Graphic and Audio Slowdown, unsure if software or harda

Operating System
Windows 7 Professional 64-bit SP1
Intel Core i5 4670K @ 3.40GHz 33 °C
Haswell 22nm Technology
8.00GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
MSI Z87-G45 GAMING (MS-7821) (SOCKET 0) 29°C
SMS23A550H (1920x1080@60Hz)
Cintiq 24HD (1920x1200@59Hz)
2047MB NVIDIA GeForce GTX 750 Ti (ASUStek Computer Inc) 34 °C

931GB Western Digital WDC WD1002FAEX-00Z3A0 ATA Device (SATA) 35 °C

Optical Drives
No optical disk drives detected
Realtek High Definition Audio

So I've had this problem for nearly 8 months with no solutions I've found anywhere working. While using my computer, sometimes randomly and others seemingly just when under a lot of workload (playing Final Fantasy 14 or using my Cintiq 24HD)

It will suddenly drop in performance. Sometimes, but not always, it will begin with the screen going black, and the monitor searching for input. Upon returning to a display, often Chrome will be a window with just blank unclickable screen inside the borders. Over time it will refresh, or black out again and come back useable.

If it doesn't start this way, while in game or out, It will begin with the visuals and audio kind of "clipping", there is no proper descriptor I've found. The FPS basically drops from 70 to 15-20, and the sound is basically coming in at that rate as well. It eventually devolves to the point where I have to exit or restart my computer. Sometimes it affects computer-wide performance, sometimes just exiting the game fixes it.

I know my computer is able to play it on average settings, because sometimes it will play just fine. But the issue returns day and day again and I haven't been able to figure it out. Thank you for your time!

Actually, many gamer boards ask that.

Even that machine will slow under load. However while it was nice for you to post temperatures it's often a sign that you will have to write a lot to get the PC builder (you?) to just do the work of redoing CPU/GPU/all heatsinks then go over what could be software or driver issues.

The dropout is my clue it's time to do all the usual work and not waste time on software yet. Here's a nice article on another GPU. Nice pictures on what to do.,3678.html

Thanks for the response, still have questions!

I am the builder actually, yeah. I learned some in my first years of collegiate highschool but I graduated and started a business degree instead. So, there is a very good chance when I built this PC last year, that I've been doing something wrong the entire time!

So other than re-applying GPU or CPU thermal pastes, what else in hardware could be affecting this? Low RAM?

My HDD sectors are healthy.

Or just like you said, the i5 Haswell and GTX 750 are just low end and I should buy better parts?

I'm going with no to a lot of points.

1. Low RAM.

I continue to find 32 bit issues on games. I don't mean bugs but the games are put out in 32 bit executables so that means in Windows it runs in its own 2GB memory space. Your system has 8GB of RAM on the CPU and a current tech 2GB video card.

Simply no.

2. The GTX 750 should take sudden drops like the ATI did so I can't guess why you are passing up on prior lessons here. You can skip the GPU work if you point a fan at the open case to get by for now.

3. You have some USB things hooked up that could cause odd delays. One of the things you learn is to unplug USB 2.0 devices before you game on.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
