Programs using extra CPU/100% CPU usage

Hello, a friend of mine recently went back to using their laptop after their main computer died (Doesn't receive power, getting it fixed soonish possibly). Their laptop uses Vista, and they used to mainly use the laptop around 1 year ago. Since then, their parents sometimes use it to watch videos/movies, but that's about it.

The issue they are encountering is, after about 15 minutes of being turned on, the CPU usage shoots up to 90-100%, even while idle. This makes the computer, and anything she is running, start to stutter/freeze. This goes on indefinitely (tested over night, so at least 10+ hours). The laptop has 3 gigs of ram, and has played much more graphically intense/system heavy things before with minor to no stuttering/lag. We have both tried looking up possible fixes (listed below) but so far, nothing has helped.

  • Running multiple virus scans
  • Cleaning the registry (CCleaner)
  • Scanning for virus' while in safe mode
  • Installing updates (a good years worth)
  • Installing Service Pack 2

I've seen plenty of people asking about SVhost causing the issue, but SVhost runs at low/normal CPU usage during all of this. The main programs that shoot up at Skype, and a game we are playing (tried with multiple games, and we've tried with just one or the other). While idle, the CPU usage states that it's around 75-100%, but nothing on the process list shows that it's consuming all the of the CPU.

Just to compare to make sure it was the game/skype, I compared her usage to mine. During the first 5 minutes or so, the game was about 3-10%, only going up to 10% when we were actively playing. Then when the stuttering started, the game slowly worked its way up from 10, and evened out around 40-50% while idle on the game. Skype would shoot up to around 30-40% as well, with the rest of the programs running normally and taking up a grand total of around 10%

Any help possible would be very much appreciated, but if you want to suggest to do a System Restore, it's not currently possible (Their parents don't want to lose whatever they have on the laptop, apparently).

Thank you for your time.

Try using 'clean startup' procedure to find if a service is conflicting. Just remember to Hide All Microsoft Services when trying out.

Yes, everything else just raises slightly to take up the CPU that was freed up from disabling it.
