My computer won't start. Power supply (ttgi 450ss) has a blinking green light and the power supply fan starts when plugged in. Motherboard (asus m2npv-vm) has a green light illuminated between the pci...


See if you plugged in the 4 pin power connector on the motherboard besides the main power connection on the power supply (usually black colored and its a plastic 4 pin connector)

Try another power supply if all else fails. If new power supply does not work with this unit then its a motherboard which is blown and motherboard needs replacing.

Hope this helps

System wont turn on and there is a solid green light at the top of the mother board of my gateway 310 pc replaced batt on motherboard and it still wont turn on.


hello, this be caused by several things , i am assuming your are okay with opening up a PC since you have already changed the onboard battery.

here are few things you can try to further troubleshoot:
1: though the ligh on motherboard is on, power supply can still be faulty, so lets test that with a paper clip trick,
follow this link there are pictures and very clear instructions: http://www.ehow.com/how_4732521_test-desktop-power-supply.html
if power supply is bad, well then you know what to do... change it.
if the power supply is good:
2: remove all the RAM (memory) chips from motherboard and plug the power cable back in and observe the response (you may or maynot hear THREE beeps) now plug in memory chip and try powering up and try with one chip at a time...if PC boots up with any of the chips in it you knkow you have a faulty memory.
if that didn't work:
3: with everthing put back together try disconnecting just the hard drive and power it to see if you see BIOS screen.
if not:
4: many time this worked for me with Gateway PCs, reseating CPU in its slot but only do it you feel confident doing it because you can end up with a GIANT door stop if any of the pins on the CPU are/is damaged.
you would need some thermal-paste to go back on between CPU and heatsink.
if that didn't work..i think you are up to buying new PC.

let me know if you need more help or not clear about anything...
good luck

P5NT won't boot


I went throught this and it is really silly. The P5N-T motherboard has a problem with some of the new energy efficient CPUs. The fix was to insert an older CPU and upgrade the bios and then it would recognize the new CPU. If you happen not to have an older 775 CPU laying around (most people do not), it might be easiest to return it and get a different board - or maybe the store can upgrade the bios for you.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
