I'm getting a blank screen after installing my video card.My computer appears to be booting properly,and I know my monitor works. I have a Geforce 3 ti 200 packaged as a Gainward Ti 450 Golden Sample. I was having problems with this card and had sent it back to Gainward for warranty, and they sent me another card. Installation process went as follows. I set my display to standard VGA, uninstalled my old drivers, shut down computer, removed old card, inserted new card into agp slot, plugged in monitor,mouse and keyboard booted computer and nothing but a black screen. As I said the pc seems to be booting fine. (no abnormal beeps) Any Ideas??

Have you tried booting into Safe mode?
Do you have video in safe mode?

*Slaps Gecko with a big trout* He said he cant see ANYTHING. How would he get to video if he cant see anything. You have to START the computer first and press F8 at the appropriate time to get the start-up selections. If he cant see anything, how do you expect he will get into SafeMode? :lol:

You're a funny guy Gecko! Did u install the drivers for the video card before uninstalling the old ones? Did you set the computer to load the drivers for the video card instead of the old ones? (If not, the computer will try to locate the old files,(which arent there cuz u deleted them) and your video card wont work, resulting in no visuals)

All I can really add is to reaffirm that if you are not even seeing any BIOS messages, it HAS to be either a duff card/cable/monitor/AGPSlot. Since the computer seems to be booting, I suspect the AGP slot is probably fine which leaves the card, cord or monitor

The monitor and cord I know are fine because I'm posting these messages with the same pc and monitor in which I'm having the problem installing the card, and the card that I have in now is plugged into the agp slot.

I would say that this sounds just like before, if you are not even seeing any BIOS messages, it has to be either a bad card/cable/monitor/AGPSlot.

If you really want to know how much wattage is needed for your system then take the voltage and the amperage used by a device and multiply together to get the wattage requirements.

The below table and formula is from PC World online and shows
the average wattage needed for the component listed

AGP Video Card 30 – 50W
Average PCI Card 5 – 10W
10/100 NIC 4W
Floppy Drive 5W
CD-ROM 10 – 25W
CD-RW 10 – 25W
7200rpm IDE Hard Drive 5 – 20W
Case/CPU Fans 3W (ea.)
Motherboard (w/o CPU or RAM) 25 – 40W
RAM per 128MB 8W
Pentium III Processor 38W

For overall power supply wattage, add the requirement for each device in your system, then multiply by 1.8.
The multiplier takes into account that today’s systems draw disproportionally on the +12V output.
Furthermore, power supplies are more efficient and reliable when loaded to 30% - 70% of maximum capacity.
