PC Wont Turn On

[dfnkt]

EDIT: This issue has been fixed. The Antec NEOPower 480 is defunct (tee hee like my name). I have contacted Antec @ 1-800-22ANTEC and they will be replacing this with an Antec NeoHE 500. Thanks for the help


Ok guys, I am looking for a bit of input on my problem. I built this PC 2 years ago, AMD Athlon 64 3800+, 1GB Corsair XMS, DFI lanparty ultra-d mobo, antec neo power PSU. About a year ago I did some work to the inside of the case, routing some cables etc to improve airflow, after getting everything hooked back up, the front panel connector for power was a little bit strained (stretched). And about 6 months ago I started having issues where when I turn the computer off, it is very hard to get it to turn back on (with the power button on the front of the case). So yesterday I shut the computer down to clean up some cable clutter and now it refuses to turn back on (either with the power button, the power button thats built onto the mobo, or by shorting the jumpers used for power. I tested the PSU and the rails read good (12.2v & 5.05v) However with a PSU tester (not sure how accurate it is, its a POS from radio shack) my -5v lead is dead and the LED on the PSU tester says the PSU is overvolted.

Now my PC has been overclocked since I got it, I am going to reset the CMOS when I get home, I know there is a setting in the mobo that controls the juice that the motherboard is given to power up, I wonder if it is to low, I'm going to get them all reset.

So any other ideas? I checked the CMOS battery (it was good) and even replaced it. It just happened last night so I havnt had time to get it downstairs and put it on the bench to test the ram and the PSU competely.

Don't worry about the -5V since most modern PSUs don't even have a -5V line (it got voted off the island ). Are all four :camera: power fittings connected? #1 sometimes gets overlooked.

3 and 4 have been the only ones connected since I built the PC, #2 I had heard was for stability, and since I hadnt had a problem with reboots/shutdowns I opted to leave it unplugged. #1 is sort of hidden, ill give it a try, not sure what type of connector it is or if my power supply has the dongle for it (looks like a fan header)

I did get it to boot this morning for a second and then it gave a set of beeps (sounded like CMOS checksum beep) since i had the battery out, i hate having to be at work with a down PC >_<

#1 is like a floppy drive would take. You might need to dredge up the right cable for the NeoPower, but it ought to have come with one.

Big picture: the NeoPower didn't have exactly the best reputation in the world. If it were me, I'd consider running out and buying an Antec EarthWatts (built by Seasonic) or ordering up another good-quality PSU online, depending on how quickly you need to proceed. Good luck!

Well the entire reason for turning off the computer in the first place was to clean up cable clutter and hook up a PS2 keyboard so i could boot into safemode and try to re-install WoW (CD install giving me fits)

I will probably look into replacing it with a SeaSonic PSU as soon as possible, put one in a friends computer awhile back. Getting married the 15th of Sept, so money / time is really tight at the moment

Edit: wonder if my psu still has warranty? Ill have to grab my newegg order history and find out when I bought it.

Edit2: PSU purchased 7/5/2005 - Hope it's a 3 yr warranty :X

I'm wondering if the mobo could be getting grounded, any thoughts?
