Completely Dead System. No Power Up.

[smokinyoda]

After a recent motherboard/cpu upgrade I have experienced a major problem. Got a new Powercolor Gameboard PVK7 VIA Apollo KX133 motherboard and an Athlon 750. After installing would run fine just wouldn't start back up. Would have to push the power switch repeatedly to get to come on. Now it won't come on at all. No power on of any kind. Just like it was unplugged from the wall. While it was running would restart fine. Just did not want to cold boot. Also while running no problems even on graphic intensive games. Bought a new 350 watt P/S thinking my 235 was to weak and still no luck. Have now stripped it down to just mem, cpu, vid, and MB. Even pulled out vid card. Figure its either the board, cpu, or P/S. Any easy way to check? Will a good board at least allow the fans, lights to come on if I took the cpu out? Bought the power supply included with a case off eBay. Was advertised as Athlon compatible though did not see it on there site. It's a Codegen. Have given all info I can think of. If anyone can narrow it down please help.

Even tried to unplug memory but made no difference. So now I have a completely stripped down system with only motherboard, P/S, and CPU. Any ideas?

Thats kind of what I was thinking. Guess I will start looking for a new mobo.

I bought one of those boards after 2 weeks it locked up one night never to breathe again..replaced it with a Gigabyte same CPU and been running solid ever since( about 3 months now) Waiting to get a new board I think it is going on Ebay..Im not messing with that brand ever again

To test the power supply (BE SURE THAT ITS UNPLUGGED FIRST for a couple of minutes), connect a wire from the green wire to a black wire. The one's on the 20 pin connector to the motherboard.

After you connect the wires, plug the power supply back in. If the power supply doesn't have its own on/off switch it should turn on, you'll know because the fan will start spinning. If you get power then the ps is good. Be sure to unplug the ps from the wall before removing the jumper wire, this will use up whats left of the juice in the ps.
Make sure you have a good connection when reconnecting the ps to the motherboard. Reseat you graphics card and ram. Now try starting your system. If you still receive no power then the board is probably bad. Powercolor isn't too good a company. I have a powercolor Geforce2 MX, cheap and slow memory on it. And the driver cd has the drivers for the motherboard, audio, and graphics card on it.
You might try a better mobo.

Tried the power supply on a PII 350 and it works fine. Will try the way you suggested now. It wouldn't be the processor would it? Just want to know what I need to replace.

I think it's not CPU. I saw twice the case when the CPU was dead, and you don't have samy symptoms. If CPU would be dead, you could still turn the machine on, but you would have black screen, and nothing would happen.

I have no idea, what could it be, but my suggestion is to check all conections once more. You probably did it, but try it once more, before you buy something you don't need.
