Re: MSI MS-6368 mainboard freezes before loading OS
The snaps were taken before cleaning. i could find only 70% iso alcohol here and it was not removing the flux. A gentle rub with a fine tipped screw driver removed the flux, then i cleaned it with iso after which it looked a lot better. Are via and solder pads one and the same?
Ran some DOS diagnostics from UBCD which turned out OK. i will run some more tests and boot from ubuntu live CD before attaching my hard drive(which is already in use in other system) with Win XP OS to this recapped board for final confirma...Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
On hindsight, a chisel tip iron would have saved me a lot of trouble probably. I don't have any specialized tool to preheat the mainboard. I didn't intend to spend much on a soldering station or other tools as i was not very sure that the issue might be in the caps. Now that the job is completed, it feels like a simple job. But definitely not at that time.
Just to understand,
1) Can anybody tell me what the colour(dark and light green) of protective lacquer on the mainboard signifies?

Re: MSI MS-6368 mainboard freezes before loading OS
It worked !!! It went past the PCI device listing and displayed messages 'updating ESCD' 'verifying DMI' and finally 'disk boot failure' as i had connected only cpu and ram. I was actually shocked more than surprised that the mainboard worked right away after the abuse i had dished out to it. My heartfelt thanks to the forum members especially to momaka. Actually i have another similar mainboard with SiS630 chipset (very poor performance) which i'm using right now. That is the reason i took the trouble to recap this MSI mainboard...Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
The remaining two holes could be cleared by the needle method. But the motherboard is almost confirmed to be scrap now. I have attached some close-up snaps of the cleared holes....Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
Heating on solder side and inserting a needle from the opposite side cleared one of the holes. one down, two more to go. Due to other works, i could not devote much time and finish it in one stretch. To me, it has now become more like finishing the mess i have started in the first place by going straight into it without much practice. Still i continue and thanks to all of you guys for guiding me when i got stuck up. This served as a good experience and even if i scrap the board, i should say i won't feel dissatisfied.Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
1. Flux is already there in the solder and the braid (goot). Is it still needed to be applied separately?
2. I don't know much about ground or power plane. Only that there are solder and component sides and the mainboard is multi-layered. One thing i don't understand is that out of 04 holes (02 nos. 2700 uf capacitors near cpu), 01 hole got cleared fully without any trouble.
3. Will desoldering pump help? I don't want to spend much by the way.
4. I will try the wiggling in method and get a good cutter for the...Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
I was able to remove 14 (1000uf) & 4 (2700uf) caps with a bit of struggle using the wiggle method. Probably damaged some components, don't know for sure. Conical tip worked OK during the component removal. Now the hard part, to clean the holes using desoldering braid. In some cases it worked very well and sometimes it doesn't. There are 03(out of 36) holes remaining to be cleared. Tried 2 or 3 times to add new solder and suck it up using the braid, but doesn't seem to work. Tried to insert a needle also but with not much success....Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
i read that using a lead free solder with a leaded tip iron may ruin the tip. Will the reverse i.e. lead solder used with lead free tip iron ruin the tip too?Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
Thanks for all your inputs. Unfortunately i had bought the iron before seeing your suggestions. It is a goot kx-40r with a conical tip (could not find a chisel tip here at my place). Can i use 5 core rosin leaded solder with lead-free tip soldering iron?Leave a comment:

Re: MSI MS-6368 mainboard freezes before loading OS
I have attached some snaps of my mainboard and capacitors taken from mobile phone camera(slightly out of focused). At the soldering side of the mainboard, the traces are running very close to some capacitor mount holes. If i mistakenly place the hot iron on these traces will it be permanently damaged. I'm not much experienced in soldering stuff, but i can practice with a pci modem card. Should i go for a conical tip or chisel tip iron? I'm planning to buy a standard 40W iron like goot and hope that it will suffice. A slight brownish...Leave a comment:

MSI MS-6368 mainboard freezes before loading OS
After an abnormal power shutdown of my Pentium 3 computer(stuck with it as i had to postpone my new build), the system hangs after PCI device listing. No messages like updating ESCD or verifying DMI etc. are displayed. POST is normal and i'm able to get into BIOS. Tried all the boot sequence with floppy, cdrom, hdd. It is not even reaching the point where it looks for any media to load the OS. All the 1000uF, 6.3V, G-Luxon caps are slightly bloated. I will post the picture of the mainboard soon. RAM and CPU was tested in another system and found OK. Can it be the BIOS got corrupted or due to bad...
