Symptoms of an Asus

Re: Symptoms of an Asus

preheating the board (hairdryer) and a lot of fresh solder (with flux) usually help.

The giant gound traces just suck up the heat from the iron, making it hard or almost impossible to solder normally. Temp just doesn't go high enough.

Motherboards are thicker than most PCBs.

Need an iron with more watts and a better recovery time.
[When you first touch the tip to the work the heat gets sucked out of it. Recovery time is how long it takes to heat it back up.]
Most people are happy with 50-70 watt irons.

Re: Symptoms of an Asus

Well the computer is back up and running, i put in a used board after butchering the other one with a low watt soldering gun. I'm sure it was fried anyway but this mark was before i even started to recap it. I thought 30 watts would be good enough but apparently not from that weller from radioscrap..

So this was what i was talking about the brown spot on the back of the board which just didn't look right at all. Also like I mentioned my brother had the same board and the exact same symptoms then dead.

At least now with the new cpu cooler it's at 37 C instead of almost 70. I have some questions about speedfan though but i'll ask in general computer.

I circled the brown part and it wasn't dirt and was cleaned before that. Knew it wasn't the PSU or bad ram and works fine now cept for readings from speedfan which show temps 105 c from power....power what? and 105 from AUX...again auxilliary what? All other readings show cooler than normal.

Whatever is on the other side of the board was getting hot.

Something next to the ATX connector - some mosfets possibly?
More pictures of butchery! It may still be savable.

Re: Symptoms of an Asus

They might be OK... I've had some P5L-VM 1934 with blown KZG and a hot mosfet for/in the circuit of the SATA controller. They work OK after a re-cap, but disk access is a bit slow, might explain why. When the cap fails, SATA disk access is gone completely.

Re: Symptoms of an Asus

I've had these problems with two of my customer Intel socket 478 ASUS board, with the same CPU spec, both of em using Celeron. I can't remember the mobo series but both of em are the same and had the same problem. They keep BSOD, and the problem are the CPUs, coz when i swap it with another Pentium from my other customer, it would boot up fine and i can start to reinstall the Windows. So i think perhaps the Clereon is a defective tray CPU or maybe there's a compatibility problem with it and the mainboard. So try to use a different CPU for a few hours, if it works then its the CPU.

Re: Symptoms of an Asus

brownish PCB around the VRM (voltage regulator) area seems to be "normal" for cheap POS asus boards.

Brown PCB spots are apparently normal for Deer PSUs, lol.
