Now, I had recently just got a new DVD-ROM drive for my computer and installed it properly, it is on the master slot and the master drive. Everything was fine. However, after I installed this component, my computer just begun crashing, out of no where. This pissed me off so I took the power off of the dvd drive and put my computer back to the way it was, however, it kept on doing so. One thing I observed was that immediatly after it crashed, power would still be going to the motherboard, however nothing else would have power. This kind of confused me at first, though, another thing I had observed was that right after it crashed, and I rebooted it, the computer would crash again, just much faster. This led me to believe it was heat related, possibly my CPU was over heating. This was going on until a week or so ago my computer just will not boot completely up. I turn power on, however nothing is displayed on my monitor and it goes into power save mode (you know when it goes from the green led to a yellowish-brownish led) immediatly during boot-up, as if nothing was happening. I have had this problem before, it was that the graphics card was not properly seated, or it was loose. I took the graphics card out, problem solved (the first time this had happened). Now, though, I tried it and nothing, it still does the same thing. Another thing I noticed was that the hard drives were getting power non stop, I can leave it running for a good 15 minutes and the hard drive power light is still on. Not even at bootup before was this still on. Again, I had thought that it was heat related so I thought I fried my CPU. I did a little background check and I had all the symptoms of electro migration. So, I figured my cpu was done and I purchased another off of ebay. It is a brand new CPU, in unopened box, so I figured it was good. I installed it, put the heatsink back on and tightened everything up. I then started my computer and still, nothing. The monitor stays black, it goes into power saver mode and the hard disk is getting full power. This should not be happening, at all. I was wondering if any of you have had this problem before, and/or if so/not, what would be the fix? Quick note, I built this PC from scratch, and have never had a problem like this before (except when I first had started it and the video card wasnt properly seated). Another quick note: Before when the gfx card wasnt correctly seated, the bios would beep at me, its own beep code for video card not detected. This is how I knew it wasnt properly seated. Now, the bios speaker does not beep. I hear nothing besides the computers power being ported through and the LEDs for the hard drives lighting up. I was curious if I could have fried my motherboard? Does this sound something like that? Yet another: When the computer first started crashing, it would completely power off, I would have to hold down the power button for a few seconds until the power LED would go out. However, after I would try to restart it after, it wouldn't completely turn on. I had to turn the power supply off in the back, then restart. :ff: (no pertinance, just was funny, I have never seen that emoticon before)
Check the power cord and outlet. Check the power supply's connector to the motherboard. Disconnect and reconnect to be sure its firmly connected. Check the power supply. If you can test it in another PC, try it. Check the power switch on the PC's case and make sure it's properly connected to the motherboard. Try shorting the jumper pins that the switch uses to power on the PC. If that works, the switch is bad. Make sure the motherboard surface is not making contact with the metal case (except at its mounting points). Take the motherboard and power supply out of the case and place them on a non-conductive surface (wooden table, etc.). If it boots, something was probably shorting out in the case.
Thanks for the help, but that seems like a generic response from a seperate post. None of those have worked. I have two power supplies, 350w, and a 500w, I had the 350w plugged in but started crashing so I disconnected everything there and hooked up the 500w to accomodate for extra power usage via the dvd optical. However, same symptomes. Power switch is good, short checked it, completely fine. I attempted a coldboot on a wooden table, still same thing. Severly depressing

The gradual deterioration leads me to believe that this is a common power supply problem. My computer did a similar thing about a year ago. Very likely that if you've used the power supply that came with the case then its a cheap one, which has failed. Its a very common problem with cheap PSU's, a friend experienced the same as you. What model is your PSU? Watts aren't he only thing to consider, its also about amperage, and the quality of the brand.

Well, at first I thought the same thing, so I switched out that power supply with another one that I have. The same thing happened, nothing. I changed it only after the computer wouldnt boot up at all. Is it all the possible if I fried the southbridge on my mobo? The one that came with the case (350w) was an antec. The 500w one I purchased from compusa (and it bears their namesake all over it's box) so thats all I can really say for it. I cant imagine both blowing within the same hour of each other. <e> Well, I just rebooted it, and everything, EVERYTHING has its own power. There is just absolutely nothing going to the screen. My dvd-rom drive, my cd-rw drive, both my hard drives, everything. So the power supply is good. However, something must be either A. Wrong with my BIOS, or B. My graphics card took a shit. I dont think its B because my BIOS would give me an error that it cannot find it I WOULD THINK. Im getting another motherboard with *gasp* onboard gfx. So when that comes in we'll see if the onboard works. If it does, we will switch to my graphics card, and disable the onboard. If that doesnt work then we have isolated the prob. If it DOES work on the new mobo, then it must be the BIOS. Hmm, I honestly hope my graphics card isnt blown. Btw, my power supply currently is Antec at 21Amps, so I am almost positive everything is fine there. Could this be caused my a dead BIOS battery? Or could it be caused my a graphics card malfunction? Thanks for helping, Bloodrager
