Computer CPU usage 100% anytime a program is opened and slowsdown
For the last couple of months computer has been showing that the CPU is using 100% of the resources whenever any program is opened. If more that one program is opened at once, computer slows to a crawl or freezes. Thought it was a virus but have restored system to original state. CPU usage jumps up and down constantly when idle. Don't know if RAM is to blame or CPU and motherboard. Have received NO OPERATING SYSTEM FOUND message when restarting computer from hibernation state. Also blue screen came up once before computer restarted. Don't know if there is a way to test system to find problem. Any suggestions?

In Task Manager, go to the Processes tab and sort by the CPU column. See what is hogging up all your CPU. It may be a virus, if so, I recommend downloading Malware Bytes and doing a full scan. Warning, it could take several hours to scan depending on the size of your machine. Good luck!
This is due to memory and program usage.
Depending on your computers specs. try these steps
1. Disk clean and defrag
2. Virus, spyware, malware, Trojan, rocket scan and removal
3. Registry cleaner and optimizer
4. Check disc space on the C: drive
5. Turn off unnessasery programs auto starting
If this does not work it maybe that you need to upgrade your computer or add some extra RAM.
It sounds like there could be a virus on your computer that is using up all of your CPU resources. Try to monitor the processes and CPU usage, buy pushing Ctrl + Alt + Del at the same time. This will open up the Task Manager on XP, or show you a menu screen on Windows Vista and 7, and you can click on start task manager at the bottom. View all your processes and how much cpu usage is being taken up from those processes. Look for the process using the highest cpu usage when it spikes to 100% and please repost the process name!
In the mean time might I suggest running and anti-virus scan, scanning for malware, and spyware as well. If you do not have any of these programs, I would suggest using either AVG, or Avira Anti-Virus, Malwarebytes, and Super Anti-Spyware, all of which are free programs that can be downloaded here!

Be careful how you interpret this information. In general, any program that has "work" to do will use the CPU when it is available. Showing 100% CPU usage over en extended period of time MAY indicate a problem or it may just reflect the case where there are background programs beiung run that have no effect on the system. The "scheduling" iof the CPU is usually done in chunks called quanta. Since CPU time is usually scheduled on what is called a pre-emptive mode, lower priority jobs (like virus scanning of the disc) will be pre-empted by an interactive user command (word processing for example).
Without examining your system and understanding what programs are running, it is hard to provide guidance on how to "fix": the system. Use the task manager to see what percentage of time is being used and for what. The utilization is shown as a percentage of the whole. Report the info here and we should be able to at least explain what is happening.
Try to monitor the CPU usage before opening CROME. If it is normal before opening it then there is some process under CROME which takes you CPU usage report to GOOGLE on this. and remove it through Add/Remove programmes under control panel.
Try to use Firefox instead of CROME.
If it happens again then there is some thing wrong with OS( most probabaly Spyware or trozen).
this is an all too common problem with windows services host, but you will have to refer to this site as there are a few things you can try
