Ok, so I have had a bit of a renewed desire to overclock my setup (at the bottom) since I have a GTX 470 on the way. Got 2GHz FSB/3.5GHz CPU/DDR2-1000 stable which was really awesome. I wanted to see if I might be able to squeeze out another 100MHz. Well, The computer failed to boot and did the normal starting to boot, turning off, rebooting that it usually does if you push and overclock too far. Except this time the computer never came back.

I hooked up a speaker to the motherboard to see if there were any error codes being thrown and nothing. I noticed that all of the fans connected to the motherboard seemed to be getting power in lumps (the LEDs are flickering a bit) with no difference being made if they are connected to the motherboard or to the power supply.

Now I did disconnect the PCIE power connectors from my 800GX to see if I could get the computer to throw a code and it did, so the motherboard seems to be at least partially working. I also removed the CMOS battery for both a short and long (1.5hr) time and it didn't change anything.

Is the problem with my power supply? Did I accidentally kill my motherboard? When I removed my video card to get to the battery did I somehow accidentally break something?

I don't really have any other power supplies I could use to test. I have one in my HTPC that has the connectors I need but not the amount of power I need (would it be fine as long as I didn't actually try doing anything?). I am just looking for more options to narrow down my issue.

Hardware is as follows:
Gigabyte GA-965P-DS3 v3.3
Intel Core 2 Duo E6550
2x G.Skill 2gb DDR2-1066
eVGA 8800GTX
OCZ GameXStream 700w

I would try testing with your other PSU. If you take the 8800GTX out, you should at least get the "no VGA" beep code.

I do get an error tone if I disconnect the additional PCIE power connectors from the video card.

I will see about swapping in the PSU from my HTPC. It's only a 400W PSU so if it is a PSU issue hopefully that will be enough to at least let it boot so that I can confirm the issue.

Confirmed power supply issue. I swapped in my HTPC power supply and I got the desktop to boot. I was kinda leaning towards this because of the light flickering I was seeing.

(Just to double confirm I reconnected the old power supply and still nothing)

Sounds like you may have just tried to draw too much power from the old PSU and killed it. Not surprising considering that it is an OCZ.

That is sad that a 700 watt power supply from a company that is supposed to be reputable can't handle an overclocked system with one video card. I hate that happened to you. Now I am glad I didn't buy one when everyone thought they were "the" power supply to get.

Yeah, I am a little peeved about it all. Needless to say I went a little more upscale in my replacement with a SeaSonic X-750 since I would rather not have to worry about a power supply breaking.

The last little kick while I am down is that the warranty just ran out this last spring, so now I can even get a repaired one to keep around for "just in case" reasons.
