"Choppy", stuttering PC

Ever since I built my PC back in 2011, it has never really seemed to run smoothly.

It has always had a kind of stutter, or choppyness, to it rather than being smooth and consistent.

One example where I have noticed it is when simply opening and closing a new tab in Chrome. On the standard laptop I have it slides open completely smoothly every time. However, on my PC sometimes it will kind of jerk open, stuttering a few times as it opens. It's only slight, but it's definitely noticeable. (Happens even when I only have Chrome open and nothing in any of the tabs or anything.)

But it's not limited to just this. In fact almost everything feels slightly choppy. Even when just click + dragging the highlight box thing when just on the desktop feels like it stutters very slightly.

It manages to run intensive games at good FPS, and I always try to get a consistent 60fps altering settings and usually capped with V-Sync, so it's not like it can't run those games powerfully, but even then I sometimes do notice that it doesn't feel as smooth as what I would assume it should be, even with a solid consistent 60fps.

I've always tried to ignore it, and thought maybe it was just me being paranoid or something, but it's definitely there.

Things open and work quick, but not smoothly.

Since my original build, I've had a new GPU, RAM, and an SSD (which I have only Windows and Chrome installed on), and the problem still remains. Reinstalled Windows several times, including onto the new SSD.

My PC specs are:
Intel Core i5 2500K (@ stock atm)
Asus P8P67 Intel P67 Mainboard (B2 Revision)
Asus HD 7970 Matrix Platinum 3072MB GPU
Corsair Vengeance Low Profile 8GB RAM
Samsung SpinPoint F3 1TB SATA-II
Samsung 120GB SSD 840 EVO
XFX Pro 650W Core Edition Power Supply
Windows 7 64bit

What could be causing this? Could it be a setting somewhere that is set incorrectly? Faulty part? Possibly my monitor?

Really annoying problem that would be heavenly if sorted. Any help much appreciated.

What memory settings are you running? I would look at those first,maybe one or two clicks more vtt voltage would help
 
Still stutter if you disconnect the mechanical HDD? What about in safe mode?

Just tested, does still happen without the mechanical HDD. In safe mode pretty hard to tell, as click+drag boxes seem fine but Chrome is extremely laggy and choppy (far more so than in non-safe mode), and also the low resolution makes it hard to judge.

I've got them set at the correct timings for them (9-9-9-24), had a look at the voltage the other day in the bios and it's set to Auto, which was hovering at about 1.52 when I was looking before.

Bit of a long shot, but could this be related? My thread I made the other day about my RAM and settings, which I haven't had any answers for as of yet..
 
How much CPU/vtt voltage? Not dram voltage

Be sure all chipset and Intel rapid storage drivers are upto date
 
Idk,unless you look on intels website,I get mine off tweaktown forums,they get updated by stasio

Latest BIOS or beta BIOS might help also off tt forums
 
No mate.
You've got P67-based chipset motherboard with B2 revision which is bad. It causes SATA2 ports degrading over time which might mean "choppyness" of whole system once any drive is connected to SATA2 port. There was a big action of swapping B2-based motherboards for free, why you didn't react ? :)

I'm not sure how the whole system goes on with SATA3 ports only populated (try to swap HDD to SATA3 port), but for best result B3 chipset revision is simply recommended.

Yeah I know about my whole B2 motherboard issue. Never sent it to be replaced as never knew about the whole issue, only found out about it fairly recently unfortunately.

I updated my BIOS to as recent as I can with my board, but I know I can't do more because of it.

Would this include the Chipset and other drivers too? Or just the BIOS driver that I can't update?

Will check my CPU voltage in a bit.
 
What am I looking for with these programs?

Nothing special. You just waste your time IMO. Check HDD connection (swap all cables to SATA3 ports, if you are short of SATA3 sockets so leave DVD unplugged for this testing time) and see how it works then. Some reboot migh be required as Windows will remap SATA drivers & connections. If choppyness is gone = it means you need to change motherboard to P67(B3), Z68 or Z77.
