Question about Mach Speed VENOM V2DP Motherboard

1 Answer

Motherboard (MSNV-939) won't power-up

My 680 power supply "blew up" (heard a LOUD POP! followed by a very bad smell) and I replaced it with a 500 (both ATX 24-pin + 12V CPU). Now the motherboard won't 'turn on'. The power supply is "on", the LAN
lights are on, but when you push the "on" button - nothing. I tried changing out the "on" switch to see if that was the issue, it was not. I tried verifying the pin setup for the 24-pin and 12V CPU, no problems there. At one point I had forgotten to turn the power "off" before re-inserting the 24-pin connector, and the system briefly acted like it was going to start, everything would spin up and then immediately stop. Tried this a few more times and was able to repeat. I have isolated the motherboard, still no start. I don't have another power supply or motherboard to work with, so I checked the pin continuity with a multimeter. All the pins shot good to ground on the motherboard, and all the power supply's pins shot good to ground at the terminals (4-pin & 24-pin). I will take any advice on how to proceed at this point!

Well, based on what you are saying, I would say that the motherboard has been affected in some way. Try reseating the CPU and the RAM, then try powering it up.

I assume you have tried with only one stick of ram individually at a time if you are using two to check it's not the ram as one faulty can cause the system to stop. Also assuming you bought the ram from the same place and is compatible with the board. Sometimes people also forget that the processor in some cases has to be powered by the 4 pin plug from the PSU and not just from the ZIF socket that older processors use to power up, so double check the manual. The other main common cause of the this problem is when you are putting together all the hardware onto the board, if you don't protect it underneath it may have overflexed the board and shorted or damaged the circuitry or the bios chip. That's not to say that the motherboard was'nt faulty in the first place.

Plasma made a loud pop then shut off and will not turn back on. There was also a burning smell. Any suggestions on a fix and price is appreciated.


Having similar problem and it sounds like an obvious short circuit if you heard it and can smell it, and it probably took out power supply fuse, so the first thing to do is pull off back of TV and look for obvious toasted components by eye or smell. Capacitors sometimes will pop when they go, and you can see the tops will be bulging out, or black marks, so look and smell all large capacitors first on power supply main board, then check to see if fuse blew. Sometimes the obvious is easy to fix.

Good luck,

Last night I heard a loud pop sound come from my computer and then it shut down. I tried to start up the computer but it didn't turn on. None of the fans turned on either so I concluded something is wrong...


Yes, and the power supply needs replacing.
4 screws hold the power supply to the cabinet or case these are usually located outside visible at the fan vents at the four corners.
