SUDDEN SYSTEM SLOWDOWN(win XP sp3)

Hi RJARRRPCGP,

I am not sure about how I can use this to approach my problem. You sound very technical. Can you please explain.

Hi RJARRRPCGP,

Intel processors, at least since Pentium 4, self-underclock if the temp is measured to be past roughly 85 C on the processor.

Hi Andre,

This is almost one year since I reported the system freeze/slowdown and subsequently with your help figured it out as ACPI issue. You suggested "your processor P4 must have gotten slow" & suggested changing the Processor could be a solution. I tried another P4 with out desired results. Then the thought about ACPI drivers stuck me. Through the device manager I changed the ACPI driver from 'ACPI uni Processor PC' to 'ACPI Standard PC'. to my surprise the pc behaves like gem. It is very fast now and boots in 25 secs. It is now almost one month without the problem.

The only change i noticed is while shutting down as it used to be some years back the PC comes to the screen "now it is safe to switch off your computer" instead of shutting down completely. I have to power off.

I belive this could be an useful tip to others as well.

Thanks for helping to trace the problem.

ok, thanks for the feedback.

@ganesh61: You can try this old trick for shutdown. Worked for me a looooong time ago when I changed HALs...

edit (clarify): You need to install manually NT Apm/Legacy Interface Node (step 5).

Hi,

I am new to this forum. I am not a Techie. I saw MAGIC ANDRE's Dec 2009 response to 'How to get the cause of high CPU usage by DPC / Interrupt'. I think he can help me to get rid off this maddening experience of my system slow down. It logs in with in 70secs and maintains a very decent speed in its operations. But during the course of an application or even when it is idle the CPU usage climbs to 100% and the sys starts crawling. becomes dead slow that makes you go mad. Media files cannot be played, if you try you get outlandish noise from the speakers and never recovers till you restart the sys.

I am not able to identify the process which evokes such reponse from the system becz it may happen at any time. It may not happen at all on a given day. Now I have been working with it for the last 40mts with out this nusense but after restarting it for four times prior to that in an hour of work.

I have tried everything, through scanning by antivirus, malware, etc system is clean. I have registry cleaner(uniblue) and system speedup(amigo) tools with no help.

Process explorer indicates an idle process of 90%(when no application is running) when the system is alright but in the slow down state idle process is either 00 or upto 10%. However 'hardware interrupt' in PE jumps to even 50% once the system slows down. When the system is normal it would be < 1.5%

the specifc of my system:

Processor: Pen 4, 2.26gh

Hard disk : 2 nos. 80Gb and 160 Gb with operating system in system-partition of one of these disks. there a 6 partitions.

RAM: 1 GB DDR1

OS: Windows XP SP 3

I have formatted all the disks since i started getting this problem with out any result.

I know vry little abt computers, but i have taken this as a challange. Every day I am spending a lot of time visiting a lot of web sites and trying every possible trick to set this right. When the machine behaves you love to work with it.

Would appreciate help from any member of this forum.

Most likely you're dealing with a failing or failed piece of hardware or overheating. You should take it to a local PC shop since you don't know what you're doing and could do more harm than good. Ask them to check if the CPU heat sink is properly installed and to try another PSU.
