CPU problem Replacing 2.53Celeron D with 2.8 P4 Please Help

[D.8080]

P4 2.8"C" , 800 mhz FSB. Socket 478. HT.


Unsupported by this board, so that is why I asked for specs.

I got it to boot. Then I turned it off to put the case back together. Now its back to doing the same thing...

[FDIV]

lets rule things out.
-It's not overheating, pentium 4's will slow down but continue to run when they get hot. An insufficient fan will make it slow not non-functional. Beyond that the fan is probably fine.
-Motherboard might not support the chip period. I tried to look the board up but ms-6577 is not a valid motherboad model. You must have the number wrong. I doubt this is the problem (no support) simply because your dealing with a fsb that is within what you know are the boards specs. I would find your actual board model number and do a little searching to be sure.
-Bios is old and needs to be flashed to accept this new chip: This is my bet. I had this happen myself with an older board and a newer pentium 4 chip. Exactly the same symptoms. Power bliped on a spit second and then off. I would find a bios update and flash it. (This is always a good idea when upgrading a chip.)
-Power supply is weak: don't discount this, pentium 4's do eat more current then celerons. That being said, the cpu will not be drawing that kind of current on post so I think your safe at least untill you start playing fear or far cry or something.

So, do some research on the web to find if you board supports the chip. Flash your bios and cross your fingers.

keep your stick on the ice.

The board number is correct. I have no idea why it isn't listed at msi. This board is out of a compaq presario sr1103wm. I got the computer to start 2 times in a row with the P4. Then I turned it off for less than 10 minutes and when I started it up again it cut right off. I have tried everything I know to do. This is most likely going to b a bad cpu. If anyone has any ideas they would be much appreciated.

Interesting. I did not know this was out of a proprietary machine. This changes much. Often proprietary machines such as Hp, Compaq, or Dell specificaly cripple the Bios to prevent overclocking and to limit the end users ability to upgrade cpu's. You may well be dealing with a board that will not support the cpu. That is now my bet.

[doug2060]

Could it possibly have something to do with the power switch? I know that sounds strange but I unplugged the switch from the board while clearing the cmos. When I plugged it back in and pressed the switch she fired right up? Even guesses are welcome if you have one...

Fdiv is probably right.. I had an IBM piece of SH*t that would not take a faster P4 and would not use any kind of DDR.

Anyway... guesses......

- test the new cpu again on another system to make sure it is working


Fact:
A few years ago I had a similar problem, cpu and mb worked fine ( taken from other systems ). When I assembled it into the case it wouldnt boot properly. It did a few times, then it stopped. So I fitted fibre washers ( any small M3 not metal! will do ) to the posts holding the motherboard fixing screws in the case. Problem solved.


other wild guesses.....
- check all the connectors, make sure each connector is in the crimp properly. It can be pulled out if not careful.
- take all the cards out, leave the video card in. Disconnect all HD and FDD and ROM drives.
- Try a new PSU
- check all the chips are socketd properly ( this really applies to older motherboards! )
- look at each pin of your new CPU. Is every pin there? Look in the socket - is there any debris in the socket?

....

good luck, it is very annoying when things dont work.

Ya... check to make sure you really have either this or this then...:

Intel® Pentium® 4 Processor 2.80 GHz BX80532PE2800D 533MHz 512K

Or

Intel® Pentium® 4 Processor 2.8C GHz BX80532PG2800D 800MHz 512K
Intel® Pentium® 4 processor 520 w/ HT 2.80 GHz BX80547PG2800E 800MHz 1Mb L2
Or
Intel® Pentium® D processor 820 2.80 GHz BX80551PG2800FN 800MHz 2x1Mb L2
Maybe you got a Pentium D and your board don't support it?

I would like to take this opportunity to thank everyone here for helping me with this issue. I tested the cpu in my neighbors system. It worked flawlessly. It has to be a mobo issue. I've tried everything. F it!

[doug2060]

OK, I have isolated the cause of this problem to the cpu startup temp. When I take off the heatsink and fan and hit the power button a few times which warms the cpu it starts up. I can immediately turn my pc off and it will start back with no problems when I hit the power button. If I wait a several seconds I may have to press the power button 3 to 5 times before it starts. When I put the heatsink and fan back on it can take many presses of the power switch for it to start. Its like trying to start an old lawn mower. Whenever I do get it started it works fine passing all benchmark tests and doesn't even overheat. As a matter of fact the P4 runs much cooler than the celeron D. Does anyone know why this is? Any adice or guesses would be much appreciated. Thank you...

Is it possible for the power supply to cause this? I installed Hmonitor which is a program that monitors your systems temps and voltage ight on your desktop. Everything was good but the power supply had one item that showed up in the red for possible low voltage.

[gshv]

Yes, it's possible. I had similar problem with one of my computers. The computer has Athlon XP, but it's not important. The computer would crash randomly immediately after booting to OS. After 5 - 10 minutes the system become stable and could work for hours with 100% load. One day the computer couldn't boot at all. My first reaction was to blame either the processor or the motherboard. It turned out the problem was a bad power supply... So, try to replace your power supply with some other power supply - it may fix the problem.

I have that computer that you got the board out of, the Compaq Presario SR1103WM. The reason why the CPU that you listed isn't working is because the board that came with the SR1103WM only supports FSBs of 400/533 MHz, and the processor you're trying to use has a FSB of 800 MHz. The board does support HyperThreading, and it does support Pentium 4 processors with a Socket 478.

If you want more information, you can go to Intel's Website:

(Oh, and by the way, the board is an Intel 845GV)

I hope that helps.
