No Input Signal

Hi,

I have been having a recent problem with my computer. I have a Abit vt7 mobo with a Pentium 4 3.02 ghz processor. 1 stick of DDR Ram 512mb. 80 gb SATA HDD, and 160GB serial IDE HDD, DVD Burner, Cd Burner, Floppy etc. I am running a Antec True Power 450 Watt Power supply.

The original vid card I had in there was a Geforce MX330 gard(I think) nothing fancy. I had recently upgraded to a Geforce 6600(Gigabyte Brand---has a Pipe Cooler instead of a Fan).

When I was using the old vid card I was having intermittent problems with the PC not getting vid signal. My PC is on 24/7 pretty much so I would only experience it when I would turn off the computer for a few hours. Usually a Cold boot would remedy the problem. I thought the issues was with the original ps I had which was an offbrand 300 watt powersupply. So I got the Antec 450 and also upgraded my vid card.

Things were working fine again, I then had to do a shutdown(problem does not happen on a restart) and when I went to power back on I'm getting no signal.\

I have swapped vid cards, reseated the processor, checked RAM, Checked all connections and still can get not a thing from any vid card.

Does anyone have any idea what could be causing this. I also double checked to make sure the board was not shorting and it is not.

Heck I even got a new monitor cause I thought my monitor went bad, but still no go.

A very frustrating situation hoping someone here could possibly shed some light before I pull my hair out. I had to post this message on my fiance's pc.

Thanks!
Alan

 

Sorry should have listed.

Its an AGP card both the new one and the original one that was in there. I have also tried to clear the CMOS as well but no luck. The computer does POST normally...just no signal.

 

I was thinking that could be the problem. The Mobo I have doesnt have any onboard video though.

I guess I will have to pick up a cheap PCI Vid card and see if that fixes the problem..

It's just frustrating...

 

I could double check, but would I even be able to do anything. I cant even get into the BIOS since I can get no signal from my vid card.

 

It had in the past, but not now...I just power up and the monitor just displays no input signal...
