Hey there. I'm having trouble on my laptop. Recently I fixed up an old laptop and everything, seems to be ok apart from one thing, and that's my CPU usage. It's spiking through the roof from 10% - 70%+ nearly every 20 seconds. This seems to be directly related my my FPS drop when playing games like League of Legends and I can't find out why it is happening. I've checked my performance tab and resource manager, and nothing seems to be causing it, I seriously can't see anything that suddenly uses everything.

I have ran a boot time scan with avast which did pick up some things, but they were all moved to the chest.

Another factor which may be useful is the way I fixed my laptop. The HDD completely failed beyond recovery. So I scavenged from an older laptop which I don't use anymore and took that Hard drive. I had to do a bunch of updates etc but that all seems done.

Any suggestions?
 
Sorry I used the wrong term. I meant disc as in a CD. I don't have one at the moment and I have no blank CD's I can burn to at the moment either.

I came across this in my event viewer, I thought it'd help as (The speed of processor 0 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 38 seconds since the last report.)
 
Actually you will need a dvd to burn a W7 image.

Here is the deal: load your BIOS and roll back to the default settings, so we undo any manual set up. Also, check at Acer/ASUS (I don't remember what laptop you are using now) if there is any update for your BIOS.
 
You can always install a Linux distro for free, or buy a windows 8.1 OEM license. They're like $99 on Amazon.

You can download windows from Microsoft and try it free for 30 days before requiring activation. If you just want to see if the system will work reliably.
