Hi everyone I'm a newbe to this site and they call me Gimp because I have a gimp leg.
I really need some help before I toss this machine in the trash. Here is the situation. My son fried his computer that I built him last year by hooking up a monitor with a bad cord to a new video card he installed.
His dog was chewing on the cable while it was disconnected from the machine. Well being the nice dad I pulled a new ECS-848-p -mPGA socket 478 mainboard and a new Presscot P-4 3.00g processer out of my closet and put it in his ATX box. I also installed 2g of ddr400 dual channel memory. I PLUGGED IT IN AND NOTHING HAPPENED. I checked the PS by jumping the green and black wires on the power connector. The fans didn't start so I tossed it and bought a 500watt atx PS AND STILL NOTHING NOT EVEN A BEEP. I CHECKED THE SWITCH AND THE WAY I PLUGGED IT IN ,THAT IS OK. THERE ARE NO CARDS PUGGED IN SO I PULLED THE RAM, PS WONT START. I PULLED THE CPU, PS STILL WON'T START I CHECKED THE POWER INPUT CONNECTOR AND THE 12V BOARD CONNECTOR, STILL NOTHING. I PULLED MY PS AND PUT IT IN AND IT WOULDN'T START.
I CHANGED THE MAINBOARD TO A NEW PC CHIPS TIDALWAVE WITH A T12 INTELL 865PE CHIPSET. QUESS WHAT??? YOUR RIGHT STILL NOTHING.
I THINK EITHER THE MAINBOARD IS SHORTED TO THE CASE OR THE CASE HAS A DEAD SHORT IN IT. PROBLEM IS I DON'T KNOW HOW TO CHECK FOR IT DOES ANYONE KNOW HOW TO CHECK THIS OR ANY OTHER SUGGESTIONS. I DON'T THINK I NEED CARDS PLUGGED IN FOR THE POWER SUPPLY TO START.
