Problems:

I'm not quite sure, honestly. I feel like the HDD's read/write is slow when installing something on Steam, but when I'm just testing the disc's read/write on its own it seems normal. Then, when I'm playing League of Legends, random things in game will "jump" all over the place, even though they're just walking. Also, I get an issue when attempting to launch Kerbal Space Program, where if I install it, it works fine, but then if I restart, it crashes on startup. When I was installing CS:GO initially, I had a supposed "corruption issue" that forced me to reinstall. I've had this computer for a week and a half now.

Attempts to Diagnose:

Parkdale hard drive tester shows nominal read/write. Cinebench shows my CPU functions above average. I also got a 4-pin to 8-pin power connector for the CPU (see "additional details" for reason). This appeared to exacerbate the problem, so I removed it, which fixed it for about a week. Windows Memory Test finds no problems. I also reinstalled several of the games, which fixed the problem for CS:GO but not for Kerbal Space Program.

Additional Details:

This is possibly the cause, but again, I have no idea, and am looking to test. Anyways, the case comes with a non-modular power supply that only has a single 4-pin CPU power connector. The CPU appears to run nominally with only 4 plugged in, but I installed a splitter just in case (as I saw recommended on several Tom's Hardware forum posts).

I believe that the problem is either a) a bad HDD, b) poor power connections to the CPU, or c) poor power distribution as a result of the connection to the CPU. However, I am no expert, and I'd like to get to the root of the problem for sure before looking for replacement parts. Any solutions or tests would be very much appreciated. Thank you!

My money is on the HDD, but the PSU also stresses me out. I never trusted anything that isnt half decent. Those rosewill PSU's are sometimes not as efficient as they say they are. depending on whatever else you have hooked up there, you're probably using about 300w of power against that 400w. If the PSU is as cheaply built as I think it is, you're probably hitting its actual capacity. Again, I'm just really biased against cheap PSU's.
