A stab in the dark i know but looking for some reason as to why the CPU would be running a lot slower than it meant to be?

Its my mom's PC n not 100% sure where she got it from is it's 2nd hand but she has had it from some time. Not got the PC in front of me but going to reformat it for her in the next day or so. So just looking for any ideas of how i can get the CPU running as it should be.

Mother board is PC chip P21G.

She really dont have any spare £'s so im wondering if it would be worth getting a P4 2.6ghz+ of the bay to put in there, as the system dose seam to go slow from time to time. Would the P4 make much difference over a celeron D or would it be better with increasing the memory in there?
 
Intel speedstep is probably running which reduces the clockspeed when it's idle to reduce power consumption and heat. You can disable it in the BIOS.
 
2.3 or closer to 2.4Ghz? I think its 24x133 for 3.2 so its probably running at 24x100 for some reason, BIOS will have to be set. Might get a decent dual core in that board? No idea on the cel d is it LGA775? Board likely will not support core 2 but has a better chance with a dual core 9xx series PIV.

AFAIK that cpu does not have speedstep.

It is closer to 2.4Ghz, if i remember right when i was there a couple of weeks ago taking a look at it. It was running 2.39Ghz. If its the settings you say it is. Will it be ok just to change them or would i run the risk of making things not work? An would there be some reason why someone has under clocked the cpu? Cos the last thing i want to do is ruin the PC, yeah crap spec but my mom really enjoys playing Mahjongg & surfing the net etc

Well, being brutally honest PChips motherboards can be utter crap, prolly cheapest of the cheap. The system may have been unstable at stock speed (seen this with that brand a fair bit in the past, however i have no experience with pcchips in the last decade). Only way is to up the FSB and see if 133Mhz (533FSB) works. Could be a simple case of the system builder knowing nothing about pcs and leaving it at first boot value, safe values loading for some reason, or like you said there might be more sinister reason.

IF i up the FSB & things dont work, would i be able to lower them again or would i run the risk of killing the CPU if i increase it? If there is a risk to the CPU i think i might take the view that its not meant to be run at full speed for some reason.

Its got me thinking now if i go & get her a cheap CPU to put in there to help speed it up abit using the same motherboard would i run the same risk that it might not be able to run that CPU at the full speed it should be able to

Just reset bios via jumper. Can't kill the cpu like that either it just won't boot.
 
Ok, il give that a go when im there tomorrow. Il post back then & hope fully wont have to many problems with it.

Thanks for you help
