OK,

I just got done assembling my new PC and when I go to start it nothing happens.

The reset button seems to solicit a response, the lights start and stop right away.

Could anyone having any knowledge about this situation please help me out. Than you.

John :thumbsup:

Did you use thermal compound between the CPU and the heat sink?

Is the fan on the CPU heat sink spinning when you start up?

Is you RAM properly seated?

Did you check all of you connection?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Did you put the copper standoffs between the case and the motherboard? I didn't my first time building my computer and it kept doing the same thing, in which it would start up for like half a second and then just turn off.

OK,

1. Did you use thermal compound between the CPU and the heat sink?

Yes I did, I put to much on the first time so I completely cleaned it off, reset the chip, made sure no grease got where it shouldn't be then I put a rice size bead of grease on the CPU, used my finger to spread it evenly all around on it.

Then I snuggly secured the heat sink to the CPU, I hope not to snug, I did get the impression that it should be fairly secure so that the heat is carried away from the CPU.

2. Is the fan on the CPU heat sink spinning when you start up?

Nothing happens when I press the start button. Nothing what so ever. There is a led light lite by the connectors that connect the front on/off buttons to the MoBo?

However, when I hit the reset button in the front all the fans and lights turn on for a second including the CPU fan.

3. Is you RAM properly seated?

I did check that again and it seems to be properly seated. I'll check it one more time.

4. Did you check all of you connection?

That I know of, yes I went over all the connection to make sure that they are connected correctly.

5. Did you put the copper stand offs between the case and the MOBo?

Yes I did. I heeded your first warning and made sure that I found the spacers and put them on correctly.


So, all the basics checked and still no start. I'll check them again cause what else can I do.

Can you put the heat sink on to tight? I did make sure that it is secure.

Power supply seems to work sense the lights and fans go on when I hit the reset button.

Can't think of anything else.

But I really would like to get the new PC up and running. I'd love to see how much better it performs than my old clunker.

John :thumbsup:

There's a possibility it could be grounding out on the case. The best troubleshooting method is to remove everything from the case and try it on the table, on top of a piece of cardboard
You have both connectors hooked up to the motherboard, correct?

Mark had the same thought that I had, is the PSU connector for the CPU plugged in on the motherboard?

OK,

've taken the MoBo out of the case and put it on some cardboard. Still the same result, nothing with the start button and a second on the reset.

What is the PSU, Power Switch Utility?

Unplug the front panel wires from the motherboard and on the 2 pins that are for the power switch, touch the 2 together with a screwdriver blade. If that doesn't turn it on, remove the power supply altogether. With the PS plugged in, Take a small gauge wire with both ends stripped, or even bend a paper clip and short out a black wire and the green wire on the 20 or 24 pin plug. If that doesn't turn on the power supply, it's bad

OK,

I "Unplugged the front panel wires from the motherboard and on the 2 pins that are for the power switch, touched the 2 together with a screwdriver blade" and the same result:

It's starts for a second and then shuts off.

"If that doesn't turn it on, remove the power supply altogether. With the PS plugged in, Take a small gauge wire with both ends stripped, or even bend a paper clip and short out a black wire and the green wire on the 20 or 24 pin plug"

I did this also and he power supply does start and stays on.

I touched a black wire to the "dark" green wire to get this result. Touching to either of the "light"green wires had no result.

I take it that this means my power supply is good.

If that is the case, now what?

Oh, by the way thanks for helping me here, I appreciate it a lot. This is my first time doing this and I'd have no idea what to do. So, thanks.

Could it be the heat sink?

It has that "H" bar-band that touches the back of the mother board. I do have the "Insulator" and the "Cushion" on the "H" bar-band touching the MoBo so it should be protected, but maybe?

Also, one strange thing happened on the way to using the paper clip to turn on the power supply, the front panel light up? Why would the front panel light up if nothing is connected to it?

Oh, also just noticed that the DDR3 slots have nothing in them, do they need something in them even if not being used? On my old PC when two DDR slots were not being used there was two blank 'DDR's in them.

Just a few thoughts.

Oh my %&^,

Why didn't someone tell me that these new PCs have """TWO""" power hookups and not just one.

Jeese, the second 4 prong power supply goes to just the left of the heat sink.

So it's Bingo for me.

I have POWER!!!!

WOW,

I'll get back to you when I get it back together and look it over.

According to the manual it only says you have to use one or the other DDR2 or DDR3 not both together.

We both did, you were just too frustrated to see it :thumbsup:
The only setups that have to have all the memory slots populated was the old Dell Rambus systems
Glad you got it figured out
