I have a Lenovo N100 system, came with 1GB, and after a long time of suffering, finally upgraded to 2GB. It really felt like the speed and the OS and performance are performing quicker and better, but this problem keeps returning:
In the middle of watching a video (not a really high resolution, your usual 350MB DivX file of 40 minute shows), or even listening to music, or none - just surfing the web, the computer starts lagging. I get the annoying circling blue thingy, which lags, starts stuttering - this goes on for about 20-30 seconds, and then computer returns to normal, more or less.
This happens whether computer was just booted, or after 20 hours of activity.
The only things that are running at the time are hardly uTorrent (not many downloads, mostly just one), messenger, Fireforx, AVG, and Diskeeper in the background.
Needless to say, the same phenomena occurred with 1GB of RAM, as with 2GB of RAM.
Tried turning off Diskeeper - no use.
Ran every hardware check - memory is fine, processor fine, hardrive with no errors, no fragmentation, tried deleting page file and putting back on again, ran every Anti-Virus and Malware scanners possible - nothing.
Ran Performance & Reliability monitor, when this happens, it shows:
What spikes at the minute this happens, is Memory - "Pages/Sec" - to 100
"% Processor Time" - to 100 - just as Pages/Sec reaches the max, the Processor time kicks in...
And also Processor "% User Time" - peaks, though to just about 50%.
Also a very small peak at ""%Disk Read Time" - but just to about 5.
This has started about a month ago, with no new software being installed. No drivers were installed when this started.
Any ideas what could cause the problem?

Shalom and welcome to the forum:
I will suggest you reformat your laptop by restoring it to factory setting, but only install the Lenovo softwares that you need, don't overload your computer with unnecessary softwares that you never use. Vista is laggy by nature, which is one reason why it will be phased out by Windows 7 next year fall.

Of course, formatting is an option.
However, it took me quite a few months until I actually got Vista to work properly, Wireless-wise, performance wise, and other things - as it was horrible to begin with.
Formatting is currently my last resort, would rather try some other things before that.

Okay, another option is to try this:
Open your windows task manager by pressing ctrl + alt + delete, then monitor the processes that cause spike, also copy and paste all your processes that you have running on the background, and lets see whether you have something that is unnecessary that we switch off or delete.

Well, the problem is, that the stutter prevents the system from working welll - until the Task manager comes up, everything calms down and I can't realize what was causing it.
I also tried turning off all non-microsoft services and programs on startup - still got the stutter.

Use Resource Monitor and create a Data Collector Set from counters in the current Performance Monitor display.
In the Event Viewer check the Diagnostics-Performance log for additional clues.

Since you can't catch the program or process which is responsible for mentioned problem,
there is only trial & error method left. There are numerous possible causes, so you have
to be patient and systematic...
The most usual suspects are antivirus and antispyware programs. To me there are two
of them known to freeze the computer for some short time without any visible causes.
First is NOD32 v.3.0 (read this discussion: http://tinyurl.com/5mo5nu)
Second is Spyware doctor from PC Tools.
My suggestion is that you completely uninstall any antivirus, antispyware and firewall
programs (except the internal firewall) that you installed and then give it a try.
