My computer is several years old now, but it's always functioned well as far as gaming's concerned. I've had little FPS slowdown with any of the latest games, and before this issue set in, could easily play games like Skyrim, DMC, and ACIII on the highest settings. But about a week ago, everything just changed without warning. I bought a GTX 660 to replace my 550 TI in response, along with a couple extra gigs of RAM, but this has done nothing to solve the problem. I'm becoming increasingly frustrated, and am VERY close to just giving up and restoring the computer to factory settings.
Things I'm PRETTY sure it's not:
Core Temp reports Core and GPU temps of no higher than 40-45C, averaging at around 36.
Installed the new 320.18 nVidia drivers a couple days ago, then reinstalled them; if anything, it's exacerbated the problem.
I'm running a couple full system scans tonight, but a quick scan from both Malwarebytes and MSE has turned up nothing (well, 42 instances of malware, but nothing that apparently affected my computer's performance).
I defragged the thing, cleared out the registry, uninstalled every spacehogging program, and updated everything outdated I could find, but nothing has helped at all. Please help me.
CPU: AMD Athlon II X4 620 Processor 2.6 GHz
RAM: 8 GB DDR2
GPU: nVidia GeForce GTX 660
MBoard: ASUSTek M3N78-VM
Two 500GB Hard Drives
Could find more out about the PSU and HD if necessary.
In League of Legends I used to run 40-60 FPS on my old Graphics card, on highest settings (550 Ti). I now average 15-20 FPS on the lowest settings in teamfights. Highest settings yield around 4-5 FPS.
Is there any test/easy way to tell if my hard drive is failing? It wouldn't surprise me (my second hard drive is by far the oldest part of my system), but I'd like to be sure before shelling out more money for hardware.
