Hello everyone, this is my first post; I've never actually posted on a forum for help before but I can't find any resource on what this is or how to fix it.
I received a new computer around christmas time, and I've been using it up until now.
I'm not sure when this issue began to occur as it's a very subtle one to me.
(Especially since the only USB device I usually ever use is a mouse)
Anyway, my computer seems to be working improperly with any USB related things I connect.
Key point being that they WORK, just not properly.
I've tried formatting very recently and it still persists.
I first noticed it when playing Call of Duty 4 Multiplayer, as my perspective was jumping randomly when I tried to precisely aim.
It WAS almost unnoticable while turning/moving the mouse fast, but it seems to have gotten alot worse since then.
This issue is alot more noticable when using the mouse cursor on my desktop.
The cursor CLEARLY glitches when moving in any direction.
I've carefully drawn some lines on a BMP in MSPaint and saved the result.
In comparison, I've tried a cheap acer PS/2 optical mouse that came with this computer. This was the result.
My USB mouse is a Microsoft SideWinder. (not an X5/X8 model; just the original)
I have two of it; one on this computer and one on an older computer upstairs.
I've tried switching the mouses themselves, switching to other surfaces (wooden desktop, paper, my wall, the carpet, a table), and the results are either the same or worse on this computer, while flawless on the older one.
I've also tried switching between USB ports on the top, back, and the one on the front.
The only thing that has changed about my computer since I got it was that I purchased a Nvidia Geforce 9800GT (EVGA packaging) from NewEgg and installed it.
I note that the supplemental power-cord that came with it had two 1x4 plugs to be connected from the card to the PSU, but as the PSU only had one available, that's all I've used.
It has worked on all games I've tried up to this point, most with highest setting and still very playable results.
For example, Call of Duty 4 (especially MP) runs maxed out on 1280x960 with well over 120 FPS.
Before this card, I used an ATI Radeon X1600 Pro.
Also, the computer came with an ATI Radeon HD 3450.
I'm not sure if both plugs being used is necessary, or optional;
I've never been at a decent understanding of hardware.
Only software, so I had a friend of mine pick out this videocard based off of the computer specifications I gave him.
Also, this lack of hardware knowledge I have is why I've mentioned just about every detail, no matter how small, as I'm not sure what is capable of causing this issue.
Also, in my Device manager I notice that two things are not installed.
SM Bus Controller
Universal Serial Bus (USB) Controller - Read the next part before assuming
I've looked everywhere for drivers for these based on what PCWizard told me.
Notably though, on my old computer I was missing these as well, and the mice always and still do work properly on that one.
Also, I've never had them installed on this computer, and the mice used to work on it as well.
My main computer specifications are:
Mainboard : Acer RS740DVF
Chipset : AMD RS690/RS690M
Processor : AMD Athlon 64 X2 4800+ @ 2500 MHz
Physical Memory : 3072 MB (DDR2)
Video Card : NVIDIA GeForce 9800 GT
Hard Disk : WDC (640 GB)
Operating System :Microsoft Windows XP Professional 5.01.2600 Service Pack 3
I'll post up any other specifications needed upon request.
I have no idea what's causing this, but it's near impossible to play any FPS games anymore.
I USED to be able to outshoot many snipers in CoD4 with SMGs or pistols, but that is pretty much impossible now.
Anyway, if anyone could help me with this, or even point me in a certain direction, I would GREATLY appreciate it.
It really kills me that I finally have a decent PC as a gaming platform, I'm having such a difficult-to-pinpoint issue.
Also, PM me if I've misconcepted any of the rules.
I read them thoroughly, but just to be sure.
Thanks very much for reading!
