Step 1:
Hangs When Idle for a Long b> Normally your computer will turn on a screen saver or enter sleep mode after a certain period of idle time, to protect your monitor from suffering a "burn in" of an image that appears on the screen for extended periods of time. This also helps to save electricity during periods of inactivity. Vista owners report via Internet tech help forums a seemingly rampant "bug" that causes the machine to freeze after being left idle for long periods. No single factor seems to cause this, and instead requires troubleshooting and trial and error to find a fix that works.

Screen Saver Failure
When your computer freezes after a long idle period, it could be due to a malfunctioning screen saver. Turn your screen saver off, by clicking "Start" and then "Control Panel." Under "Appearance and Personalization," click "Personalization" and select "Screen Saver." Select "None" under the screensaver drop-down list and hit OK. Pay attention next time your computer goes idle for reappearance of the problem. b> Power Saving Options b> Windows Vista provides users a way to select how their computers behave after sitting idle for a certain amount of time. In many cases, the hard drive and monitor are instructed to enter sleep mode or even shut down after they've been idle for a specified time frame. To check or alter your settings, click the "Start" button and then "Control Panel." Under the System and Maintenance icon, click "Power Options." Under this tab you can change the amount of time before your system goes to sleep, and the actions it takes after reaching the idle time. Malware b> When mysterious things begin happening to your computer for no apparent reason, there's a good chance a malware program is behind it. Malware are nasty, hidden programs that download themselves onto your computer to cause havoc and even steal your personal information. These invaders monopolize your CPU, clog your RAM, and generally make using your computer unpleasantly slow and frustrating. Their presence can affect everything from program operation to operating system functionality. Always update and run malware protection software regularly to keep these pests out of your computer. b> Update Windows and BIOS b> Your computer's operating system and BIOS files are responsible for proper operation and functionality. Over time, these files can become outdated, requiring patches, fixes and other updates to correct compatibility and security problems in your computer. Microsoft provides regular updates for its Vista operating system to correct reported problems. The BIOS in your computer is programmed into the motherboard, so the board's manufacturer may have an update available for your version. In many cases, the brand that sells the computer may offer a link to the BIOS update, so check with Microsoft for any updates available. b> Too Many Processes b> Your computer will register as "idle" if you haven't used it, even if you have programs open on the screen. After a certain amount of time, the system will send the data you were working on to the RAM as the system settles into sleep mode. When trying to wake the system after this idle period, it may have a hard time resuming the programs that are open, causing a freeze. Close down any program you are not actively working in to save the CPU from unnecessary work, and lessen the load placed on the RAM when it's left idle. right mouse click in the bottom toolbar select task manager applications if you see something running that should not be running select end now you might even uninstall that specific program if its no longer needed also in the processes tab see whats ticking over in the background might be a virus or malware.

System Idle is unused CPU cycles, represented by the dark portion of the CPU graph/taskmanager icon. Hard to reconcile your saying CPU usage is 90% in Taskmanager when taskmanager is reporting 87% system idle at the same time. Enabling "show processes from all users" will unhide some running processes but it still shouldn't contradict that 87% unused CPU cycles. On the taskmanager Performance tab is show "one graph PER CPU" enabled?
What was changed in your system between the time these symptoms started and the last time it behaved normally? Did you try a System Restore to a point when it did behave normally?
Are your CPU core temperatures normal or high? Is CPU stepping reducing the core speeds, possibly because of power saving or overheating issues?

Hi brother
I will suggest you some way to increase your speed of the PC assuming that your system is booting up normally and after loading OS only it is showing slowness
1) Please START then RUN then type msconfig and press ENTER. Click on the Startup tab and uncheck any program that you do not need to start when the system starts. See if that helping you.
2) If that is not working check with Task Manager see how much of the installed memory is being used (PF Usage). You will probably see it higher . In the process tabs with no Applications running your system idle process should me around 98%. If it is not, I would suggest that you run your antivirus and spyware programs (besure they are up to date).
3) Open my Computer>right click on the C: drive>Tools tab. Run both test in this window. (scandisk and disk defragment)
other wise check with service center for any comparability issues
please support me brother Take care!

Hi,
Do you have any antivirus program installed? If you have, check if it set to scan during startup. This might be the reason why your computer is slow during startup since a full computer scan can definitely eat up memory usage.
Hope this helps.

hi if you can check this website out it shows how to stop unwanted processes on your vista system, this has helped me in the past and speedsa vista up to xp standards. if it is being used in a work enviroment you will need some of the processes and this should be done one at a time and tested on what you would normally do. also if you check your anti spam and antivirus for bots and such that sit idle till needed but take up vital processing power. hope this helps?

I think this is the normal state. If any other program is running high a lot of the time, you then have to investigate that. System Idle means just that. Everything is alright.

System idle process is when a program has not been used in a while, so the computer leaves it idle until used or needed again.
There is definatly a issue with some program on your computer sucking up resources from the processor try a disk cleanup and defrag the drive, you could also go to my computer c:drive, and open the windows directory, find a folder named prefetch open the folder, highlight everything in the folder and hold down shift and press delete.

Open a command propt and type chkdsk c:/f and press enter, youll be asked if you want to set it up to run the next time you boot the computer type 'Y' for yes. Exit the command prompt and restart your computer, dont do or touch the computer until its booted up. Post back and tell me if you solved the problem.

Double check your system configuration and make sure you have properly identified the HDD to the system. Your initial problem may in fact have been bad clusters on your HDD but "fdisk" is a built in dos function. I would uninstall what ever software that you may think is identifying your problem and double check your virtual memory settings and then run HP Healthcheck WHILE you have anti-virus running. Aside from deleting cookies and making sure you don't have system processes running that you don't need you can look at increasing ram and fine tuning system resources.

System resources at 75% on idle only gives you 25% to work your notebook. Sony VAIO PCG-K25 Laptop 2.8 GHz Pentium 4, 512 MB RAM should be plenty to run most OS and programs. The OS, software and accessories attached to your laptop are utilizing 75% of your resources on startup. You may want to do some maintenance, check your processes on startup & carefully remove any not being used, check your networking usage, good antivirus & spyware cleaning, clean & defrag your hard drive, remove some of your files & programs,and upgrade your memory.
