I have a machine that was built by someone and I don't know who. I believe that the motherboad is a SIS 530. Anyway, when I tried installing a new video card I got absolutely nothing. I then tried to re use the old video and still noting. Please help!

When you boot the machine, do you get a series of beeps ? Does the computer show the POST screens?
Is this an AGP or PCI card?
If it is just a black screen with no beep codes, I would be prone to blame the monitor first. Have you tried a different machine on the same monitor? If you are sure that the monitor works, check the cable connections and the card itself to make sure that everything is seated correctly.
Still no display? If this is a PCI card, try a different PCI slot (you can't do this with AGP - there is only one AGP slot).
I have seen expansion slots that were burned - hopefully that isn't your problem. The only way to fix them (realistically) is to replace the board.
Post back and let me know how you fare.

No beeps, no POST screen, nothing. Its a PCI card. Tried the monitor on different system and it works fine. Tried the system on a different monitor, nothing. There is a NIC card in one of the PCI slots and I tried the card in that slot and it still doesn't work so it can't be my slots. Also, tried the card in a different system and the card worked there.

when you power up does the fan in the power supply spin up? anything at all from the powersupply? if not, do you have access to a different ps to try?
i had a problem board one time that kept the powersupply from coming on.
make sure the power connections ( and all other connections) didn't come loose while you were working in the pc. even check the wires at the power switch to rule that out.
an atx board will have the main power connection and also the power button connection from the case to the board.
did you check the voltage setting switch on the back of the power supply? was it accidently set to the wrong voltage?
try reseating the cpu and memory
if you still get nothing, try removing all cards. disconnect harddrive, cd drive and floppy drive.leave the cpu in and keep the speaker connected. power up.
if you get signs of life add things back one at a time till the problem repeats itself.then you'll know what the problem piece is.
is it possible a screw could have fallen in there somewhere and is shorting the board? could a screw have gotten under the board?
as a last resort if you haven't tossed the computer out the window you could set the board up outside of the case with just the power connections, cpu, memory and the speaker and try the power one more time.
can't think of anything else
hope you get your board going again
