Unfortunately, your screenshots don't reveal anything of particular interest.
Try going here and getting a copy of Process Explorer, unzip it, and run it. It has a column that will show the CPU utilization of every process on the computer. Note the ones that appear to be causing the issue, and right click them and select the Search Online entry. It will automatically use your default search provider to look up the process name.

 

kobby2k6,
Why do you have 5 instances of Chrome running?

i dont know, i just had one tab open which was for posting this question...do you think that's the issue??

p.s. i just opened google chrome with one website and it opened five processes again...i think that might be the issue...i also tried with internet explorer and it also opens five instances of internet explorer..what is going on ??

 

kobby2k6,
I don't think that your Chrome application is using all of the CPU. It looks like setup.ovr has >24%. That process is part of your Avast anti-virus program, so unless it has been hijacked by some malware, it's a valid job. Have you received any updates to Avast recently? It should not eat up so much CPU.

it seems to be fine now...battery life is back to normal (fingers crossed)
