So... I'll try to be both thorough and as quick as possible, I would really appreciate some advice on this before my impulsiveness kicks in and I do anything rash. This is actually quite an old computer I had lying around (thank god)... a Pentium 4 2.53 ghz, FIC VI3L Mobo, Radeon 9700 Pro AGP, 1GB DDR PC2700 RAM (512x2), Thermaltake TR2-430W power supply, two hard drives, both connected by IDE
Thing is, I decided to give it to my nephew who could use a computer. About 2 weeks ago I verified that it still worked, cleared all of my old stuff off of it, etc.
It needed a new case because the old one was missing a side and I didn't want to give it to my nephew in crap condition. So I ordered a $25 or so Rosewill case off of Newegg.
I transferred everything over, and tried to boot several times. Each time, it would stay on for the same amount of time and then power off... about 3-5 seconds.
I used the troubleshooting sticky at top of this page. Realized I forgot to hook up the mobo speaker. So I did that, and I realized that it was actually getting to POST, and then shutting off IMMEDIATELY after (one short beep). However I never got any video on screen.
Upon closer examination, it turns out I did forget to hook up the Molex power connector to the Radeon 9700 Pro. I forgot that such an old card needed to draw power from the power supply. So thinking I may have fouidn the problem, I hook that up, and I boot the computer.
This time, it doesn't even stay on for mroe than a slpit second. I also hear a SPARK sound, and THINK i smell a slight burn. I examine everything, don't see anything, and my girlfriend convinces me it was in my head because she's cooking and that could be what I'm smelling. Oh well.
Either way, now the computer isn't really turning on at all. No fans. Just a faint light coming from the power button when I have it in the "on" position.
Now I think it's probably time to troubleshoot the power supply. I have an old crappy pwoer supply that came with a case I bought that I never used sitting in the closet. So I take out the Thermaltake, and put in this crappy looking 500W Raidmax power supply. And then all hell breaks loose.
The computer isn't on for more than an instant when I see some smoke that SEEMS to be coming from the video card. I can't remember if I shut the computer off right away out of panic or if it shut off itself; either way, it wasn't on for long. I've never seen anything like that happen.
I examine the video card, I examine the AGP slot and the mobo around that, everything looks fine, no burns or anything. I take the video card out and leave it out, I then intended to test the motherboard as advised on this forum, by removing the RAM and booting to see if I get the expected beep codes. Since the video card was (presumably) just smoking, I take that out as well.
So I boot up with only the hard drives, CD drives, motherboard, and CPU/HSF plugged in. No RAM and no video card. This time, smoke starts coming from what looked to me like the back of the hard drive!!! Hard to say, because once again, I turned off the computer quickly.
I don't really uinderstand electrical science or components, so I don't really know what to make of all this. These are the main questions I have:
1) Is it more likel that the smoke was coming from my motherboard, or the components themselves? If it can be the components, what could cause both my video card and hard drive to start smoking???
2) Is it dangerous to investigate further? My next idea is to take EVERYHTING out except the heatsink/cpu to see if the motherboard/power supply/cpu work on their own, but thsi definitely isn't worth starting any fires over. The smoke had me a ltitle surprised
3) If the motherboard or power supply was the problem and the cause of the smoke, could it have damaged the other components? If they're damaged, is there any risk in trying to reuse them in another computer that I care about? There were some expansion cards in this system at the time that I wouldn't mind salvaging
4) any ideas as to what caused all of this? Unfortunately, I didn't test the computer immediately before I transferred it to the new case, but like I said, everything was working a few weeks ago.
Kinda sucks. My ltitle nephew was really looking forward to this computer, but unfortunately I can't afford to get him a new one, and from looking online it seems like buying new components for the pentium 4, ddr1, IDE generation isn't very cost efficent at all. Plus, I don't even know what components still work and what not so I'm very wary to begin replacing anything
Any advice, insight, or comments will be appreciated!
P.S. When it wasn't booting, I checked for possible sources of shorts to the motherboard like those brass things that go in the back, but I didn't find anything out of order. It's possible I got a couple of the events above mixed up in order, but that's the best I could remember
