Actually i bought this Pc One and a Half Year ago and i put Intel Celeron 1.1GHz Cpu in it, while in a situation a pin of

that cpu got broken about 6 months ago..then i bought the present Intel Cele 1GHz CPU.. initially ... well not initially but

through out the past 6 months.. now what the heck is its problem i am not sure..
help guyz before i got any serious problem..

......do you have an option for "Set-up bios default"? Maybe there is a setting wrong somewhere. Does your cpu fan really go 7600rpms .........

i had did it already.. thats not doing any thing for me (setup defaults)..

7600rpms

Click to expand...

noway.. thats just for reference.. only..

......the reason I ask is do you have your cpu HSF hooked into the mobo? If not, some machines you need to disable fan monitoring to get it to boot right.....

CPU Fan Speed: 7670RPM <-- wow! what fan u using?

cpu hsf hooked right into the mobo.....

u mean p4 stock hsf? i thought its around 2300 rpm? urs is 7000++

......have you tried flashing the bios? sometimes the bios get corrupted and a flash or a simple clear CMOS will resolve things. Did you change or add anything to the system before this started happening. Sorry, running out of ideas .......

ciku,
He said thats not the real rpm ..........
