Why does my computer so slow?

If you have a 768 mb ram and 256 mb graphics card, vista will run smooth and fine. Dont keep too many programs running at a time this could get you slower.

Switch back to Windows Xp then. It won't harm your computer. Vista requirements are higher. To run with a 1GB RAM is bare minimum I should say. You need at least 2GB to really have smooth performance. Plus if you have an on board graphics, that'll take part of your RAM power, so a dedicated graphics card will boost up your speed, the higher d graphic card memory the better. Reduce your tray items, the ones beside your clock, taht'll speed things up especially at start up. Too many things on your destop will also slow you down especially with unnecessary apps / widgets using Vista

Each time that Microsoft have released a new operating system it has required a greater amount of resources, such as processor power and RAM etcetera. Windows Vista needs far more resources to run than Windows XP, so you need a very good computer or you will certainly notice the difference in speed. If your motherboard will support it then you could upgrade the RAM and maybe the processor, otherwise it may be advisable to stick to using Windows XP. Windows Vista can be an excellent operating system, but it is of little benefit if your computer is struggling.

Yeah, i also noticed that, and this is the only reason that i quit vista and back again in windows xp. Its really amazing in working in windows xp rather than windows vista...lol
