Decline in system performance

Hey there,

I'm new to this, so please be a bit forgiving if I missed out on something.
For past few months, I had several small problems with relatively new system (bought in May 2013), but as of now, my system performance seems to be declining on a daily basis.
Here is what I noticed:

After about 3 months of continuous use (Almost every day for ~10hours), I noticed that sometimes when I watched a video online, the sound would first stutter and at the same time, my mouse starts "hopping" (it moves at normal speed, but stops for a split second. Usually, this kept going on for a few minutes or until I closed/restarted my browser (then: Firefox, now: Opera).
Playing videos in VLC worked perfectly at first, but over time, it took longer and longer to fast forward or load any video.
Programms and folders open and close much slower than they did, when I move my mouse over the small previews that pop up from icons in the taskbar, the cursor slows down/is delayed until it has passed the preview. Also, Moving a window across the screen sometimes leaves a trail behind onscreen. (Although disabling and enabling Aero seemed to get rid of that for some time)
For the last ~10 days, whenever I open any Programm in Fullscreen (Firefox, Opera, Chrome, Word, Excel, Notepad, Adobe Reader, FoxIt, etc...), the screen either turns black for a brief moment or it takes a few seconds until any content pops up, scrolling down my mails in Outllok 2007 is slightly delayed and when I open any program that displays content a list of subjects, they appear one after the other and not at the same time like they used to.

Games that used to run perfectly without any hint at lag or slowdown at the highest possible graphics settings are now hardly playable even on low settings.(Examples include: Arkham Asylum/City/Origins, Crysis 1-3, Mass Effect 3, Remember Me, and even the first Battle for Middle earth...)
I already tried reinstalling my graphics drivers (currently 332.21), defragmented my HDD, ran Chkdisk and SFC, did several full scans with avast, Malwarebites and MS Security essentials (I only had one installed at the same time), installed any other recent driver update, tried to clean the dust out of my case (My room gets really dusty really fast...) , and googled for hours without finding any working solution.

CPU and RAM usage are usually around 80%max, even when playing, GPU temperatures are (according to EVGA Precision x around 41°C when idle and raise 61-70°C within the first hour of operation, no matter if I play, brose or write something)

My System: (Case: BitFenix Merc Alpha)

OS: Win7 Professional 64
Board: ASRock B75Pro3, Socket1155, ATX
CPU: Intel Core i5 3470 Tray, LGA1155
GPU: EVGA GeFroce GTX660, 2048MB, DDR5
HDD: Seagate Barracuda 3TB, SATA 6Gb/s
RAM: 1 G.Skill RipJaws-X, 8GB
PSU: be quiet! Pure Power L7 430w
Heat Sink: Scythe Katana 4
Display: HP 2311x
Peripherals: Logitech K120 Keyboard, M400 Mouse,C270 Webcam F510 Gamepad. (usually not all plugged in at the same time)

I tried to be as precise as possible, so please excuse the long text and thank in advance for any help with these issues.

Jep, you did, although I forgot to mention safe mode.

I had avast installed when everything started to get worse. I did a full scan with that (First normal, then in safe mode) and when this wielded no results, I tried Malwarebytes and now I have MS Security essentials installed.
 
try going into the msconfig section and stop everything not essential form running. do a reboot and see what happens. \\also......... shut down window update and auto driver updates. uninstall nvidia drivers. reboot. install only graphics driver and physx driver........ nothing else.

Thank you for your advice.

I did what you suggested, but it doesn't seem to work.

I did a test run with FurMark (1920x1080 Burn In test). The result was an average of 10fps (previously: 11fps)
Arkham City runs, but only in slow motion, an Wndow Transitions seem ever more choppier than before, opening a new Tab in Opera takes between 1 and 2 seconds...

If I'm not mistaken, that means either I did something wrong, or the casue for my problems is not related to drivers and/or background processes.

Could it be a Hardware issue? (Bottleneck, weak PSU, to much dust inside the case...)

I'd appreciate any ideas...

I found the problem. (Or, to be precise, a friend of mine found it.)
It was a process called vbc.exe that clogged one of my CPU cores and had the GPU running at full power even when it should have been idle.

I didn't notice it at first because it did not show up all the time in task manager, but it popped up irregularly whenever the slowdown got really bad. Renaming the file in C:/Windows/Microsoft.NET/Framework/v2.0.50727 solved the problem at least for now.
