Can a corrupted/incomplete OS hurt your CPU performance?

I play FFXIV which is more based on CPU than GPU and my frames took a dramatic drop. I went from 130fps to 40fps. I've bought a new PSU and that wasn't it. I've tried my GPU in a friends PC and it worked perfect. Reseated the GPU in a different PCI slot still the same! I've never Overclocked and my temps are normal. CPU stays at a constant 42c to 46c. Only thing I haven't done yet is re-installed the OS.

Specs

Asrock Z97 Pro-4
i5-4690K
Samsung 850 Pro 500gb
WD Green 1.5tb
Asus Strix 980
Corsair AX760i
Windows 7 64bit Professional

The CPU runs at full speed? Unless you use an extreme cooling solution, the temperature would lead me to believe that it doesn't. Use Intel XTU to check it.

Corrupted files don't hurt your CPU, but they can hurt your performance by quite a lot. I am not entirely sure your problem is related to corrupted files. Does it blue screen or boot very slowly? Have you noticed it acting strangely, like crashing programs randomly? Run something like Malware Bytes to check it for malware or viruses. You could also run Ccleaner if you wanted to. Start with MBAM before you do any thing else.

No it doesn't blue screen nor boot slowly. Everything boots just fine. I have had recent crashes though as in when i try to play games, it freezes and i have to hard reset. I have Malware Bytes running but no threats. I can try CCleaner and see what happens from there. Also I tried to run Prime95 and i got an error if that helps with anything.

This is the benchmarking I did using the Intel XTU
http://puu.sh/jdxlG/66650cb246.png

Major thing I can see is that my frequency isn't up to par. It is at 800MHz while I look at others they are at 3,900MHz and up when I analyzed it and compared it with others.

Don't know if this could help but I think anything is helpful atm!

Intel Core i5-4690K CPU @ 800.0MHz - 209 XTU marks on HWBOT

I would look at the bios and try doing a bios reset. Shut the pc down, turn off the power supply and unplug it and remove the cmos battery (flat round coin cell near the top of the blue pch heatsink, may be partially behind the gpu) for a few seconds. Put the battery back in and plug the power supply back in and restart the computer. You'll have to reset the date and things in the bios but it will set it back to factory defaults. For some reason it has your cpu stuck at 800mhz and that's what's killing your performance. It should go up to 3.7-3.9ghz (if not overclocked).

It should run at full speed when using the easy CPU stress test in XTU. Run the stress test test and then provide a screen print of XTU results. You didn't mention if it throttles or not, but since the temperature is normal, then it probably is a setting in the BIOS or the OS that prevents it from running faster.

I did it and it did reset but my cpu is still stuck at 800mhz.

Here's the screen print of the stress test.

I didn't throttle at all that i seen. No thermal, power limit, or current limit throttle at all.

When i was under the XTU and were looking at other benchmarks, i noticed you could download their settings. Do you think i could download someone else settings that didn't OC and see if that would do the trick.

It's obvious the processor frequency is stuck at 800 MHz. You should reset the CMOS settings to the default values; if that doesn't help, then make sure there isn't a switch or a jumper on the motherboard that could cause that issue. If nothing fixes it, then contact ASRock to RMA the motherboard.

I followed through with doing that and it still kind of didn't help but I went with a gut feeling and redid the XTU benchmark test and found someone using the same Mobo and CPU as I am. I downloaded their settings of their CPU and added them in to my computer. What do you know that did the trick. What was wrong was that my core 3 and 4 were down-clocked and I'm guessing made a big difference in the frequency speed. Thanks for your help cause without it I wouldn't have found any of this. I did also notice that my Temps now match what they were giving in my BIOS at a constant 52C.
