Hey guys,

I decided to clean my PC out today, blast the dust and remount the HSF. When I took my S1283 HSF off, the back plate on the mobo fell off, the adhesive was not sticky anymore....so I stupidly super glued it back on to my mobo. Hooked everything back up, and now...when I turn it on, it turns on, all fans spin/lights light up and then immediatly turns off and it goes into a constant on/off loop. No error beeps, just fans spin and then looping off/on.

Specs:
Cooler Master HAF 932
Q6600
GAP45-UD3P
550w corsair HX psu
4850x2 2gb
8gb g.skill ram

My theory right now is that it is shorting out right now, either due to the super glue possibly being conductive, direct contact of back plate and mobo, or there is a screw in there somewhere.

So far, I have removed the cmos battery, ram and vid card...same results are received. I'd like to avoid taking it completely apart and out of the case, but will if I have too.

Thoughts?
 
Go through your list.

I'd bet on conductive superglue being the culprit, though a backplate shorting something off is not unheard of.


Also... you did unplug your fan before airblasting it, right? Fans in reverse generate electricity... and that can do some work.
 
I did not unplug the fans before blasting, but I doubt that is it.

So, here is what I will do....remove everything from my case and try it outside of the case, if it still does not work...

1) How do I remove a super glued backplate without fucking my mobo?
2) How can I remove super glue?!

Why god why! Think its permanent damage?
 
lol.

Anyhow, if superglue doesn't come off with isotropyl alchohol, I don't know what else will do it. Ripping it off will just... rip all that SMT off. (surface mount tech).

When you try it outside of your case, use plastic standoffs, if you have them. Otherwise, set it ontop of your mobo box.
 
Took everything out of the case and even tried a different PSU....same results.

Taking it out of the case = unscrewing everything, plugging in essentials only and holding the mobo in the air by the HSF!

Nothing in the case was touching it AT ALL, so it must be my ingenious super glue back plate
 
I really wouldn't use any kind of alcohol for this, seeing as alcohol forms an azeotrope with water, which may in turn wreck the mobo even more. You can get pure dry alcohols, but I imagine they'd be kind of expensive. I've never done this sort of things before, so I don't know exactly whether what I just described will happen, but if I were you I wouldn't risk it.
 
Well, I was able to remove the back plate....I was careful not to use too much super glue at all. I cleaned it up as best I could. However, my issue persists. It looks pretty much impossible to completely clean off all of the adhesive and crusty glue from the back plate and mobo.

Think it's toast? :-\
 
Press the power button (or short the correct power button pins) and see :D.

We're waiting.

Sometimes, it just takes a long POST.
 
Yep, same stuff.

Turns on, fans spin, mobo lights up, video card lights up, turns off, turns on, turns off, turns on, turns off, turns on, turns off, turns on, turns off, turns on, turns off, turns on! No error or post beeps at all.

I'm starting to think the motherboard is fucked. :-(
 
Did you put TIM on the CPU? (I'm assuming you did).

If not, it could be overheating and shutting down?

But at any rate, try the bare min:
1 stick of RAM (try shifting slots, too)
1 CPU
1 GPU (the lower end, the better)
don't bother with HDD, as this is a POST test, not a boot test.

Also, anything to reset via jumpers? Loose jumper caps, maybe?
 
Yeah, there is TIM all over it. Perhaps too much? Is AS5 conductive?

Don't think there is anything to reset via jumpers on the GAP45-UD3P, cmos battery generally handles it.

Let me go try bare minimums....

AS5 is barely conductive, but since no electrity goes through your CPU/HSF anyways, it's moot.

I use it for everything, so no problems yet.
 
Here is what I did.

1 Stick RAM > tried all 4 slots individually
Plugged in 24pin and 8pin psu connectors to mobo, disconnected all sata/random cables, no video card

Powers on, powers off....never ending loop of doom! I also tried outside of the case, so I don't believe there is a short in the case anywhere.
 
Look at the board closely... anything wierd? Sorry, but after this, I'm lost, too.

(any beep codes?)
 
Nope, all of the lights on the board look totally normal. No beeps, no nothing. Just a continuous loop off on/off.

It's not making any sense anymore, and honestly...the only that has changed *is* the super glue + back plate combo. I'm tempted to try turning it on with no HSF/back plate...but thats bad for the proc, and it wouldn't stay on anyway.
 
