Hi everyone,
I need your help. My computer is a Pentium 4 CPU, 2.53GHz, 1GB of RAM.
I changed my graphics card, 2 years ago, from the original, 64 MB to 128 MB. 2 weeks ago this card refused to work anymore, which means: when the computer starts, on the screen, the card’s data appears, then the HP logo, and instead of the menu or desktop, the screen just goes black and nothing is there.
I thought it was the graphics card, so I upgraded it to 256 MB, matching the computer system. The same thing happened as last time. I thought the power supply is not enough for the card. I switched the power supply from the original 150W to 400W. It didn’t work. The two cards refuse to work, however the original seems to work fine with both power supplies.
Does anyone have any idea why this is happening? Can anyone help me?
Thank you for the help,
V

OK I would say that with a 150 watt poser supply you were lucky if ran. the question comes down to why it's not working.

When you get to the HP logo can you hit your tab key to view the data that the logo screen hides? And thus to see if it is hanging at a certain point. Do you have any dust issues where you live? Dirt and corrosion can cause issues as well. Now the card you had may have died and while your new card is just that newer did you check to make sure that your system's motherboard is able to handle the new higher end video card.

I'm not to gung ho on any of those solutions but they are a good place to start. I'll watch this thread and once I get a picture of where the probelm may lie I will poin this thread to the best experts here.

One usefull tool for a situation if you are comfortable with computers is to download Knoppix and boot using it.

Download the Disk image on a working sytem with a CD burner. Burn the image file to a CD. Then boot the system in question using this CD. It will allow you to run your computer from the CD using a version of Linux. I have used it many times when I cannot get a windows system to boot. It will allow you to view your hard drive and if you have a Fat32 formatted external HD it will even allow you to recover data from a system that will not boot otherwise. Best of all if it boots and you can see your screen then you know your video card works and the problem lies elsewhere. Even if it doesn't where it stops booting will give us more details as to where the issue is as the boot process is very detailed with each step displaying on the screen.
