I've just got new parts for a computer I was building and I put it all together but when I push the power button it turns on for about 3 seconds then shuts off. But then 2 seconds after it tuens back on. It keeps repeating like. What can I do to fix it?
Specs:
-CPU: intel i5 3550 3.3ghz
-MB: asus p8h67
-RAM: 2x4gb corsair vengeance blue
-PSU: spire 550w
-graohics card: nvidia geforce 9600gt
-HDD: WD 500gb
-CPU fan: arcic freezer 11 lp
-case: thermaltake armor a60

Thanks.

try this troubleshooting guide http://forums.techguy.org/hardware/5...em-builds.html

I did what the guide said but it didn't tell me how to fix it.

Did you try the out of case build? Not an Intel builder myself, but are you certain you have the HSF properly locked down?

I've tried the out-of-case build but still no dice.

If you have done the 'out of case build' with minimal components then you possibly have a fault PSU, CPU or motherboard.

First thing to check, do you have the correct BIOS flashed on the board for that CPU? Looking at the Asus website CPU support list here, there are different BIOS versions need dependant on the installed CPU, if you do not have the right version (or later) installed then you can have problems.

Looking at the components you have listed I would start with the power supply, I don't recognise the make and assume it was a relatively low cost unit. Cheap units are not a good idea, the PSU is somewhere you really shouldn't be cutting costs as every component in the system relies on that one part!

Is the RAM on the motherboard manufacturers Memory Support List (MSL)? If not, there is a small chance there is a compatibility issue between the RAM and board, although this would be fairly low on list of possibilities.

You must not have followed the guide. Did you miss the part where you swap parts with known good units ie pw supply, mb, cpu, ram???

How do I find out which BIOS version I have?

Also, Its says it's compatible with the Corsair Vengeance 1333GHz but not the 1600GHz. Does 277GHz really make much of a difference?

From your first post, I would suspect either you do not have the hsf installed correctly OR you have a problem with using a low end pw supply. Spire is not a recommended brand.

[crjdriver]

The bios version needed is 3506 and most likely your board did not ship with that new of a bios. Asus support can tell you what bios version your board shipped with if you call and provide the ser# from the mb box.

[crjdriver]

You have a LOT of problems here; most likely unsupported cpu/bios, low quality pw supply, ram not on the qvl list.....

The very first thing you do when attempting a build is check part support before you purchase.

The ASUS site says that board supports 32nm cpu's. The 3550 is 22nm. I didn't see anything about a bios update for it to support ivy bridge.

The OP's CPU is on the CPU Support list for that board linked below, as long as it has BIOS version 3604 dated 24th May 2012.

You like to think Asus know what CPU's their boards support

[Sixer]

So how do I fix whatever is wrong with it? Or should I just give it to a computer tech to fix it?

[black-wolf]

You're going to need another 1155 CPU to install temporarily to flash the bios. If you don't have that you need to check with a shop and see if they can do it for you.
