn't listed BUT listed in the Features for the 6200 is "Complete Microsoft DirectX 9.0"   so it may already be on the card but I downloaded DirectX anyway.  Maybe  a conflict here?
  
 I opened the NVidia GeForce 6200 properties window and got
This device is working properly, if you are having problems, start the Troubleshooter.
I did but didn't see anything that would apply.
 
I called Microsoft Help 24/7 number, for $139.00  I can get 12 months of service...I said I only need one day, not 12 months.  I've gotten thru yrs without a problem untill now.
 
Any advise appreciated or I guess I'll try the shop where I had it worked on or maybe try a diferrent place.

The guy that did the install said he didn't use the CD to download the driver, he went to their websit so he would get the latest version so that should be good.

This sounds funny, but I would uninstall that video driver.

To uninstall the video driver the simple way, open the Windows Control Panel.  Navigate to and open the Device Manager.  Expand the Display Adapter item in the Device Manager list.  Right-click the 6200LE and select Uninstall.  Reboot the computer.

Once the computer reboots, install the driver which came on the CD which came with the 6200LE.

Why am I recommending this?
 
Contrary to popular belief, the newest driver is not always the best.  NVIDIA operates on the "unified driver architecture" method which means that any driver is supposed to work for a whole series of video cards not just one specific video card.  This is a nice approach, but does not always work great in practice.  Newer drivers don't always work well for older video cards.
 
I had issues with a 6200 PCI video card.  I had frequent BSODs.  I tried everything.  I underclocked the video card.  I tried to keep it cool.  Etc.  I finally contacted the manufacturer to seek some help.  They told me to get rid of the new driver I had downloaded and installed when I purchased the video card.  They told me what I just told you.  And they were right.  I went back to the driver which was on the CD and had no more problems.
 
Good luck.
