Herky Jerky Mouse and Lovely CPU spikes

I've just recently upgraded, and now my mouse is really jerky. Not just the mouse, but its like the computer stutters. Like on Farcry it will be playing great, then it will "hang up" for a second, then go back to being fine. I've noticed that my cpu load with nothing open will spike as well. I will be moving my mouse across the screen, and it will all the sudden get "stuck" in a spot, then it goes back to being fine. I have all critical updates for XP, new drivers for VIA chipset, and new drivers for R9800 Pro. I installed XP on a fresh harddrive last night. Any advice would definately help! If you need me to describe the problem better , let me know that as well..
 
Could be the network causing the problem, is it always jerky? Have you checked it for the various worms that are going around?
 
Even during single-player gaming? No, it has not always been this way. I haven't checked for worms, but since I haven't downloaded anything but drivers from microsoft and ati, I figured that those probably didn't contain viruses. I did change the network card from autosense speed to a manual choice. That didn't seem to help.
 
Have you run Memtest86? I used to think Geil was a quality brand, but it seems to have developed a reputation of instability (though that does seem mostly on nForce 2 boards - not sure about the Athlon64 boards).

Of course if you have any extra ram lying around, switching it in to see if the problem persists is much faster than Memtest.

Edit: What brand (and specs if possible) is the PSU?
 
"I haven't checked for worms, but since I haven't downloaded anything but drivers from microsoft and ati, I figured that those probably didn't contain viruses"

The worms aren't "downloaded", within 15 minutes of hooking up a new PC to the net you can have it.
 
I don't, I just ran a scan. My point was that the install was fresh, and therefore it should be a lot less probable that I would have a virus or a worm compared to if I was running a 4 year old install. It's supposed to be 300W Allied PSU. I only have one HD and one CD-Rom connected on my computer.
 
Actually, that is where you are wrong. A new install is far more likely to get infected with the worm. They take advantage of unpacthed system immediately, like a system with a fresh install. It is also very unlikely that a power supply would cause "jerkiness". Lockups, crashes, shutdowns, yes. Slowness, not likely. You can try by removing any unnecessary components (like the cdrom, usb devices) and see if it works any better. Also, check to make sure DMA is enabled on all your drives.
 
Thanks for the info on worms. Now it seems that even typing the computer is studdering. I'll be typing and the text will like hesitate. I'll check what you said.

-Updated BIOS
-Used a different ram module
-Checked for heat problems by putting a box fan blowing air into the case
 
Let us know how it goes, definetly sounds like you might have caught the recent sasser worm as your computer is exhibiting similar behavior to infected systems.
 
Microsoft on-line site check says I'm not infected, so does symatics on-line check. Any more ideas? DMA is enabled on my drives.
 
I said it wasn't just the mouse at first, but now I can say that it does the same thing during video and audio. Audio is basically unlistenable because of all the breakups in it. It just like stutters a lot. Any more ideas, this is really starting to make me angry.

Memtest86 won't run, it says "loading..." then the screen flashes, and then the computer reboots. I replaced the ram with another stick and the problem continues to persist.

-Updated BIOS
-Swapped ram modules
-Checked for heat problems by having a fan blow cool air into the case
-Reinstalled WinXP, got "the procedure entry point Getimus could not be loaded in the dynamic link library msdart.dll. I had to restart setup. This reminded me that I believe the same error (or at least an error) occured during the first install of XP. Upon further research it seems this error is sometimes caused by the blaster worm. I downloaded Symantec's removal tool for this, and I was not found to be infected.
-Tried an ancient PCI video card(Problem still happened, but not as frequently)
-Unplugged everything that is not absolutely necessary (Mobo,Cpu,Vid card, and HD only things w/power)
-Tried two different harddrives
-Tried different HD cables
-Tried plugging computer into a different wall outlet(one with a surge protector, for all that matters)
-Got an Antec 430Watt TruePower PSU
 
I would definitely suggest trying a different power supply. Many of the worms change names of files, making it difficult to detect. Perhaps you should try another format and leave the network card disconnected. If it works like that you know where your problem is.
 
Got an Antec Truepower 430watt PSU. The problem still happens. This PSU, from what I read, should be more than adequete. I've noticed that the computer hangs before post (where it runs down your processor specs and stuff, righ?) Like it will hang on the MSI screen for awhile, and then finally go into post. Another thing, I don't knwo if it has any effect at all, but my drives read g, h and i. Wouldn't one think it should be c, d and e? Or does this depend on something I don't know about?

Ok, tried fresh XP install. Worked great, until I installed the mobo drivers (on-board sound, network card, etc). Now I couldn't really get a good test (I usually play a cd to test for stuttering, but since there is no audio drivers, I couldn't), but I think *maybe* the problem lies in one of those drivers. I have seperate sound and network cards I could try, that would maybe eliminate the problem. Any opinions on this? I still don't think its a worm because the internet was disconnected the whole time the above stuff was taking place.
 
I think I finally managed to fix the problem, thanks for all your suggestions. I believe the problem was either the onboard audio or NIC, once those drivers were installed, the problem came. Once they were removed the problem ended. However, I still have about 5 devices with yellow warnings in device manager, but I don't want to mess with them for fear of the problem reoccurring. Can I safely delete those off the device manager?

Also, will the fact that I have not installed any of the motherboard drivers noticably affect my gaming performance? (Inc. VIA chipset drivers, but I *think* I could safely install those)
 
Just make a system restore point before you start fooling. If things go bad you can just roll back. No worries.

If it has a yellow dot in device manager then it's not running for some reason or another. Yes you can safely delete it. However, it's just going to redetect at boot and unless you supply a driver it will yellow dot again.

I would recommend downloading the latest drivers for everything, deleting the yellow dots, rebooting and pointing everything to the right place as it comes up. Definately update your mobo drivers.
 
What I'm telling you is when I DO update my mobo drivers then all my problems start... That is why I didn't in the first place.
 
Knowing that it may cause issues you can proceed with caution.

However you still need to get your drivers updated.