Lesson learned. Buy a new board. Be more careful with your parts. There is absolutely no need for the backplate to stick to the motherboard. Install the CPU and HSF outside of the case, and make sure that backplate is insulated from the motherboard. You can use liquid electric tape if you no longer have the plastic that came with the backplate.
 
Yes, lesson learned indeed.

New Problem! I got a new motherboard tonight (same one). Hooked everything up, turns on, post beeps, all good. The Gigabyte BIOS flash screen is very grainy and wavy, after that stops I get flickering green/black bars everywhere and gibberish hexadecimal code.

I KNOW my video card was working before my previous mobo fried etc. I have a 4850x2 and get no video in 3 of the DVI ports, and the 4th port gives me this green/black bar shit. Could it be this new mobo being defective, or is my video card just fucked now?
 
Video card. I'm sorry.

But that is the tell tale sign of a RMA worth card.

Does the mobo have a video output?
 
Nah, no video output on the GAP45-UD3P.

So, here is my issue.....if the video card got fucked due to me frying the mobo with super glue....what else could be wrong now? Could my proc have been damaged? Hard drives corrupted? Sigh....this is terrible!
 
HDD/CPU, maybe not, as the system will post.

The GPU may of been on it's last leg, anyways.

To really confirm, test another GPU out on this mobo. Or test the GPU on another mobo.

I don't really know how Gigabyte mobos fail, so maybe, just maybe it isn't the GPU. But far more likely to be.

A cheap, 20USD card will do (I have one around my house, always there, just in case I need to test something).
 
Going to try and RMA the card with Saphire....

But, as far as the HD's go...I was able to see some form of windows boot error saying something got corrupted and it wanted my installation disc etc. :-\
 
Would anyone else have any suggestions, aside from it being the video card? I am a bit weary of the mobo as it was a "reduced item" at Fry's and was only 119, compared to the usual 134 for the UD3P. Thinking it was a return, but....no idea. :\
 
....my friend had fried his motherboard a few months back by shocking it somehow. Opened his case to clean out all the dust, but than went to turn it on and similar issue arose : (

Yes, it was a returned item. Since ESD can have a latent affect, there is no way to tell if the board was or was not exposed. Anyhow, if the board is working fine after you get your RMA'd vidcard, then there's probably nothing to worry about.
 
Sapphire won't fucking RMA my card as I have no purchase receipt.

Gonna drop 20 bucks on a shit card and test. If it works, anyone have any recommendations for a decent gpu that is similiar to the 4850x2 2Gb for around 150?
 
I'm sorry to hear that. Sapphire ranks prettly low on my list (again, from experience) because of their horrible warranty.

You cannot find a card equivilent to that (unless if it's [H] FS/FT) for 150... I know a few folders (if you wannt help out the cause) have 9800GX2 cards for roughly 180USD (eVGA/XFX). It's all up to you.

5770
http://www.newegg.com/Product/Product.aspx?Item=N82E16814150447

XFX uber alles for ATi. The only real warranty, well... ASUS, MSI, and a few others count.

It's 180, though...

While it isn't a 4850x2, (it's more like a 4870), it will do the job just as well.

If you want nVidia alternatives, there is the GTX260 from ASUS
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121337
170USD, 150 after MIR.


Also... where did you buy the card from? NewEgg allows you to reprint old reciepts.
 
Print ALL of it. Yes, I used my Invoice as a reciept for Sapphire (from NewEgg).

They still (to put it very nicely)-ed about it, though. Got my card back after 2 months.

EDIT: and it was working. Still, last time of Sapphire for me. (about... 2 weeks of no real communication from them, and I have to pay shipping, and.... it wasn't cheap to ship thrice)

Sell that card, and spend the extra cash for a decent, newer card with a real warranty.
 
It took 2 fucking months for the RMA? Jesus christ, I'm SO selling it when I get a working one back....thanks again for everything mang!
 
2 months.... and 3 times shipped, round trip :(

XFX... haven't had to do it yet, but nothing but goodness from [H] users.

same with eVGA

BFG seems good, too. They even have a forum rep here on [H].

Sapphire... too cheap for their own sake.

Thank you, and I wish the best of luck to you!
