New motherboard and no video after running fine

[nimchip]

My brother recently bought a new MSI K8NGM2 and an AMD 3200+ Athlon 64. I assembled the thing last week and it was up and running fine until about friday when there was a blackout. When you attempted to turn on the PC it had no video and the PC Speaker sounded like a lot of static. I quickly tried to "discharge" by unplugging the power cord and holding the power button. I also tried reseating everything. After all those attempts I removed the Motherboard and RMA'd it.

Fast forward today, I installed the new one and it was up and running for a few hours. I left it on while it was updating Windows. When i go to his room i find out that his pc is on the startup memory/cpu/hard disk detection screen and it has "jaggies" or something similar to what happens when a vid card Fan stops working. I restart it and it has no video. I'm convinced that its the motherboard again (he uses the onboard Geforce 6100 north bridge as video). Like the previous time, there were no beeps or so at start up.

What could cause this though? It has happened in two different occasions with the same brand new board. Any ideas?


It also has 2 sticks of old PC2700 ram, one 512 mb and another 256mb. One hard disk 120gb Western Digital, one dvd/cd-rw combo and a floppy drive.

Sorry I forgot to adds that there were of course no beeps. I will try reseating the ram with this one later and will post if nothing happens.

Is your PSU adequate for this rig, say, at least a 350 watt quality unit? (I'd also drop down to a single stick of mem in an approved slot while troubleshooting...)

Also, check to make sure your case standoffs are correctly positioned for your mainboard, with absolutely no extras....

WHile trying to get at least a POST display, disconect all ribbons, SATA connectors, and pwr inputs to assorted drives...

What size/make is your power supply, as obviously, not all are created equally.

 

[nimchip]

400w max +5V/30A max, +3.3V/28A max, +12V/0.3A max

i will check for extra stand-offs though, and try all you mentioned.

 

[nimchip]

it had an extra stand off, unfortunately it didn't fix the problem... probably what shorted the motherboard or something?

I will disconnect stuff now and try for a display like you said.

 

[nimchip]

I tried disconnecting every IDE cable, sata, everything off the motherboard except power and ram. There's still no video.

I think i'm gonna RMA again and probably get a different motherboard.

I'm not too sure whats going on but I think you may need to get a better PSU like 500W+ for example. Cuold be an overloaded power supply. (heh a bit like my 350W+ PSU already making horrible sounds,could it be possible failure)

Hey I happen to have a similar prob but I'm not sure If my PSU's overloaded.

My PC's got:
AMD Athlon 2600+ CPU (1.91GHZ but sometimes OC'd to 2.1GHZ)
Asus motherboard with onboard graphics (GF4 MX)
512MB RAM
3 hard drives
1x120GB
1x200BG
1x300GB
DVD-Writer
Fan controller which uses up 20W max
My power supply's making horrible noises, Can u guys suggest whether my PSU's overloaded? It's a 350W Antec, 2 fans. Any suggestions would help, thanx.8)

 

[nimchip]

well I disconnected all fans and everything, left only the motherboard power and cpu fan etc to see if I could get a start up screen and it didn't happen... I don't think the PSU is the problem.

 

[nimchip]

Well you know what.. someone in another board suggested that my power supply might not be offering enough juice for the board. Doesn't make sense since I disconnected everything and it didn't work anyway. Just in case you guys agree or something the PSU is a generic (i know they suck) 400W PSU with +5V/30A max, +3.3V/28A max, +12V/25A max.

From what I read in this forum it's NOT the psu. If there's no video coming to the screen and you did all the tests what I would usually do is replace the mem, then replace the CPU. if none of these fix the problem then it's the MOBO. But if it is fixed then whatever part you changed will be the problem and just replace it. Hope this helps

 

[nimchip]

Hmm thanks for that. The ram is old so it may be the ram, however the CPU is brand new so I don't think that's it. Besides both of these were working fine on both times until the poop hit the fan on both accounts. I'll check it again today but I'm almost about to RMA again before the time expires.

It DID have a standoff that wasn't aligned with the board. Perhaps it shorted it on both times. I can't understand why a board would give out so easily though.
