OK, this one has thrown me for a loop. A buddies computer stopped booting for him so i said i would take a look at it. The BSOD that its getting (even when trying to boot from a bartpe cd) is STOP 0x000000ED UNMOUNTABLE_BOOT_VOLUME (with some other codes in between that weren't relevent. The strange thing is, it would still do it if i tried to boot the bartpE cd without a drive hooked up. All the drives used are known working drives and a bootable linux distro on a thumb drive works, as well as an ubuntu live cd. Any ways, I think i have come to the conclusion that the hdd controller on the board is fried. I was then just looking over the board, just checking out all the components and such, and cam across this: Btw the board is a Asus p5ld2-v. Could this possibly be the cause? (Doesn't make sence cause the board just recently quit after only about 2 years.) Or do you guys (and gals ) think it was "designed" this way? (read: designed being last minute fix before leaving factory) Any ideas?
That doesn't look right at all. Judging by the other unsoldered bads still having solder on them, it looks like a piece has fallen off and shorted.
But what doesn't make sence to me is the fact that the board worked for 2 years already. Also it just seems odd that the smaller resistor is "attached" directly to the one pin of the other resistor cluster. I am debating on trying to resolder them to the board (if you seen my Tinytux project log, you should see it will be easy for me). Just not sure if i should heh .
It could be anything, if it's a component that can get hot it may have melted, dropped down and as the solder cooled it "attached" itself to the parts. Try to flash the BIOS first, then try that component, then get a new board/persuade an upgrade
well as a electronics engineer. this looks like a normall repair to a board, in order to fix somthing. the question i would ask is has the joint between the two 0 ohm resistors become dry, and is it open circuit. check the resistance over the two resistors, it may be the issue ps there is a lot of scratching arround these points on the board, have you done this trying to fault find, or was it delivered like this, because it is not somthing i would expect a manufacturer, or repair house to do.
No, have done nothing as of yet. I did try to flash the bios via floppy .. but it didn't work for some reason. not sure why but will look into that. Also there is no resistance between the two and it still has continuity.
The chip in the picture is the clock generator, so that would certainly cause instability. Seeing at that is a 0 ohm resistor, I would say something got hot and the part moved. All the reworks I have ever seen (and I have now seen a lot) where such a connection should be needed involve wires, not SMT components. It looks like the part came from the pads to the right of the 0 ohm the suspect part is connected to. If the right hand side of the picture is 'up' then this is totally plausible. A better question is how things got hot enough to reflow the solder. Something else could be wrong is that short didn't do any damage.
