| fried processor?
My processor overheated to 90 degrees Celsius. i waited a while and turned it on again when it overheated almost instantly. It was overheating because the cpu heatsink retention divide had broken and become dislodged from the motherboard. I replaced it after about three days. Now when i turn it on it gets stuck on the P4 logo screen and does nothing. I talked to the company and they say it is not reading my keyboard but i do not think that is the problem. i think the processor may be fried but wanted a second opinion before i dish out 200 dolars. I would appretiate any insight you could provide. |

i cannot enter the bios it freezes at that screen and it will only respond to the off switch. I cannot try it on another computer. i opened it up and took out the processor to look to see if i could see any physical damage and the heat spreader fell off. |

| probably a 478.
id say its overheating and clocking the speed really low to protect itself from damage, so low infect that it malfunctions.

is there any way i can force it to run at a higher speed because i have fixed the heatsink so it should not overheat. |

| well first, are you able to move the heatsink easily or does it seem firmly placed.
is it clean ?
does the fan operate well ?
if the heatsink was seperated from the chip, you may need to clean the contacts of the heatsink and chip and regrease them with fresh thermal grease, there may as well be air pockets and dust contamination between the heatsink and processor if it seperated, especially if its never been seperated for a few years, the grease may have solidified thus not providing proper heat transfer.

if s cpu is dead but still in the stocket the only way to know if it works is it should still make heat right? |

| well one way i used to discover if the cpu was shorted, i would keep the heatsink off and place my fingers on the chip, turn the pc on and with my other hand ready to pull the power plug quickly, if the chip would get red hot burning enough to burn your fingers in less than a second, it is no good, if it got moderately hot in a few seconds, like 2-3 seconds, it was okay.
a shorted chip will draw massive amounts of current heating it up very hot quickly while a normal one wont heat up so quick.
the problem is some power supplies dont have a well built type of short protection built in it allowing more than necessary current to flow to the cpu if the cpu is shorted, there is a regulator on the mobo that will be the first to open up from not being able to handle the current draw, rendering the mobo useless.
this is why testing a suspected bad cpu on another mobo will sometimes damage that mobo.
this is especially true with older AMD cpu's

I would appretiate any insight you could provide. First, if a PC gets 'Stuck' @ all -@ a logo screen, it's definitely not the CPU...Sorry, just got back from vacation  It really sounds like a short [Was the Rig grounded] Did you try another keyboard, if you have and it won't 'see' the keyboard (Does the keyboard light up when you turn the system on; if it does -Then it's not the keyboard) then it sounds like A/A ~shorted & the mobo.
Just in case do you have more than one memory chip in the system, if so what happens when you take one out?
Some system specs might help?
Cheers

I have tried multiple keyboards that is what the mobo company said to do then they ran out of ideas. I have a abit ic7 max3 mobo a pentium 4 3ghz processor 1 gb dual channel ddr 3200. x connect 400 watt power supply, a geforce fx 5900 256 mb memory, a sound blaster audigy sound card, a maxtor 80 gb eide hard drive and 2 cd rom drives. It has one short beep when it boots up as it should the it hangs. I kind of think it is the motherboard now because a properly working motherboard displays the problem usually if it can display anything such as memory error or keyboard error or something like that. thank you for any help you can give me |

Have you tried clearing the CMOS (resetting bios to defaults)? |
