Hey there [H]ard Community! I have been a forgoer of this forum for a while. I like looking at the galleries and such, that kind of follower. I recently bought components to a new rig. They are as follows:
Q6600
4g kingston hyperX RAM
XFX 8800GTS 640mb
Seagate 320gb hdd
dvd/cd blah
Intel D975XBX2 Mobo
Cooler Master 830 Stacker
and Thermaltake toughpower 850watt

Now here is where it gets squirrelly. So I assemble my Pc, thinking I have everything connected right. I go to start it up. Turns on and then off in less than half a second, like a power surge. I checked connections and tried again. Same. I started taking components off, video card, ram, cd and finally hdd. Once the hdd was removed it started up. I grabbed an old hdd and slapped that bad boy in there, started reassembling, testing it every time I put in a new piece of hardware. Then I get to the Video card. Does the same thing. I get severely frustrated and go to sleep. The next day(today) I take it to my friends computer repair shop. They conclude the PSU is faulty. I say ok thanks. I burn to best buy and pick up an Antec truepower trio 650 watts. I get home and slap that in, same problem with a twist. NOW it will stay on with the new hdd in, but not the video card. I read a little more and I soon find out I did not plug in the 4 pin power connector to the left of the CPU. I plug that in, and still, I press the power button, it turns on then immediately turns off. I have the pci e cable attached to the video card, everything is plugged in correctly. I am stumped. Again, the problem is with all of the components in place, I press the power button, the machine turns on then immediately turns off like a power surge or a short. HALP!

thank you
 
Yes, no go, when i press the power button theres power for a millisecond and then it turns off.
 
Sounds like a short. Is this inside the case? If so, take it out and set the mobo on top of its box, and plug in only the essentials for POST: cpu/hsf/mobo/single stick of ram/vidcard/psu/kb/monitor

You could also test the PSU by jump starting it, and making sure it turns on and stays on.
 
The only time I've seen that problem of the fans just twitching when you try to boot up is from a bad PSU.

Do a minimum spec build with the mobo resting on its box.
Just have MoBo, CPU & HSF, PSU, Vid card & 1 stick of memory. KB, mouse and loadspeaker help.
Does it boot or do the fans still twich ?
Remove the vid card and see if it starts.
If it does, do you get the bios beeps for a bad vid card.
Now try without the memory in.
Does it start and do you get the bios beeps for bad memory ?

If the fans only spin up with the vid card out either its a bad vid card/slot or the psu cannot supply the power needed to boot up with the vid card in.
Do you have a less powerful/ different vid card you can swop in ?

Luck ......... :D
 
That is the conclusion I have come to, either the video card is bad or all three pci-e slots are bad. Will a bad video card short out the entire pc like that?
 
Don't think a video card could kill a system unless it was too much for the power supply and it died. And a power supply can kill an entire system.

If you have a spare PCI-E video card, try using that. If your PC boots, then your video card is the problem. If it doesn't then the mobo is the problem.

Did you do what Tigerbiten and enginurd suggested? Reassemble the PC out of the case with the mobo resting on the mobo box?
 
hey there,
make sure u havnt screwed down you motherboard to tight, mobo screws should be fastened not completly hammered down to the casing..and make sure no other random metal pieces, such as the back bolts/wires are not touching the mobo, only put in the back bolts that u need, ie so they all match the holes..
 
I'm having the same issue with my new rig, and I've tried every trick mentioned here before, but thing is that with no vid card and no memory I don't get any beeps.
Fans spins and PSU stays on. I did assemble the PC in 2 different cases as well over the cardboard box.

I never pay to somebody to fix me a computer, sounds funny but I used to be paid to fix them ( long time ago) but this is getting on my nerves and I don't want to spend any more money/time dealing with this **it, leave alone the frustration

thanks for any advice .... in advance
 
Please make a new thread. In the new thread, please post the specs of the PC, what troubleshooting items you've done and an exact description of the problem.
