Hi.

I'm having this serious problem with my computer and its getting really annoying because it tends to affect almost all games I play, especially heavy games. Now I have no idea what to try anymore.

Problem: There is this sort of micro-stuttering or 'jerkiness' which almost feels like having 15-20 FPS while FPS counter says 59 (normal is 60). Sometimes FPS might actually drop to 15~ in even simplest of dialogues with no big fancy background landscapes showing, just boring small room with simple walls (Star Wars: The Old Republic)
I also feel there is this slight delay on controls during this occurrence in some games (Resident Evil: Operation Raccoon City, Dead Space 3).
I also have noticed loading times might be very high depending on the 'time of day' (meaning randomly). One specific occurance happened when I travelled into another outpost by taxi and game couldn't load the area on the fly by the time I arrived. It had to switch to loading screen for 15 seconds to get area loaded (Star Wars: The Old Republic). This sort of thing never happened before, and it only happened once.

This problem appeared when I moved into another apartment. Before that my machine had working flawlessly for over a year.

What I have tried (chronological order), none of them helped:
- Tried all graphical settings on minimum, no effect beside normal graphical smoothness increased
- Tried different graphic card setups (two GTX 570, one GTX 570, one GTX 580)
- Moved a game where problem was easily noticed into C: and detached other HDDs
- Reinstalled Windows on SSDs I had installed at the time
- Reinstalled Windows on another HDD I took from spare PC
- Purchased and changed motherboard and CPU
- Switched PSU into another one from spare PC
- Purchased new GTX 770s and run them on 2-way SLI
- Purchased new HDDs for everything except OS, also purchased new Sata III cables and changed them to all drives.

I build almost new PC and problem persists and its causing alot of grey hair. What I'm yet to change are DVD drive, the case itself and the memory, but I heard if memory is faulty I would get BSoDs, and I don't get those.

My rig when problem started to occur:

Motherboard: Asus P8Z68-V/GEN3
CPU: Intel Core i7 2600K 3,4GHz
Memory: 16 GB DDR3
Graphic Cards: Asus GeForce GTX 570 x2 on SLI
PSU: Nexus RX-8500 850W
OS: Windows 7 Home Premium 64-bit
Hard Drives: 2x 40 GB SSDs for OS in Raid0, 2x 2 TB HDDs for everything else

My current rig (Bolded upgraded):

Motherboard: Asus Z87-A
CPU: Intel Core i7 4770 3,4GHz
Memory: 16 GB DDR3
Graphic Cards: Asus GeForce GTX 770 x2 on SLI
PSU: Corsair TX850 850W
OS: Windows 7 Home Premium 64-bit
Hard Drives: 500 GB HDD for OS, 2x 4 TB HDDs for everything else

Thank you for any advices you might offer.
