At first my computer had no power at all so I bought a brand new power supply unit and installed it. Now it's got power but there is NO POST beep and nothing displays on the monitor. It just won't boot up. I've reseated the ram, the psu cable and ALL of the drive cables (including power cables). Even tried a new monitor. I've reseated (and even changed) the CPU and it made no difference.

I checked the motherboard and it appears to be alright to the naked eye.

Since my computer is Intel powered I replaced the old psu with an Intel/AMD compatible psu. The old one was 250 watts and the new one is 350 watts. I actually took the old psu with me so the "techie" could replace it with the appropriate one. I also have a Super-Flower psu and I connected that also in order to "eliminate possibilities". Nothing changed. This was the second working psu I tried. Keep in mind. the old psu didn't even supply power to the computer at all.

The fans and lights all come on (they did not come on prior to the new psu). The hard drive light stays solid, and does not blink like I assume it usually does.

I reset the CMOS by removing the motherboard battery and unplugging the computer from the wall. You got it..............nothing. I also tried two different hard drives...and still nothing.

Any suggestions?

Hi,

Why not back up a little bit and talk about your motherboard, your CPU, your video card, what drives you are trying to run. Also, tell us what the techie sold you. Tell us what brand (you said 350 watts) of power supply. This type of information should help us to know more about what is going on with your computer.

The techie sold me a "Switching Power Supply" (a Macron MPT-350). I also used my other new power supply unit and it is a Super-Flower 330 watt unit.

As for the motherboard I have no idea, nor do I know how to tell the type of motherboard it is. I do however, see "PC Partner" on a few of it's components.

The video card is a ATI Technologies card (does that sound right?).

In the process of trying to get the computer to boot I disconnected ALL the drives and and tried to boot the computer without any just to see if I got a POST beep. I eventually reconnected them one by one.

Hi,

I am posting a list that I copied from linderman a few days ago, so you can see the quality of the supply that you are talking about. I do want to make sure you know this is linderman's chart, so give the credit to him for posting this information, but I lost the link where he posted it, so will send it this way: (In the meantime, will try to find the link he posted it in so I can send it that way)

If possible to return this to the person who sold it to you for a refund, I would do that and purchase a quality power supply of a larger size.

Also, if you will run this free program called Everest, it will tell you everything you need to know about your computer so you can provide us more information:

I don't even see my power supply listed there. Mine is a MaCron not a Maxtron. I looked everywhere on the box and the PSU to see if it in fact was a Maxtron and I could find no such thing to link the two together.

Remember....I also used a Super-Flower which I have powering an ideatical computer (thats where I'm getting all the replacement parts from) and it runs fine.

After all this it's just got to be the motherboard. I'll be checking out prices to see if it's even worth the expense.

Thanks for your input.
