Need some video card help

Building a new computer, got everything installed but the monitor just acts like its on standby when I boot the computer.

Ok now I am really f'n confused. Took everything apart and put it back together. Monitor still won't turn on when I boot the computer, everything else turns on. I tried my spare monitor and that won't turn on. Is it possible I just have a broken video card?
 
Quite possible. Do you have any spare pci cards? I always keep one around for just such issues.

You could also have a faulty PCIe slot, but I doubt you have a "known working" PCIe card to test in it. I'd RMA the card first...that's the more likely culprit.

Also, try both outputs on the video card. If one output works and one doesn't, it is definitely the video card.
 
is the card seated correctly? if it requires extra power, is that hooked up and seated correctly? is your internal PC speaker hooked up correctly? if so, are you getting any beeps? what video card are you using? in fact, what are the systems specs?

there are a ton of things to consider before you RMA
 
I'm using a
MSI 975X Platinum Socket T (LGA 775) Intel 975X ATX Intel Motherboard, OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply,
Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM SATA 3.0Gb/s Hard Drive, pqi TURBO 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 667 (PC2 5400) Dual Channel Kit Desktop Memory Model PQI25400-2GDB and
Intel Core 2 Duo E6600 Conroe 2.4GHz LGA 775 Processor Model BX80557E6600 - Retail

My video card is a 7900GTO. The power supply has a cable that run from the supply to the pce-1 slot and I plugged it into the video card for the extra power.

I believe the speakers on the mobo did not need to be set up, I've heard a short beep on startup.

I'm really really confused.

The video card in installed in the PCI-E 8x/16x slot, I have the extra power cord plugged in and it is pushed into the slot pretty good. I tried to put the card into another slot and nothing came up on the monitor.
 
Yeah. RMA your card. You definitely have enough power for your card. If you get a new card and it still doesn't work then its your mobo.
 
I've had this problem before, many times. And each of thoes times, it was a bad motherboard. Before you RMA your card, I recommend putting a known-working video card on your motherbaord and see if you get any video. If you don't, replace the motherboard.

My old computer is well, so old that it has a agp card and I don't believe the new mobo has a agp slot so I'm out of luck.
 
you get absolutely nothing on the monitor? No bios text, nada?
If so, take everything out (including hard drives), leave one stick of ram, then try again.

If you don't have another Pci-e vid card to put in there, take the Pci-e card out and take it to another computer with pci-e slot, and try it out. I'm betting power supply here, by the way. Can you check the power supply on another computer/use another power supply in this computer?

You'd be shocked at how many psu's are DOA.
 
I got my hands on another pce-i video card, took everything out of the computer except for the powersupply, mobo, video card, and ram. Plugged it in - powersupply light up and fan started to spin on the video card, the heatsink fan and the case fans were spinning. Still nothing on the monitor. Nothing, it just sits there with the idle light blinking - it's not the monitor because I tried the one i'm using for my backup computer.

I am so confused at this point and pissed off.
 
get another power supply if you have one handy and try it out.
I struggled for two days once with power supply issues with sympoms you describe. I put two different NEW antec supplies into my system, and got the same results. Tried it with an old 350W psu, and voila.

Just something to try before you start RMA'ing things that may not be bad.
 
Alright, I put in a old powersupply and just hooked up with video card, and motherboard. Started it up, video card fan goes on - Nothing on the monitor once again - WTF is going on?
 
no offence, but I gotta ask. You do have the 4 pin aux power connector plugged in, right?
If so, then looks like a bad mobo. Might check to make sure it's not grounding out anywhere, and also check cmos jumper to make sure it's not in the "clear" position.

Is this your first LGA775 mobo build?
 
No offense taken, I'm a new to this type of stuff. The 4 pin aux connector just plugs in next to the 20 pin one correct?
 
yes. that's the one I'm talking about.
Also, if you're really *new* to this, then I have to ask if you remembered to install the standoffs on the mobo tray before you attached the mobo. More than a few (myself included) have forgotten to do this at some point..
 
The standoffs are the pins screwed to the case correct to support the mobo right? If so, I put a standoff for each hole in the mobo. I'm a little confused about the cmos jumper.
 
in general, you shouldn't put a standoff in each hole, only those that line up with holes in your particular mobo. A good practice is to count the number of standoffs you install, then make sure you have that many mounting screws installed after you're done.

Could be that you have an extra standoff that is shorting out your mobo.

The CMOS jumper should be called out in the mobo manual. If you haven't done anything with it, then it's probably not the problem. It's normally a three pin deal with two of the pins shorted with a two pin jumper. you move the jumper position to clear the cmos, but you have to move it back after or it will cause problems.
 
I have a standoff for each hole for the motherboard so I have 8 standoffs. Is that too many?
 
I took off all standoffs, took the motherboard outside the case plugged the video card in and turned it on. No beeps - monitor still does not turn on.
 
Yousay you had 8 standoffs installed. Did you take out 8 screws? If so, then:

well, sounds like it's narrowed down to these three:

Bad Mobo
Bad CPU/ cpu installed incorrectly
Bad Ram

Have you checked to make sure you have no lga775 pins bent? This can happen.
Can you try any different ram?
 
The 4 pin aux connector just plugs in next to the 20 pin one correct?

Not quite.



From the picture of the motherboard (stolen from newegg), there is a 24Pin ATX connector, there is a 4 pin CPU connector, and a auxiliary (molex type) 4 pin connector. All of these should be plugged in.
