New Video Card caused high CPU usuage coming out of low power state

I recently updated my graphics card to GeForce GTX 650 Ti on my custom built machine. Now, whenever computer enters, and then comes back out of standy, or hibernation, it causes CPU usage to jump to around 90 - 100% and makes computer unusable to say the least. (Note: CPU not GPU)

First what I've tryed:

- All drivers, for all cards, are up to date
- Did a clean reinstall of Windows 7
- Flash BIOS to most recent version (which unfortunately is 2012)
- Updated Chipset drivers for motherboard
- Ran a performance test, test couldn't make it pass the 3D Graphics portion, it caused the same high CPU usage.

What I haven't tryed:

- Installing card in another computer (not really an option for me right now)
- Checking PSU


The performance test I used was from Passmark and it makes me suspect something is up with DirectX11 when it failed the 3D portion. Does anyone have any other ideas or troubleshooting I can try?

Thanks in advance

PS. I did a simple search for this before posting and couldn't find my answer. I will continue to look through the forums as well

thanks, I'll keep plugging away and any other help or tips are welcome as well.

and as for RAM speeds per CPU-Z

Type DDR3
Size 8 Gb
Channel Dual
DC Mode Unganged
NB Frequency 2345.4 MHz

Timings

DRAM Frequency 465 MHz

Thanks for the link badger906, I used the program and all was green, then I forced the computer into sleep mode, when it came out of sleep, the DPC Latency Checker was in the red over 16000, but then jumped back to green and stayed there.

If I understand the program right, I am to disable drivers until I find the one causing the problem. However, I know the problem lies somewhere within the new graphics card installation. And I know that whether it's a windows installed driver or Nvidia installed driver the problem persists. Is there a way to find the conflict without going through all disabling/enabling?

Sometimes I can get the problem to repeat, sometimes I can't. The only constant I can say is it ONLY happens when it comes out of sleep or hibernation. I can restart computer and the thing runs like a champ all day. Leave it on all night, and as soon as i start a video, drafting program, game, blender, any kind of graphics program...it just falls on it's face with a system interrupts.

Another thing I've tryed...

I downloaded the Windows Performance Toolkit and tryed to record using the Windows Performance Recorder. Since I'm using 64 bit version, it had to disable the Paging Executive. I tryed to run the Passmark test previously mentioned again, to record where my last CPU usage got high, and it went through with no problems this time.

I thought I had stumbled onto something by having the Paging Executive disabled but after reenabling it I was still able to pass the test. Not able to recreate problem.

Update:

It no longer seems like it only happens coming out of low power state now. I've had it happen several times just using web browser. I've uninstalled drivers again, reseated video card, and reinstalled drivers. We'll see if the reseat is a possible fix.

Shouldn't matter which PCIe x16 slot i use should it? And shouldn't matter if my MOBO is PCIe 2.0 and the new card is version 3.0 should it? Should be backwards compatible.

I'll keep the board updated to hopefully help other users as well, and any other tricks to try are appreciated.
