CPU USAGE AT 100%

CPU USAGE AT 100% I have a Celeron 300 overclocked to 450. It has worked great for about a year. The last
3 times I have booted up, I havenoticed performance is suddenly alot slower. Looking at Norton Utilities,
PU usage is at 100%. And benchmarking
with Norton, my performance fell off by about 30%,
from where it was (about equal to a PII-450). Any
ideas what might be wrong???

Better check you cooling apparatus(FAN, heatsink, etc.) for
this CPU, when overclocking, you also need to OVERCOOL.

I have several fans in the case, and have checked it with motherboard monitor it's usually between 38 and 41 C, which is within acceptable ranges.  I don't think that would make it read 100%?? and why now after a year's use??

It would if the CPU FAN went out and the CELERON began to
overheat, but if you are sure of the 38 to 41 C and are certain
that this CPU temperature is correct, then check to see if
some program is constnatly using your CPU.

nah... the PIII's are actually a celeron 300 with a better heat sync and
more L2 cache... it is THE most popular over clocking chip on the market... chances are, you just have windows loaded down with anti-virus junk or too many performance testers... maybe you have alot of progs and games loaded and it just need ram... could be alot but it dosent sound like a hardware issue... gauranteed fix, get win98-SE (second edition) has tuns of bugs worked out, and lotsa ram..

I am only rejecting this answer at this point because it doesn't explain why, without adding any additional programs, the performance suddenly dropped...I have 192 meg PC100 ram, and when I check Norton, it says that it has about 40MB of that used, which is no greater it was before the performance drop.  I will try the Microsoft 98 SE, and if it does work I'll accept the answer with an excellent rating.

Thanks for the suggestion.....

right click on MY COMPUTER
and click PROPERTIES... click PERFORMANCE and FILE SYSTEM... change the typical role of this pc to NETWORK SERVER... that should make it more stable

I would remove programs one at a time that could be running.  One of them could be corrupted.  Are all your programs functioning as they were, just slower?

I changed the file system setting to network server, and the cpu is still at 100% usage at all times in windows.  This appears to affect all programs, which are still running, only running more slowly due to whatever is occupying the CPU.  

Thanks for all the suggestions though this is looking like a harder question than I thought

You should use a tool like Wintop to find out what program(s) are using how much cpu. on NT i has one built into task manager and you can get wintop (windows process monitor) as part of the  kernal toys for win95, I don't know about win98 though. I know tweakui has is on the win98, purhaps kernal toys is there too.

Also are you running anything like RC5/DES or SETI@HOME? These programs makes the cpu goto 100%.

Hey brainmaster you are the man

Wintop allowed me to pinpoint the program hogging the CPU..it turned out to be something in my quicken directory called Astro.   Reformat your comment into an answer and I'll give you your 200 points.

Thanks alot!!!!!!!!!!
