Monitor going to sleep then BSOD and reboot. .DMP can someone read it?

I have two Dell Optiplex 170L desktops that had XP and I just installed Windows 7 as well as installing different video cards (Nvidia GE Force 6200 with 512mb) for both Dells so Windows 7 would work.

Both Dells while browsing the internet with IE11 or Firefox are randomly flashing "monitor going to sleep", then it goes to BSOD, reboots and creates a dump file. I have the .DMP file attached if someone can read it to point in the right direction of the failures or suggest the next step. I suspect the video card has something to do with this but I'm not a pc guru.

I believe I have the latest video card drivers installed - GE Force 6200 driver version 9.18.13.774

Dell Optiplex 170L Intel P4 3.0gb with 2gb memory
Microsoft Windows 7 Home Premium
Version 6.1.7601 Service Pack 1 Build 7601
Western Digital 80 gb drive.
BOIS version/date A07,1/21/2005

Thanks for the help.

Update your graphics driver to the latest version here

Drivers | GeForce

Code:

Stress test your graphics card with Furmark

I recommend running it for around 30 minutes

   Warning

Furmark will increase the temperature of your GPU rapidly so keep and eye on your temperatures

Thanks for the reply. The PS is 250 watt. I know once the Dell was only powered up for less than 10 minutes and it failed with the "monitor going to sleep, BSOD and reboot.

I just looked to "Install the NVIDIA DRIVERS 314.22WHQL only" and it is listed for 64 bit and my PC is 32bit.

Should I still download and try?

I downloaded the driver you mention ( NVIDIA DRIVERS GeForce 314.22 Driver WHQL) however it failed saying no hardware compatible installed for this driver (or words to that effect) so maybe I have the latest version installed now. I'm using GE Force 6200 video card. If you know of a better PCI card (PCI only, no PCI-E because this Dell 170L only has PCI slots) that will work please let me know.

Next I ran Speccy and attached is the screen shot. The graphics card looks to be running cool.

Then I ran Furmark with no issues and the temp only changed from starting at 39c to 48c. Screen shot attached.

I did look up some specs and saw where the 250 PSU should work with this Dell and the GE force card but I'm open for whatever is next.

I'll keep researching so your help is appreciated.

Unfortunately I only have remote access to either one of these Dell 170L's so my screenshot isn't showing the best graphics. I'll try to talk my brother through the Furmark process locally to the Dell and take another screenshot.

As far as the on-board graphics card it's not compatible with Windows Aero or so the Windows Advisory log shows but I might get my brother to move the monitor cable over and try it out. At this point I don't know if Aero is even needed with W7 but I'll browse around on that one.

Thanks
