Windows 7 Video Hardware Errors, frequent crashes, screen freezes.

"I tried clean booting on my desktop, and I couldn't even get to the log in screen, computer just crashed over and over."

I assume this was only when the Nvidia drivers were installed ?

"do you think its worth trying Treexy and reinstalling all over again?"

Only if you did not use Driver Fusion already. While I mentioned I only use it when there is

potential of corrupt driver install, your situation would call for it's use. Getting a good clean

install of the graphics drivers should rule them out as the cause of your problems.

It's still difficult to say where the fault lies. The top three suspects would be the gpu, psu and

motherboards PCI-e slot or controller.

• Without testing equipment the only way to test the gpu is to try it in another machine.
• The motherboard could be tested if you have access to another card.

If caught earlier the card could have been returned to the retailer. This may still be possible if the

retailer accepts it. Otherwise an RMA to the cards mfg, which retailer will sometime facilitate for you.

"And how could I monitor my psu's voltage?"

You can monitor the stability of the voltage to the motherboard, but I don't know if there is a

method to measure the stability of the current delivered by the psu's outputs other than taking the machine to a technician who can use a voltmeter, or maybe Oscilloscope,  to test it.

MSI Afterburner  has a Voltage monitor for the graphics card. The graph will help determine if

the card is switching from 2D voltage to 3D voltage.

• You can save a log to see if there is much  variation of voltage when in either 2D or 3D modes.

When I save a log file with my current card it shows  2D and 3D voltages.

In my case these equate to 0.806>0.850V / 2D  & 1.050V / 3D (game running) .

• Note that the first decimal place should not vary.
• Note that if you select too many monitors the Voltage reading in the log file can be difficult to

read, so best to just log the Voltage for the purpose of this test.

You can read the log file with Notepad.

Speccy has monitors for the motherboard voltage (gpu as well, but I don't think is does a running log file).  There should be only very small  changes on the motherboard voltages.

Hi,

Finally got around to doing some troubleshooting today.  I tried clean booting on my desktop, and I couldn't even get to the log in screen, computer just crashed over and over.

I don't think anything is wrong with my driver installation, I have uninstalled, rebooted, and reinstalled with only the components I need multiple times now.  I am not sure however if any of my drivers are corrupted, do you think its worth trying Treexy and reinstalling all over again?

Also, I can confirm that my computer runs fine on integrated graphics.  All my problems disappear when I remove my Nvidia graphics card from my computer.

And how could I monitor my psu's voltage?

Thanks for the help!

No worries. See you when you return

btw - while I may have made some disparaging comments about the psu, I'm not suggesting

you run out an replace it without knowing it's faulting (as people sometimes read my comments).

Cheers -

Thanks again for the quick response.

I will be very busy for the next couple of weeks and will probably not have time to do any troubleshooting for a while, so I just wanted to let you know that I will eventually get around to your suggestions and post back here.

Appreciate the help!

"How would I find out if my power supply is having issues and not my graphics card?"

Without proper testing equipment it's hard to do. You can monitor the voltage to see if there

are big spikes or drops.

You could feel for heat from the psu exhaust, but that's  a subjective test.

• If you can test the card in  another machine and it's OK, and you don't get TDR when

playing with the integrated graphics it could come down to motherboard PCI-e,  or psu.

 - However, While you may be able to run games etc with the Integrated graphics this does not rule out

software conflicts with the Nvidia drivers. Try running in   Clean Boot .

 - Just to verify your driver install is clean -

Uninstall all Nvidia graphics driver components via Programs and Features - reboot.

Run Driver Fusion/Sweeper (Generally only required with a corrupt driver install) - reboot.

Install only those parts of the Nvidia drivers you use (I only install the driver and PhyX) - reboot

• If you use the option to receive emails for your thread and didn't read the part I edited out

about cheap psu's you may want to read that.

Having the extra watts over minimum is good, but that is a low end model and they don't tend

to last under the stress of extended gaming.

I see a few people in the Newegg reviews commented on the short lifespan of your psu.

This is why gamers tend to go for quality model psu's  ie - 80+ Bronze efficiency or better, and

with Japanese capacitors.

Regarding Furmark - I follow Nvidia's line - They do not support it because it places artificially

high stress on the clocks and voltage of the gpu. Avoid using Furmark, or only use if for a couple

of minutes. The best/safest stress test for a gpu is games.
