Har nå løst problemet, men det var ikke enkelt.
Jeg har XP Pro.
Dette gjorde jeg:
1, windows update -> men jeg var allerede updated...
2, oppdaterte norton, full virus scan -> fant ingen virus
3, msconfig, stoppet alle unødvendige programmer fra start-up -> hjalp i rundt 20 minutter...
4, kjørte Spybot (takk for tipset KK74) -> fant noen problemer, men pc'n var fortsatt like treg..
ble ganske oppgitt etter hvert, tenkte at det måtte være noe som "brukte" altfor mye RAM, gjorde litt research og fant ett program som heter CachemanXP, helt fantastisk!
Dette er sakset fra produsentens web site:
"CachemanXP is a system service designed to improve the performance of your computer by optimizing several caches, auto-recovering RAM and fine tuning a number of system settings. Auto-Optimization makes it suitable for novice and intermediate users yet it is also powerful and versatile enough for computer experts. Backups of settings ensure that all user modifications can be reversed with a single click. Due to the system service nature it requires Windows NT4/2000/2003 or XP to run, uses minimal resources and virtually no CPU time. The help file includes a screenshot based system performance guide.
RAM-Recovery
How does it work?
RAM-Recovery functionality is already included in Windows. You may ask yourself why there are so many programs that offer this feature. There is no magic behind this function. Inactive or crashed programs are simply moved from your physical memory (RAM) to a space on your Hard Drive called the Paging File (=Swap File).
If Windows does recover RAM already, why bother?
As an example imagine a computer with 512 MBytes of RAM. After booting up you have 300 MBytes free RAM left. You launch several applications, work with them and free RAM goes constantly down. After 3 hours there is only 10 MBytes of free memory left. Then you start loading a data file that needs 30 MBytes of RAM. Now the Windows recovery feature becomes active, programs that have not been used for a longer time are moved out to the Paging File in order to make room for 30 MBytes of data. This process consumes both CPU time and causes disk activity - it creates a slow down. Preferably you would like to work with the data immediately, not wait until Windows makes room for it. Instead your cursor becomes a hourglass and you have to wait.
What does CachemanXP differently?
CachemanXP will not wait with the recovery until your system runs completely out of RAM. You can configure at which state (below value) CachemanXP should perform the recovery process. The postpone recovery on high system activity option ensures that no recovery happens if you are working on an important task and do not want to be disturbed. CachemanXP will wait until the job is done and perform the recovery thereafter. Since the recovery happens earlier as usual your system will have free RAM left for a much longer time.
How does this CachemanXP feature differ from RAM-Recovery in other programs?
Almost all RAM-Recovery programs do more harm than good. Usually the recovery is done too often (constant disk activity), too much data gets moved to the Paging File (so when the user switches programs there are major slow downs) and often the recovery is executed in times where the user does something important and CPU consuming, slowing down all system operations.
CachemanXP ensures..
no recovery happens if the system has still a lot of free RAM left (below setting)
long pauses between recovery operations (pause setting)
the recovery will be postponed if CPU intensive applications (like video editing software or a fullscreen game) are working
active programs are not moved to the Paging File "

anyways, installerte Cacheman, etter det har laptop'n fungert bedre enn noen gang, den har aldrig varit så snabb! Uansett hvor mange prosesser jeg kjører samtidig går det smooth! Anbefales på det sterkeste.
Takk til alle som kom med tips!
