Fans and DVD kick on but that's it

[BBSCPossum]

I have a KT7A-RAID...I was trying to install Windows but it wasn't reading my HD. So I shut it down and opened up the case, the power wasn't hooked to the HD. So I plug it up and try to turn on the power. My fan's and DVD come on but that's it. No video, HD, or Floppy. So I unhooked everything except for the Floppy, Ram, Video, and Keyboard. Same thing happens. I reinstalled the video...same. I took the battery out and put it back in. Same. I am at my wits end...it doesn't make sense. Has anyone else had this problem? Can you help?

Recheck that you have the mouse and keyboard connected to the right sockets.

Remove all ram, and replace one module only...seat it down HARD...just before getting a hammer, stop. Ram modules not bottomed out in the sockets are the cause of most problems.

That wasn't it. I've tried Everything and I think I know the problem. I took my Video Card out and booted and it sounded like it kicked on right. I could turn it off and on by the front switch. I think it's because right before I shut it down I set my video to enable 4x and saved it, then turned it off. Then I opened the case and plugged the HD in. I can't get in to change my settings though. I can't get my video going. Thanks for the help.

You should be able to reset the bios to factory defaults. There is a 3 pin jumper near the battery or bios chip. This should now have a jumper on pins 1 & 2. Move the jumper to pins 2 & 3 for about 10 or 15 minutes to discharge the capacitors that power the bios during battery change. If in doubt as to exactly where this jumper is, your manual should have a pic of it. I did have a pic of a KT7A board here but must have deleted it. Replace the jumper to pins 1 & 2. Be sure the power is completely disconnected from the wall...ATX psu's have a 5 volt circuit that is on all of the time the computer is plugged into a hot AC circuit.

I know exactly what you're talking about. The CMOS jumper. I did that but didn't have it completely unplugged, I'll try it out and get back to ya. Thanks man.

[BBSCPossum]

Didn't work but thanks man, I really thought that may have done the trick. Back to the drawing board.

Awww ****, I thought surely that would do it. If I can think of anything else, I'll repost. BTW, I have read of several KT7 type boards having bios chip problems recently...maybe a defective bios chip?...they do go bad...the memory cells can fail, and it only takes one. This should give a 'checksum error' tho.

RPM from the fan?
Badly seated CPU?
Heatsink not sinking on chip right (i.e. concave base)?

Just some of the things that have stopped some of the machines starting I have worked on!

Well, I rebuilt it from the ground up. Everything seems to be working except my video card. My monitor will flick when I turn the PC off and on, but it's not bringing it up on the screen.

When you reset the BIOS, did you remember to move the jumper back to its original position? ;)

[BBSCPossum]

Yeah, it's gotta be on 1-2 or it won't even power up.
