EPOX MB not Working

post #1 of 19
Thread Starter 
Oh man. This is a long story but I really need help.

Okay, so my computer inexplicably died on me about 2-3 weeks ago now. I came home from work and it was toast. Power supply was totally dead, motherboard was totally dead. Hit the power switch and NOTHING. I RMAed them both and just yesterday I finally got the mobo back... I hooked up the mobo, RAM, CPU, Vid Card and 1 HD. It worked... things seemed to be running fine and back to normal. Only thing was, my vid card (6800ultra)is supposed to have at least a 450W PSU. I was running a 300W model because that's all I had but I figured it would be fine as long as I didn't do anything graphics intensive and kept only the necessary components hooked up. I left it on overnight with winamp playing music and SoundForge recording off my minidisc. Not super resource intensive or anything... then in the middle of the night I wake up and hear it shut itself off. I was like, shoot that sucks, whatever I'll deal with it in the morning.....

so today I turn it on and the CPU fan spins up, the vid card fan spins and the hard drive makes 1 sound and that's it. Nothing on the monitor. I'm like crap, this looks like a dead CPU. I switch the video card, nothing. Test them both in a seperate machine and they both work. Test the RAM in the other machine, it works as well. So I say okay, looks like I need to A.get a real PSU and B.replace the CPU. So I go out to Tiger Direct tonight and drop $350 on a 550W X-Connect and a 3700 Sandie (ooh baby!) I'm super stoked and I race home to set it all up.............. SAME THING. No video, no post, 1 noise out of the HD and that's it. WHAT THE HELL!!?!?!?!??!!!!! I'm soooooooo mad right now. I just want this damn thing to work. Seriously.

So I have a brand new motherboard as of yesterday a new PSU & CPU today.... could underpowering the system last night somehow have messed up this mobo? When I turn it on the CPU fan spins up, which is connected to the mobo... and the "80 port" LCD readout on the board comes on just like normal. The only thing I noticed abnormal with the mobo is that the case power light isn't coming on when I turn the machine on like it should. Tomorrow I am seriously thinking about going out and buying a new mobo. This is outrageous. I'm about ready to kill something. WHAT IS HAPPENING? ANYONE? PLEASE HELP.

Make sure you push everything in tightly. Make sure the RAM is all the way pushed in, check for missing connections somewhere on the board, and try restarting the build from the beginning. Maybe you screwed something up along the way and restarting will allow you to see what you did wrong. I had this problem a few weeks ago and it turned out I didn't push my RAM in quite far enough. Heh. Took me a few hours to figure it out.

Did you reset CMOS (either by jumper or by removing battery and power chord?)

Well, scenario A is you boot it with no molex connector in your video card. You'll hear a loud BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE EEEEEEEEP and that means no power to the video card, and also that your mobo is not fried. Could try that, what Kind of beeps are you getting, if any?

A cmos reset always helps!

Try checking for shorts aswell.

Have you even considered checking to see if your hard drive may be the issue. Go to your manufactors site and download the latest utility which should be able to do a long test to make sure the is nothing wrong with the sectors. If it reads out to 0 or 0 errors it's pretty obvious theres nothing wrong..

BTW, Do you get any beeps when you recieve a post error? If so which BIOS/ version are you running. It's important to know your bios beeps, because theres so much versions that it usually is differen't from other identical ones within mobos.

I get no beeps when I startup. Like I said though, the mobo lights come on and the fans spin, for whatever that's worth. I took the mobo out of the case and I have it sitting on my desk right now. I hooked up only the vid card, CPU and fan, and 1 stick of ram in slot #1. I made sure to press it in extra tight. Still no video. My vid card takes 2 molex connectors, which are securely plugged in. I have the mobo power cable in snug and the 4-pin 12v cable as well. I don't know ho much more I can simplify it or what I can change/do.... I'm going to try removing the battery for a while and see if that does anything

No seriously have you tested the hard drive... It sounds more like a hard drive issue than anything else. If your hard drive only spins once, it most likely may be your hard drive. Take my advice, find out your hard drives model number, go to your manufactors site, then download it's utility. Copy it onto a floppy or cd, then set either your floopy or cd-rom as first boot priority in your bios, then save changes. Then let the program check the hard drive. If it comes up with 0 errors and still confuses to post with your system, completely wipe the hard drives data to 0 binary.

I had this issue less than 2 weeks ago, where some files happened to get corrupt somehow. So i did a test, and it passed with 0 errors. Although it still wouldn't boot, so I tried a secondary hd laying around and it worked. So i wiped the hard drive to binary 0 and everything was fixed.


Also be sure to check your hard drives jumpers you may have it set on the wrong jumper. If you are only using one hard drive you shouldn't have to place in a jumper. If you are running two you should set them in the priority of master/slave. The diagram is usually described on most newer hard drives, if not jsut ask me i'll tell you the jumper settings.

Well right now I don't even have the hard drive connected.... I want to see some mobo bios screens before I get to that point. I tried removing the battery just now with the same results. Reset the CMOS jumper a few times... honestly this is ridiculous. Everything is brand new except the ram and vid card and I tested them and they work. Back to my earlier question: could under powering the system somehow damage the mobo???

Go buy a new mobo man, and this time get an ASUS. That sucks... I assumed you were only having post errors, my bad.

I am not aware of cases that undervolting damaged the mobo, unless the PSU spiked in the process to attempt to keep power up. Does the tigerdirect store offer the possibility to test your MoBo? (esp. since you dropped ~$400 on them recently, and if the MoBo is faulty, you might spend another $100 or so).
