Help me! please...

more specs of your system would deffenetily help. Motherboard model, cpu psu brand

Man... that is so weird. I've seen so many post on this.

In general basic observations, it should stay on and constantly beep, indicating no ram is present.

Sooooooo... I think you better take that the HSF, and CPU out/off. Inspect the 775 socket for bent pins on the MB socket. I kinda bet you have bent pins sorry to say.

I've seen so many people experience this type of problem in the home built section, and advise so many different things to help solve it, that nothing worked for them.

Until recently in this section, a guy posted basically the same problem. Turns out he did have 2 bent pins on the socket.

I do agree its best to put a system together will all parts when you get them, then power up a system without all the parts.

The thing is, I've seen this type of problem on the forumz with system with all parts installed (total system built, nothing missing).

But like I mentioned on my first reply, it should stay on and constantly beep.

To the OP, if this is your first time installing an intel 775 socket mb setup, plz watch this video:

Intel 775 socket install

It does have some good points to follow/consider. Although, I don't agree wearing gloves, cause for some reason, I think I'd have butter fingers in trying to hold stuff.

:?

Try running the MB out of the PC case with none of the PC case wires hooked up.

Always of a chance of faulty buttons, or wires hooked up incorrectly, or some kind of unseen short from the bottom of the MB to the PC case plate.

Edit:

OR.. maybe that is how it suppose to act without ram.

A) What?
B) The RAM is is still at the post office
C) Yes
D) There is no 6-pin
E) I think so, I didn't change it.
F) It is plugged in right

I am using a XFX nVidia 7600GT. and I was told the FSP 450watt could handle thsi rig by far by many people.

A. What?

. o O ( I was thinking of that insurance commercial when the cave man was responding to that lady)

He's talking about the CPU power, which is 4 pin square (not rectangle) with yellow and black wires. Some MB use 8, but 4 still can be used.

Edit:

That can cause a system to power off, then back on repeating. (if its not hooked up)

I have a DS3, which is virtually the same as the S3. I believe what you are describing is normal for this board.

When I first hit the power button, my machine comes on for a second and then goes back off, and then comes back on and boots. According to Gigabyte, this is normal, and I have never had any problems with it.

The CPU fan probably isn't spinning because without the RAM to boot the machine, the CPU has nothing to do, and therefore generates too little heat to trigger the fan. My CPU fan barely spins for awhile after bootup, until the CPU starts to build up some heat.

So you're probably OK, but let us know how it goes tomorrow.

DO NOT WORRY


i had a gygabite 965p ds3 which is the same thing as yours (wella lmost), when my ram was NOT compatible, it did the exact same thing, once i changed the ram , no more problem .

i would bet it does the same thing when you don't put any ram, probably a typical behaviour of these motherboards. so don't worry man and wait for your ram, and DO NOT FORGET that even if you plug in your ram , you might experience the same thing , it does not mean something is wrong with your components, but rather an incompatibility between your mobo and ram.

i hope you chose your ram carefuly, the 965p is a little bit picky specially for the 800mhz rams.

Thunderfox i had for awhile your "problem" when i tried to overclock my cpu d 805, i put a memory ratio of 3.3 , this caused the problem you described (the machine starts and shut off , then starts again after few seconds)

when i changed the memory ratio, the problem was gone... well that is just an information that you might find interesting.

Ok, THANK YOU EVERYBODY! I am very happy we figured out what is wrong, and I am not going to touch it until the RAM is in again. You guys are great, I really appreciate everything you guys did. Thank you again!

Ooo, I did not do that. But I didn't run the CPU for more than 10 seconds at a time, but I should get new paste before running it extensive lengths now. I don't have any though... But then again I DO work at a computer store... lol

Actually, you need to get new paste before running it AT ALL.

Why? At my work when we take off the cooler for a little we don't replace the paste, and we have never had a problem.

You work with computers for a living? 8O
Why would you take a heatsink off for a "little"? :?

And yes, you need to clean off the old paste with 90% Isopropyl alcohol and apply new paste every time you remove the heatsink.

Everything turned out fine. Thank you everyone!
