help please

hello all i have a problem with my computer ita a pentium(r)4 cpu 3.00Ghz 3.00GHZ,960MB of RAM running windows XP home edition and it keeps reseting on me as if its over heating i think its called "the blue screen of death" i recently had some work done at home and opened up the computer to get the dust out of the fans so i took out both and cleaned them when i put it all back together it keeps reseting on me im lost any help will be most thankfull:cry egg

 

Open up again ( after powering off and earthing yourself) and check all power leads are seated correctly, and include power leads to hard Drives, and while you are there reseat your memory. if no improvement post back

 

i checked all leads their ok but i dont know what reseat means thankyou for your reply egg

 

re-seat means to ensure that they are properly inserted in their connectors by taking them out and re-inserting them, or at least pushing down on them to ensure they are in all the way. you should also check to ensure any expansion cards are correctly seated (inserted) and that the fans are actually working when you power up, especially the cpu fan.

 

thank you they are seated properly maybe its a heat problem how can i tell what temprature my CPU is running at?? egg

 

Just an afterthought but are the fans blowing in the proper direction. Front fans should flow inward, back and top fans outward, the CPU fan should blow down onto the heatsink.

 

the bios usually has a section that displays temperatures as well as fan speeds, consult your mb manual if you are not sure where it is there, or have a good hunt thru the bios setting screens.

software for windows that will display temps includes motherboard monitor, sisoft sandra and others, but you of course need to stay up long enough to run them. once you figure out how, you can use the software to monitor and alarm on high temps in future.

 

i think they are all bloing correctly is there any way i can define what teperature my CPU is at at the moment as i have just been reading about CPU paste ???

As kronckew says look in your manual to see where in the bios the temperature is showing. re-enlighten me .. the computer was running OK up to when you opened the case to clean the fans..?? did you take off the heatsink to clean, (thats the one that blows directly onto your Processor.) Look to see that the blade angle is facing toward the processor.
