I have a new computer with the following specs: Intel P4, 3.4GHz 925XCV chipset, 2GB DDR2 RAM, 500GB HD (RAID 0 and one backup - 3 total), dual monitor, Win XP SP2.
I installed the ATI TV Wonder Pro tv tuner PCI card and was experiencing high CPU usage. I discovered some other programs running using way too much CPU power, so i stopped them from starting up. now the CPU hovers around 5% give or take when i'm not doing anything but watching the CPU usage graph in windows task manager - where it should be.
HOWEVER, i'm still doing nothing and the CPU has a spike to 80% or so about every minute or two, I have no idea why. I had problems with the ATI card (still do - but i think it's becuase of the CPU spike) and updated the drivers on my realtek audio card and all the ATI software.
i've looked at all the processes and nothing is taking much CPU power. why would this happen? i have no idea what to do or where to start to look for the issue, but i'm pretty sure it shouldn't be doing that.
Please help. Thanks.
