Strange Issue

[winner4455]

I just build my new computer. It's have a strange issue, sometimes when I try to start it, it just shuts off and turns on 3 seconds later, shuts off etc. Sometimes though, it stays on. What could be my problem?

 

[hunter315]

please post your full system specs, it makes it easier to trouble shoot.

 

[winner4455]

Antec 1200
i7 920
HD Radeon 5770 x 2
Corsair TX850
Asus p6t deluxe
Corsair Dominator


Ps: Could this problem be the Power supply turning off to protect it self and restarts when the current drains?

^ It could even be an unstable BIOS configuraton...
Have you changed any settings in the BIOS ?
The 850TX has more than enough power for your setup...

As hunter requested please post your specs.

To take a pop shot at what you are saying without knowing anything else about your setup I would have to say its either an incompatible driver/hardware conflict or a wiring issue.

Unplug all of the extra hardware you don't need to boot the system and reboot, if it still persists then check your front panel wiring to make sure you got it right, use your motherboard manual diagram.

One last thing, are you using Vista? If so, you could be using an old disk that doesn't have the patch to correct the ram issue. If you try to set up your system using more than 2 gigs of ram it wont operate correctly. You could try to use 1 or 2 gigs and see if that helps.

As I said, I'm swatting at air without knowing more about your setup configuration but its likely to be one of those suggestions...

 

[englandr753]

Lol, I guess I took too long responding.

What operating system? Also, are you trying to overclock? If so go back to stock settings until you are stable...

 

[winner4455]

I haven't even got to POST yet... I believe it is a wiring issue. I'm gonna make sure everything is insulated, and post back tomorrow night. Thanks!

Go through this checkList then -

Does it ever stay on for long? I had a similar issue once, turned out I didn't have the cpu cooler fully snapped down. Seriously I hate those cpu socket snaps, just give me some bolts with springs.

Reset your CMOS to defaults before trying to power up a new build.

 

[winner4455]

Will do, I was reading an article at ASUS technical support and it said to do the same thing. Will try when I come back home.

Also, my socket is fully snapped down as well as my cooler.

 

[englandr753]

It sometimes pays to reseat your cpu. I'm a pretty experienced builder and this still happened to me. I can't explain what it was but nonetheless it worked out in my favor I had two similar systems to swap hardware:

If resetting the BIOS and nothing else mentioned works you need to reseat the cpu and the heatsink anyway just to make sure.

 

[winner4455]

Eh I'll try once again if nothing prevails (reseat the cpu).

 

[winner4455]

Reset your CMOS to defaults before trying to power up a new build.

Did not work

 

[englandr753]

Another thing, did you look up your cpu support list for that motherboard and make sure the current BIOS supports your cpu? It could take a BIOS update to make your board compatible with your cpu...

 

[technuttso]

There are 2 versions of i7 920 CPU.

Rev C0 that works with BIOS 0402

Rev D0 that works with BIOS 1303

Check your BIOS version and your CPU version.

 

[winner4455]

Okay

I have d0 I believe as it says SLBEJ on the box.

 

[winner4455]

How do I find my Bios version without a post?

 

[technuttso]

U have BIOS info write on motherboard PCB along with the name or even the box pack of the motherboard.
On the PCB ASUS write something like this: ASUS P6T DELUXE rev. 0xxx or 1xxx (no mater) \or bios xxxx.
The "rev.(bios) xxxx" is your bios version.

 

[winner4455]

Opss, I have V2, forgot. It's mobo rev 1.02g

 

[winner4455]

How would I flash the bios without a boot?

 

[technuttso]

If u don't have a friend with a C0 i7 920 CPU u may find a computer shop that will do this for a small pay (i think). In my home town these service cost in about10 to 20 Euro at maximum.Find one near your home, off course. Pay attention on the choices u make at your next computer build. Good luck and enjoy your rig.

 

[winner4455]

Great. Is there any other way?

 

[technuttso]

Return the CPU (refund) and get instead a C0 version. May be 920 or 940 i7.

 

[winner4455]

Considering the $42 restocking fee and shipping fees, it would be cheaper to find someone or a computer store that can flash it I guess. I could also use the extra OC abilities of D0.
