Problem with video

[Ukazi2021]

I've been having issues with this unit for a while. Its a desktop built with the following:"

MOBO: Asus P5K-VM
PROC: Intel Q6600 Quad Core
MEM: 2gb PNY (2x 1gb sticks)
PSU: Rosewill 550w
VCard: EVGA 8800GTS 640mb
CASE: Thermaltake Armor, the one with the 250mm Side Fan
HDD: WesternDigital IDE 120gb

I'm not getting any video, Ive tried with and without the vcard. Either way I get no video. Everything powers up fine but no dice with getting the screen to show anything at all. I'm not getting any beep codes, Ive even tried removing the RAM to see if it was conflicting. Ive reset the CMOS. Tried different monitors. Just can't seem to figure it out. Prior to this I've gone through 3 DOA Mobo's 2 Gigabyte and 1 Asus, I'm beginning to worry that some of the parts may not be working properly due to this. Asus phone tech support have not been helpfull at all, all they suggested was to buy a new CPU or PSU. No thanks, a replacement quad core is just a waste if it doesn't work.

I work as a novice computer tech, but regardless this has stumped me big time. Please help or give me some suggestiongs of any kind. Thanks!

I suspect your PSU. Could you swap it with another one and see if the system works?

Yeah, but the other ones I have are weaker and they don't have the 24pin connectors, however I can bring one home tonight.

If there are no beep codes and everything turns on I'd say you've got a bad videocard, anyway, before RMA'ing it try reseating everything and trying a friend's card.
If it's not the VGA, and not the PSU then the mobo is the most probable suspect.

well even the build in video card doesn't display anything, unless thats what you were saying
