Windows 7: Computer slowdown - not severe

25 Mar 2011   #11

Win 7 Home Premium 64-bit

Like you said, turning DWM.exe off didn't help at all!

Here's a screenshot of resource monitor. Arranged in descending CPU usage. System Interrupt is among the top 4 always. But still, it doesn't seem to be taking up much of the CPU usage!

According to McGraw Hill Science and Technology Dictionary.
"System Interrupt Handler:
A section of a computer program or of the operating system that takes control when an interrupt is received and performs the operations required to service the interrupt."

I'll see if repairing Windows will help!

Thanks JohnnyA

From reading lots of threads relating to System Interupts, most folks are complaining about them taking 10, 20 60 even 100% of their cpu at times. Now that woild be a problem. Your screen shot is showing about 2% for this item so I can't see that as an issue. One thing that does confuses me is you said that Media files ran from main hard drive skip/pixelate, but run smoothly when ran from external HD. ??????
How did you make out with your planned Windows repair?

By the way, while it is on my mind, did you burn a set of Factory System Recovery dvd's when you got your Dell Laptop? Also a Windows Repair CD from within Windows. Start, Control Panel, Backup and Restore, Create a System Repair Disc. You may need one or both of these safety nets in the future.

Here's a quote from a Microsoft Technet FAQ, concerning missed scheduled tasks that run shortly after startup:

What about if the computer is off when it is supposed to be defragmented? When will the next defrag take place?

Disk Defragmenter will run when the computer comes back up for the first time after the missed scheduled task. The tasks scheduler team has implemented some nice safeguards to limit the impact of such “missed” tasks on system performance. More specifically, execution of such tasks will be delayed by a few minutes so that they do not interfere with a computer booting up or resuming from hibernate/sleep. In addition, such tasks are serialized and occur one at a time.

At this point, people are typically scared that defrag will run when there is an interactive user on the system and make the machine unusable. This was definitely the case in Windows XP and Windows Server 2003, but Windows Vista defrag uses low-priority I/O and low priority CPU, which limit the impact defragmentation has on user activity.
The same situation no doubt pertains to Windows 7, where housekeeping functions - like background defragmentation in this case, but also tasks like checking for automatic updates, compressing unused files etc., start some little time after the next startup.

Although designed to minimize interference with performance, such operations obviously may use processor, memory, disk and network resources, and show some impact on foreground application performance.

I do have a recovery media DVD, thankfuly!!
I finally figured it out, I have a faulty drive, bad sectors and all that $#!%
I restored my computer to an earlier Full system backup (a month and a half back). But things were still the same, if not slower!! Right then I realized this is definitely not a software problem, it has to be hardware. And from the fact that media files on my internal HDD tend to skip and pixelate, but not my external drive. I focused on the hard drive..... and on the second test run I see the magical word: FAIL ERROR 0F00: 1344
It was simple, but I wonder why it wasn't detected before!! I mean I was going about my normal day, with my laptop under my arm, running tests, but only on the third test did it give me an error.
Anyways, its still in warranty, and I called up the service centre and am taking it today.
Thanks a lot JohnnyA.

Way to go AB. Not exactly the best news but you nailed down the problem and are on your way to getting it resolved. Good for you for making those Restore disc's. It's amazing how many people don't know about/get around to this until it is too late. Been good working with you and don't be a stranger here at the Forum - lots of good advice and Tutorials.
Best regards
