GTX 580 BSOD and 100 % gpu usage problems

Hi, I have an EVGA GTX 580 that is suddenly giving me problems this morning. I tried to play a couple different games, and got crashes to desktop right away. I was able to get into starcraft 2 for a whole game, but it BSOD'ed after I finished. Using EVGA precision, I monitored GPU usage, and noticed it spike every few minutes to 100% just sitting on the desktop with nothing running...... I got a couple BSODs and monitor blackouts (screen just turned off and couldn't go back on) even when surfing the net. Computer very unstable.

Steps I took to troubleshoot:
Uninstalled and reinstalled video drivers
Run cpu at stock clocks
I can confirm temps are fine (less than 75c under load)
video card never oc'ed
I then switched the gtx 580 from system #1 into system #2 (listed below), and moved the gtx 260 from system #2 into system #1, No ISSUES NOW IN EITHER SYSTEM. This card has been working fine for a few months, and I didn't make any changes to my system lately. What gives?


System #1
Asus p6x8d-e
3x2gb Patriot ddr3 1600
Core i7 950
Corsair 750w tx


System #2
Asus P5q-e
2x2 gb corsair ddr2 1066
Core2Quad 9550
Pc Power and cooling 750w
 
I ended up reformatting and reinstalling windows, problems solved. I think it was a virus - exactly every minute, gpu.exe would appear in my task manager, gpu usage would go up to 100 percent, and my driver would crash. Anyone hear of a virus doing this?
 
Had a pentium 4 a couple years ago that did this.

Would load to 100% and stay there nothing open period.

Format fixed that as well.:\
 
What OS's are you running? One thought is that the i7 system if running Win 7 and the older core 2 system if running XP it could have been a Dx11 bug. Switching the cards would mean no Dx11 operating on either system.

Might have nothing to do with it, but it's something that occurred to me.
