Erm.. yeah. Some of you will know that the asetek waterchill cpu block doesn't fit the NF7-S particularly well. I thought I'd read somewhere that bending the cylinder things next to the cpu slot slightly would be okay. I'm not even sure whether this is the problem or not... Anyway, I set everything up, double checked everything three times, and tried to boot up. System boots up for one second, pump starts pumping. System shuts down after one second. No beeps, no flashing lights. When I try to turn it back on, it won't do anything. So unplugging, waiting for the mobo light to go out, and plugging back in, it will turn on... once, again for a second. Not again after that (unless I unplug again). I've checked everything. All the components, RAM, cpu, pci, agp, waterkit. Nothing has gotten wet. Please Help! I really hope I haven't poopied my mobo...
Right... firstly... those cylinder things are called capacitors (if you're interested) and it's only really ok to bend them a really small amount if at all.... a lot of manufacturers solder them in with very little room top side of the mother board to bend and such... so I'd check each on to make sure you havn't broken any capacitors... secondly... have you checked the CPU is oriented correctly (ie. pin1 of the CPU is aligned with the marker) and that the RAM etc is seated correctly...
I checked the cpu and ram as soon as it didn't work :/ The capacitator (thanks ) was standing a little off the board, but I erm... pushed it back in and it looked okay.. probably isn't working okay though now. I cut one of the wings from the cpu block to allow room for the capacitators without bending them. No avail though.
Have you tried running the system with just the bare essentials, (ie, CPU, one stick of RAM, GFX) and have you tried going back to Air cooling while you test this.... As I said, it could just be the way the componants are seated...
It's ok.... just be sure to check seating of RAM ang GFX cards, and make sure the CPU is in right... Hope it's all ok... good luck
No luck Everything is seated absolutely lovely.. double check the cpu, tried with aircooling. Removed Ram, put it back in. Tried with another different stick. Tested to see if mobo is shorting through the case, but isn't. GFX is in fine, reseated. Still no luck. Feeling a little defeated atm
Unless yo went snapping off a bunch of caps, I wouldn't be to worried about them, most mobos can operate with incapacitated caps. Still, I wouldn't advise breaking them First things first: CLEAR YOUR CMOS. Move the jumper to the discharge position, and wait a few seconds. Check your manual, it should be near the battery. The CMOS must be cleared when you first setup a new rig, or change any major hardware (like CPU, RAM, etc)
I already have done a few times :/ Plus, it's not particularly new board. It was working fine around 6 hours ago with the spec in my sig, minus the waterchill plus a coolermaster xdream. I'll check everything. Again
My advice would be to go over allt eh caps you tried to move around, and try to wiggle them (very very gently) to see if the leg(s) are loose, and maybe get a connection. If you do find that one or more of them are indeeed disconnected, and you have balls bigger than all outdoors, you could try to re-solder them back in place. I should note, this is a sort of last resort option, as you could b0rk your board even more. So do it at your own risk.
Luckily, I only moved one of the caps (the one nearest the top of the board)... so if it is the cap, then I won't have much soldering to do (if I need to solder). If the board is broken, then I have a spare A7V8X-X in the cupboard.. Not quite as special though
You said you just installed watercooling right? It might shut down because there is no fan plugged into where the CPU fan is supposed to go. The board automatically detects this, and it shuts down to stop the CPU from overheating. Since you need no fan, you must put in a temporary fan in the CPU1 plug, and start up into BIOS and disable the auto-shutdown feature. Hope that does it.
Just wondering if you have one of them mobo's that will not boot with a fan plugged into the CPU header? You could try plugging a fan into it and booting? EDIT : j`w0n beat me to it
I tried with fans plugged into all of the fan connectors on the mobo, still no party :/ I've re-set the CMOS a number of times, replaced the mobo battery, tried it with another cpu, checked the power switch isn't sticking (by "hotwiring" the mobo), tried with another psu, applied a bit of pressure onto the capacitators to see if their contacts are skew-wiff... May consider taking the soldering iron to it tomorrow :/
It died right after th pump started? Was the pump's power supplied from the PSU? I would start there, motors are not nice to power systems, especially DC ones. Unless you really forced the cap around, it should be fine. If it were broken, I wouldn't even suspect a boot up. The caps are there to make the circuitry that supplies power to the CPU work. Breaking one would either result in no power to the CPU, or burning it up. The PSU can be tested without using another mobo. Whip up a quick LED circuit that runs off the 5 or 12 volt lines, then short pin 14 to ground. As long as that pin is held low, the PSU will run, and the LED will light.
Nah, the pump uses a hermaphrodidic plug, so it's running off it's own power source afaik. Gonna do some more testing today and see what happens. Thanks again, guys.
Think I've found the problem now. Thanks to your post, Splynncryth, I've come to the conclusion that it was actually a capacitator that I had knocked out of place. Therefore causing the cpu to somehow "blow". What I didn't test was whether the cpu would work on another board. I did now, and it doesn't work. So both mobo and cpu are now poofaced because I gave a capacitator a nudge out of the way. Off to cpucity I go then...
