Ok, now on to the problem.
Starting a few months ago my system started to lag very randomly. Let me explain fully though before anyone jumps to conclusions and what I have tried to do to resolve it.
You can first notice the lag at the windows welcome screen, before your even logged Into Windows. The mouse cursor will skip around the screen. I’m using a Logitech MX500 that I have used through 3 custom built computers now. This is the first computer that I have which I have had this. I’ve already tried changing out mouse with still the same results.
Upon logging into windows, Once its Lagging - if you try to play a Game it will lag.(Game will Skip every 2 seconds) If you try to play a music file, the music will be choppy. If you even use the arrow keys to navigate the windows start menu, even then it will lag there as well. Basically once the system lags, it lags in EVERY respect, weather it’s playing a game, playing music or moving the cursor. Its very random and can go away for a week, and then plague me for several days straight. It also can just go away with a blink of an eye and not happen again for many hours. I can not think of anything hardware or software that changed when this problem first started to occur.
Now on to the things I have tried to do to resolve this.
I have run many adware/spyware scans. I have used Windows Defender, Ewido Security, Ad Aware, and probably many others I can’t think of right now.
I have run anti virus scans, using my Norton Internet Security 2006, also scanned using Ewido, Panda online scanner, Kapersky and so on. All scans weather they were Adware, Spyware or Antivirus have all shown clean. (in Safe Mode and Normal)
I have updated ALL drivers, Video, Mouse, Audio, Bios, Chipset.
I have Defragged the Hard Drives
I have used run Registry Fix Tools and fixed any registry keys needed
I have even gone through every Service that’s loaded and one by one, stopped them to see if one of the services was causing an issue.
I have checked the task manager and used process explorer to see anything running that shouldn’t be. The memory usage and PF usage are fine. (About 400 PF usage out of 2 GB of Ram) after full boot up.
Finally I have also Formatted the C Drive and still…the problem came back about a week after the format.
I’ve monitored the CPU and system temperature. CPU runs around 26C-29C and the System around 34C
I have Run Memory Testing tools with no errors reported
I have checked the CAS on both Ram sticks. They match.
I have run hard Drive sector checking tools with no bad sectors reported
I have physically taken out each stick of ram (there’s 2 of them) and used only one for a given time, then swapped them, and still the problem happened with both sticks of ram.
I’ve tried changing the voltage for the Ram of various variables with no luck.
I have tried changing out Mice and still the same problem happens, so it doesn’t appear to be related just to the mouse. That’s why the rest of the system lags as well, not just the cursor.
I am at a total loss on what could be going wrong. I done everything that I myself can think of, before posting. Can anyone help at least narrow down more what could be happening? It is possible that I may have left out some troubleshooting I have done because I’m trying to remember Everything I did try…but there could be more but I didn’t remember to post it. I’m really self conscience about my system and I don’t treat it poorly, I keep my security software up to date, I am careful with the hardware.
