New motherboard powers but no boot or beeps

Hi,

I'm trying to upgrade my old system to a pentium4 pc but I'm having problems. First I bought the following equipment:

Iwill P4GB Workstation motherboard
Pentium 4 2.4Ghz 533mhz FSB processor (socket 478)
2 sticks of Kingston KVR266X64C25/128 DDR RAM (128MB 266mhz DDR2100) and another 256MB stick of the same type but a different make.

I put the whole lot together (and according to any website/manual i looked at they're all compatible) with my XFX GeForce fx 5200 AGP graphics card. Great I thought, this should work no problem. Of course it didn't. The power came on but there was no display on the screen and no beeps at all, just the processor fan spinning and a blank screen. So I bought a new cpu, a 2Ghz 400mhz FSB pentium4 this time. I replaced the other cpu and pressed the power button. The machine comes to life for a fraction of a second and then switches off after the cpu fan twitches. Hmm, I thought. Ok, so I bought a new PSU, maybe 300W isnt enough for p4 i thought. 500W ought to do it right? No difference. Ok so i bought a new mb, a MSI 648Max, again compatible with all my hardware. Same results with the 300W PSU but now with the 500W PSU, the 2Ghz cpu doesn't cause the whole thing to shut down, it just does the same as the 2.4 (no beeps, no screen). I've tried everything with both mbs and both cpus. I've tried with only one stick of ram, i've tried out of the case (incase of shorts), I've not had anything connected except cpu, memory and graphics card. I know the graphics card works and both mbs were new so i don't think they're broken. memory was also brand new.

Does anyone have any original suggestions? I've tried every combination that i have and have also tried resetting the CMOS and the battery. Also worth a note, my case doesn't have an internal speaker so i may not be able to hear any beeps. Diagnostic LEDs on a D-Bracket of my 2nd mb indicate only "operating system booting". Obviously however this is not the case as I get nothing on the screen and my graphics card is securely in place. Please help, this is really annoying and expensive! thnx

i Have the Same problem as you do , motherboard has power , fan spins , no boot no beeps , and sometimes fan has a little spin and stops in a second ... i tried everything , changed memory , GFX cards , PSU's .. nothing helped , always same output.

any help would be great ...

Some mbs will not let you mix the memory. It may be the same type DDR2 and the same Mhz 266 but if its not by the same maker as the other one it won't start. Also if the board has 4 memory slots they sometimes have to be in order. You may see like A1 B1 A2 B2 under the memory slots. if you have 2 sticks of memory than you would want them in slots A1 and A2 if you have 3 sticks then you would want them in A1 A2 and B1. Also if you built the system yourself make sure that the stand offs under the board are in the right place. One may be in the middle of the board when it should be under a hole. And I never knew they had boards that supported DDR2 and a socket 478 board but I guess they hide some. lol

Don't mix memory, either in speed, size, and especially brands in the same PC, your asking for trouble.

Use the biggest single stick, but before inserting it, clean the memory socket with some small piece of folded wet & dry, then blow out the crap, (a GOOD soft paint brush works well) then using the same wet and dry (1000 grit minimum) clean the memory contacts "carefully" sometimes a dry joint will happen with age.

Try again.

For the love of all that is holy, no.

Do not use wet/dry on anything inside that computer case. If, on the off-chance, there are any corrosion or tarnish related issues, the most abrasive thing that should be used is a Ruby Red eraser... it is abrasive enough to remove tarnish while minimizing the amount of good metal lost. One would want to be sure to remove all byproducts, of course.

Since these are new components, it is highly doubtful this is the problem.

Try running the board with the two matched memory sticks in the appropriate dual channel slots.

You won't get beeps if the speaker isn't hooked up.

You likely won't get a signal out of your AGP card if the MoBo has integrated video-- plug the monitor into the onboard video output, boot up and adjust the BIOS settings to go to the AGP slot. Once all your BIOS settings are fixed and saved, turn the machine off and switch the video cable to the card.

OMG... do not listen to this drivel... no sandpaper.... never...

And since you have a DDR capable MB, don't waste your bandwidth by getting the biggest single stick!

I have the same problem. I am trying to put together a PC to replace an old one and as soon as I plug the power cord to the back of my PSU, everything turned on: Fan working, including the Processors fan. I tried it, without any memory stick, I reinstall the processor to make sure it was done correctly. But when I powered it back again, the same issue. It powers on its own. I know its not PSU because I bought a new one. The only other possibility that I could think of is bad motherboard or bad processor (P4). The only thing though, all of this parts are all brand new and straight from NewEgg.


Any ideas gentlemen!?!

Call Newegg and find out how to get a return material authorisation... I'd do both CPU and motherboard just to be safe. SOmetimes you just get bad parts.
