Help, Call the Cavalry!

I've got trouble!

I've removed my old power supply to try to upgrade my Gateway tower to a 400w PS. It didn't fit, so no connections were made.

I've reinstalled the old supply, made the connections and now...the monitors don't work. Everything seems to be getting power, but the screens remain black at bootup.

My video card is an ATI Radeon 9800. I have hooked power to the card, even swapping connectors.

Any suggestions? Thanks!

Do you hear any beeps while booting?

Yes. It sounds as if its running the boot cycle normally. Can't be sure, though.

One thing I have found is first, don't panic. :)

Second, undo all of the power supply connections and redo them. Sometimes it just takes a second try.

I've removed all connectors (3) to the MOBO and replaced them. Also, removed the video card power and replaced it.

Still no monitors.

You should hear one beep during the boot cycle; if you hear multiple beeps, it probably means something is not seated properly. I would apply power to only the boot drive and video card; make sure ram is properly seated. If this configuration boots, then add other devices.

And like DaveT2 said - step back, take a coffee break, come back fresh.

I hate to ask this, but are the monitors turned on and connected to the video cards (please don't shoot me) :(

do you see the bios screen ast startup or is that black too? In other words... does it just stay black as Windows is loading? (ATI drivers are the worst known to man IMHO)

In addition -

if the mobo has onboard video did you go into bios and make sure it was disconected. (Ok - I know without any image on the screen you can not really do this so if there is onboard video did you plug your monitor into that?)

And did you swap out your graphics card with another one to make sure it isn't the graphics card?

Did you take out and reseat the graphics card? Also does the card require any power and if so did you plug power into it?

Yes. The the monitor are on.

Re-seat the graphics card. Get a magnifying glass and flashlight and check the pins on the video card and the cable for bent condition. Did you forget to hook the power connector to the motherboard or did you put it in half way or backwards partially? Did you bump the processor out of place a tinge? Are you plugged into the correct video card jack?
Was the power off when you did all of this?

Make sure you don't have any unpolarized power connectors (they do exist!), i.e. connectors you can put in backwards.

Working on it. Everybody hang loose!

Still no monitor. Sorry for the delay...had to take care of a customer.

1. I've pull all cables and reseated, care to set polarity correctly.

2. Pull the video card, inspected and returned to slot.

3. The proc and RAM were virtually untouched, so I ain't messing with that.

4. Computer cycles normally on boot.

5. Monitors have power. It's almost like there's something not plugged in. When I plugged to the MOBO, there were 3 plugs...(a) a 24 pin (b) 4 pin (square) and (c) 5 or 6 pin molex type connector. On the video card, I plugged in standard 4 pin device power.

What could I be missing?

Do you have another video card to try ?
MichaelS wrote on 3/8/2006, 10:29 AM
I tried an old video card (that works) and still nothing. Maybe it's not video card related. Have I missed a connection to the MOBO?

Did you mean the old video card works or that it does not work? if it does not work than did you try another slot? And I did not see where you checked/tried any on board video. That could be the main issue right there if that is the case.

Can you see anything on the monitors at all? In otherwords can you post and go into BIOS ?

If not perhaps you need to re-flash the bios -- maybe it lost the bios during your power experiments

Monitors are totally black. Usually they will be in a puse mode until the computer comes on. They are not leaving the pause mode. The other (working) card I tried did not work either.

Hmmmm.

Have you connected power to all of the other system components as well (i.e. Hard drives, optical drives, fans, etc.)? If one component isn't connected properly, then it'll likely prevent a computer from starting up.

I'd recheck each component to make sure their data and power cables are seated properly (at the component and at the mobo).

I think you meant to say cavalry.

Calvary was the hill near Jerusalem where Jesus was crucified.

I don't know, it sounds like he might need a "laying on of hands" to fix this. :)

Jay,

Spelling never was my forte.

Nonetheless, it looks like I'm going to have to call in a pro. I'd appreciate any other ideas in the meantime.

Thanks!

on most maybe all boards there is a jumper ,to set the system back to fail safe operation, if you have the motherboard book it will point out the jumpers. This may get ya going.
Starting to sound a little like what I went through a couple a weeks ago, a $3.25 cmos battery, I didnt know it was bad till i unplugged the computer.
