Need to replace video card

Dell Dimension 8250 desktop
April 2, 2010 at 13:09:00
Specs: Windows XP Profesional
I think I need to replace my video card on my old 8250. I have the P4 3.06 HZ, 1.5 GB RAM, and the 128MB DDR ATI Radeon 9700 Pro w/TV Out and a 1900FP monitor. I'm getting five vertical bars that flicker - it did this two years ago but stopped and now it's come back and a lot worse. Don't want to spend a lot of money; just trying to squeeze more life out of the desktop. Used mainly for surfing and work. Any suggestions would be greatly appreciated!

Power off the machine, unplug the AC cord and try reseating the video card a few times. If the contacts have corrosion that might scrape it off.

Thanks for the suggestion! I tried it; couldn't get the card out but I was able to slide one end out slightly (I was afraid of damaging it). I reseated the card and the bars are still there. I'm wondering if the fan on the card has stopped working and it's over heating. It was quite warm when I opened up the case...

Check to see if you have good airflow through the power supply. Is the fan running at a good speed? Are the power supply vents on the inside blocked with dust bunnies?

You probably should check your temperatures. On some boxes you can do that in the bios. If not, there are free programs that will do it, for example 'Speedfan'.

Thanks again. The program works great on my laptop but doesn't seem to be working on the desktop. It recognizes the the three fans but shows the RPMs as zero. I know they are running because I can hear them. The temp is showing in my task bar as either 00 or 88F; can't tell for certain due to the screen distortion. I think it says 88. It shows 118 on the laptop.

BTW - forgot to mention that the air supply thru the power supply is good. Got rid of all the dust-bunnies when I opened up the case.

I assume that you couldn't find the temperatures in the bios.
I've used GPU-Z to check the video card. You could try it.

How about running with the case open and a fan blowing in. That would probably help to determine if it's a heat problem.

Problem is; 9700 Pro doesn't have a temp sensor. Every program you try will tell you the same thing about video card temperature.

Nothing.

Yeah I couldn't find the temp in the bios. Thanks for the tip GPU-Z. I tried it and it seems to be working fine.

I'm still thinking about changing out the graphics card and seeing if that will fix the issue. Just need to know what to get...

Here's a pretty good deal for an AGP card.

Any chance it could be the monitor?

Could try a lower resolution or refresh rate just to see.

Wow, today everything is working great! Wish I knew what it was; it did this two years ago for a while and then just stopped. Now I'm wondering if it was some type of hardware conflict caused by a software upgrade?

Well this morning it's back. Weird that yesterday, everything worked perfectly and this morning, the vertical bars have returned. On the opening Dell screen upon startup, it looks perfect. Only when XP is loading do I see the bars. Now I suspect that it's software related rather than hardware. Any suggestions?
