Just built my PC, not working

[fastiwrin]

Hello,

I just put together my PC (a lot has changed since my last one 6 years ago!) The fans power up, the CDROM drive blinks, but I get no output on the monitor, not sure what is going on. Does anybody have any suggestions?

Thanks

Welcome to PCMech.

First, we need some specs on everything you used.

Second, double check all of your connections and make sure the board has power anywhere it needs it.

Third, try our out of the case troubleshooter: http://forum.pcmech.com/showthread.php?t=132409

OK, here goes. For power to the board, I have the 24 and the 4 pin connectors hooked up. No beep signals by the way, the only stuff that happens is fans go on, cd rom spins, makes weird spinning sound like it's trying to read the xp disc, and then occasionally the fans stop and it seems like it is resetting or something.

Board: Gigagbye P35C-DS3R
Chip: Intel Core 2 Duo E6750, LGA 775 2.66 GhHz, 4MB L2 Cache 1333 MHz FSB
Mem: 4 1 Gig Sticks DDR2 Corsair TWIN2X2048-6400
HD: WD SATA 250 GIG
Video Card: EVGA e-GeForce 8500GT
Case: Antec Sonata III 500
Power Supply: 500 Watt EarthWattsPSU compatible with ATX 12V version 2.2 spec.

I would try it out of the case like the link Alaron posted says. Also, try with just one stick of memory.

One other note, just looked inside the PC as I turned it on, the heatsink fan spins for 2 seconds, then stops. Then spins again, then stops. Seems to be in sync with the first noise the cdrom makes.

Does this sound like a bad power supply?

Could be I had a Antec go bad once and did the same exact think yours is doing.. To rule it out you need another one.. Also this being a intel build, make sure the heatsink is installed properly. Many newbies have had issues like this and the problem being the heaksink not installed properly..

Hello, posting on behalf of fastwrin who is having log in problems, any help would be much appreciated since he is right in the middle of building this PC. thx!



"tried out of the case testing, still same problem. Is this most likely a motherboard, power supply, chipset or other issue? How can heatsink be on wrong? Double checked and processor is in right with a layer of heatsink grease and heat sink is locked in"

[Alaron]

The Antec Earthwatts power supplies are good quality, but anything is possible.

If the system still won't work after you try the out of the case procedure, you need to substitute parts.

Try with one stick of RAM at a time, you could have a dead stick.

Then try another power supply.

ON behalf of Fastwrin:



Each single DIMM works on its own, but not collectively. Any advice?


Thanks for the responses by that way, much appreciated.

Try setting the RAM speed to DDR2-667 if you can (with one stick...then save settings, shut down, and put the rest in). Sometimes chipsets can't handle 4 sticks at full speeds...

[skids929]

Oh behalf of Fastwrin:

Is it normal for the PC to operate when I switch the order of the RAM sticks? Basically I switched them up in a different order and they work now. Just want to make sure I don't have a bad stick and should return it.

thx

Test the RAM with Memtest86+.

[skids929]

Mahalo Cricket...I will try that out.

If it doesn't pass memtest at the rated speed, then try lowering like was already suggested to 667.
