PC mouse lag and overclock issues

[Mooni]

Hello, I got 2 problems that might be connected, I don't know.


The First problem that is driving me to insanity by the way is some sort of mouse lag or skipping when playing games and opening some programs. To me it seems to be some sort of bottleneck-like behaviour so maybe its just poor performance?
Hopefully visible:

Continuing on the first problem, when I somehow had changed the window power plan to "Power saver" instead of "High performance" by mistake, this problem happened somewhat random every 10-30 seconds and was more of a slow down rather then the skipping I experience now. And it seemed to be triggered by input ex dragging the scroll bar and not just moving the mouse.
This also was with my previous mouse (razer mamba) that was probably close to dying for good since it had randomly stopped twice that week (so i had to plug it out and in again).

Alright on to the next problem, I cant overclock my CPU.
I have tried to overlock to 4.2GHz (would definitely want to go higher but this was my first test) since it seems stable at the stock 3.8GHz with 4.2GHz Turbo and it seems to be on 4.2 all the time anyway but when I do my pc just freeze during any high load (prime95/games).
Tried disabling all C-States, EIST and internal graphics.
Also the freezing don't seem to be due to overheating as the CPU just hits 60C according to both "Core Temp" and "HWMonitor".

And when googling for solutions I found that freezing was often caused by faulty RAM and that memtest86 was a good way to test it so I ran that (took 4hours and 15min) and got 0 errors.

I don't know much about drivers and I might have screwed up, since I still had problems after installing them manually I tried 2 free programs to fix it for me. First "Driver Booster" from IObit and secondly "SnailDriver 2 Lite". Hopefully I haven't made things worse with this but as with everything please tell me if you need more information about anything.

For the first problem, when I see a mouse lag, start/stop, it tells me that something between the mouse and the OS is having trouble. Since you have tried two different mice, I would look at the port that you are using for the mouse. Look at your MB manual to see if they have a preffered port to use. If not, don't use a USB3 port as they tend to use a seperate chip aside from the north bridge. Fianlly, update the BIOS and drivers on your MB to see if there is a problem there.

I have tried a 3.0, 3.1 & regular usb 2 port and it dident make a difference and I have the latest BIOS.


Also yesterday I "reinstalled" my cpu/cpucooler and the freezing during load changed to crashing so I emailed the place where I bought the cpu and mobo about my warrenty, they havent replied yet (think they ha a 48h reply policy) but I can only see it being a hardware issue at this point.

It is possible that one of the two HDD's that you have listed is failing. If the computer dedicates itself trying to read a bad sector, it could have the symptom that you mention.

I tried disconnecting both HDD's and the CD drive but no difference. Also i forgot to say the reason I "reinstalled" my cpu was becouse it froze without any overclock after about 1-2hours of gaming without any alarming temps and now after the reinstall it crashes (turns off) 1-10min after starting the game every time at default bios settings.
