K7T Pro2-A no video, please help

[BoogieNights]

Hi,

This motherboard is the third already! I have returned
my 694D Pro-AR, CUSL2-C, p3@933, coz I thought they're
trashed!

But still.. I got no VIDEO!!

VIDEO card, DIMM... were tested fine!

Do you think it's my Antec SX830 300W power supply???

Thanks for any input you may have!

Stupid question, but are you sure the monitor is good?

You have changed the board more then once tried both Intel & AMD boards also had the video & ram tested ,so that leaves the monitor & PSU, btw are you getting any power at all from your board like fans etc?

 

[BoogieNights]

Monitor is OK... I'm actually using it now.
Fan is running.... everything.

But, this is my third mobo and a new chip.
K7T Pro2-A+TB900

My 694D Pro-AR, CUSL2-C - same problem.

Here's what I did.
1. Put the RAM (tested on other board)
2. Put the CPU+fan
3. Put video card (tested on other board)
4. connected everything + monitor/cables/switches

FD/HD doesn't matter right?
I should get a POST right?

I would have the PSU tested or try a different one,it seems most of your parts have been tested or replaced so start checking the parts that have not like PSU.

 

[SinMen]

Kind of off topic, but anyone has suggestions how to test a PSU?

stick it in a working system with no problems and then do some heaving game and reboot a bunch of times. If you yet a bunch of random crashes/errors, then you have a bad PS most likely

I had this problem with my new kt7pro2a and tbird1000. All of the diagnostic lights were red and I didn't get a post beep.

On a lark, I discharged cmos, and was then able to boot. Unfortunately, every time I power down I have to do discharge with the jumper again to get it to boot again. I'm getting tired of resetting my bios prefs, but at least it works until I get a replacement or get the problem fixed. I've tried reflashing, but it didn't help.

Now I've seen in some older posts that this in not uncommon, so I suppose you've read about trying the reset button after the cold boot. Weird.

I had a similar problem when I first built my system. Turned out I was a bit too generous with the thermal grease for the CPU heatsink, so the processor would "short" and the MB would stop the boot before damage occurred. I'd check your processor/heatsink for a good setting and no excess thermal compound.... if you already haven't done that.
