Hey everybody.

So I ordered all new parts for a brand new PC recently.

Intel Core 2 Duo E6750
Gigabyte GA-EP35-DS3P
2GB DDR2 RAM
Seagate 500GB HDD
Atrix Gaming Case
GeForce 8800 GT Sonic 512mb GFX card

Here is my problem... I hooked up my mobo, PSU, CPU, heatsink and GFX card first.

The computer would turn on, but not POST or display anything from the graphics card. All the fans were going, and on the mobo itself the "CPU load" LEDs were all coloured, so I assume that meant the CPU was at full load.

I couldn't figure out what was wrong, so I turned everything off, took out the mobo and did a test outside of the case. Same thing.

Put the stuff back in, all in the same place and order, and now when I push the power button all I get is the fans going around 2-3 times and then a shutdown. I don't even think the computer itself turns on, there is literally about a second's worth of power in the PC and then it's dead.

The PSU can't be fried because this happened once before and I fixed it, but I can't remember how and/or replicate the solution.

I've been trying to sort this out for 2 days now, and it's doing my head in. I've double checked the CPU, heatsink, grease etc.

dai

set it up out of the case on a piece of cardboard with
cpu
video
ram
speaker
and see if you get post
check you have the correct amount of standoffs no more no less
that they line up with the holes in the m/board
usually 9
when you disturb the heatsink you need to redo the paste
what power supply is in it
brand
wattage

I took it out, the same thing happens.

My PSU is 500w, made by Atrix.

I've been reading that the problem could be PSU related, but this is where I am not sure because I had this exact same thing happen as I mention, I just can't remember for the life of me how I fixed it.

dai

the psu is rubbish and underpowered for the system
you need to be up here

Yeah thanks I realised that earlier so I just so happened to order that exact same PSU :D

Would this be a fix to my problem, do you think?

dai

would expect it to when you are underpowered the problems can be multiple and diverse

Do you think the few times I tried to power on my PC could have damaged the motherboard at all due to the incorrect powering?

dai

not likely unless you heard a popping sound and smelt burning

Nope then I didn't.

Sorry, another noob question.... When I put my CPU in and close the lid, and then pull the lever down to close it, I can hear this kind of squashing noise each time.

Well not squashing, more like compacting. The first time I installed the CPU it didn't happen. The second time, it did. For the third time I removed it I checked all the pins and it seemed okay, so is this just the force of the bracket pushing the CPU in?

dai

that's not normal,are you renewing the paste when you re-set the h/sink on top

It doesn't happen when I apply the heatsink - it happens when I put the CPU into the socket and pull the brass lever down to keep the CPU in place.

dai

i understood that,i gathered you had been putting it in and taking it out a few times and wanted to draw your attention to renewing the paste

I doubt its your power supply, I am having the same problem as you with booting up and it shutting down right away. I have a great power supply (corsair 620W)

L.G.S

Sorry, yes I did renew it, and I didn't over do it, or under do it.

My new PSU came today - it powers on the PC.

But I still have the same problem or no posting, no beep codes and no visual output.

dai

if you remove the ram and power up do you receive the bios error beeps

No it doesn't.

this would point to the m/b being the problem
