The problem with the graphics card

Hello! Decided to replace an old machine video card, bought a 440GT GF instead of GF 7300GT. Downloaded nvidia driver and rebooted the machine, after which the problems started. The task Manager shows 100% load on one core (the second is not higher than 10%). Stuck an old graphics card, everything worked without problems. Tried to remove driver problems also did not have any. Then I tried to put the driver from the disk that was included with the video card, I also put the previous version of the driver, one core was also loaded on 100%. The task Manager shows no active processes, system load (system idle 90-95%). Looked at the list of processes using Process Explorer, I saw that the system loads a process Interrupts. Googling it suggested that it is associated with system interrupts (I, unfortunately, says nothing).
What could be the problem in this case?

Windows 7 Ultimate
Motherboard Foxconn 662 7MA, Intel® Core(TM)2 CPU 4300 @ 1.80 GHz, video card GeForce GT 440.

Solution
Thank you all for the advice. Tried to install on a separate disk system from scratch, the problem persists. I only have 2 versions — either the problem is with the video card, or hardware incompatibility. Tomorrow I will try to exchange for another card and if does not help, then will have to conduct a deeper upgrade the computer.

And is it possible to put your new clip (GeForce GT 440) to another knowingly working machine? As a second option try in the BIOS to disable onboard devices like sound and network cards, different ports.
Unfortunately there are no opportunities where else to try to install it. - Akeem.Murray commented on October 8th 19 at 01:34

Well, Yes, it's a motherboard change, or to wait for new drivers =\ And sell the card to someone who is under the mother Board AM2\AM3+
That is the problem all the same in hardware incompatibilities? - Akeem.Murray commented on October 8th 19 at 01:36

Saw similar glitches due to the fact that the driver is not completely removed. Not that Uninstallers could not cope normlano, but even specialized driver's slipery pay, etc. Walesa somewhere sneaky Dllca and ruins everything.
My advice is to roll forward on another partition or disk clean Windows with a new videhoe, if the problem persists, then iron, if not - then it is necessary to look for the problem in OS combat.

In the nvidia drivers when you install there is an option "Perform a clean installation" (when choosing Custom (Advanced)).
