I just bought a new computer and it will not turn on. I can only get the power light to come on when I hit the button but nothing else seems to work.

ASRock K7VT4A+
AMD Sempron 2400+
GeForce4 Ti4800SE AGP 8X 64MB
Casecom 11-Bay ATX Side Window Case
SUN PRO 300W P4/AMD POWER SUPPLY
256MB PC3200 DDR

Now I had them install the CPU and RAM and test it before they sent it to me. So all that should be fine. I tried a different power supply and that did not seem to help. Not sure what to do. Advice?
 
Dis you try this outside the computer case?

Whats the true capacity of your power supply? What I mean by that is not whats written on the side like "400W" I mean what are the amperage (A) specs for each voltage on the side of the power supply for:
3.3V = ?A
+5V =?A
+12V =?A
+5VSB =?A

These are the minimum recommended in the AMD desktop builders guide circa 2002 for a certifed 300W power supply.
+3.3V = 28A
+5.0V = 30A
+12.0V = 15A-18A
+5VSB = 2A-2.5A
 
I figured it out. The case had built in spacers made from the case. Therefore the power was being grounded by the case so it wasn't working. I had to glue spacers down on the case for it to work right. Word to the wise, the case I mentioned above is terrible. I wouldn't suggest it to anyone. Thanks for the advice though.
 
the case is supposed to ground... you probably had a short somewhere, and hwen you took it out of hte case and messed wtih the standoffs, got rid of it.
 
you're lucky that you didn't short out the entire board. I did that once a long time ago...I missed one standoff and ZAP! went the mobo :eek:

Please do not respond to my post saying that is not how I fixed it. I am aware how I fixed it and I wanted other people to be aware of it too. To telling them is not what happened does not help others if they run into the same problem.

please dont not state inaccuracies. the screws and standoffs, as well as the I/O board are designed to ground the system to the case. what are you talking is NOT a ground, but rather a short - where one of hte standoffs was hitting hte board where there wasnt a hole.
