video problem

After a couple of reboots, the system would boot up ok. I could use the system surf the internet, do anything with no problem. But after I shutdown and reboot, It would act up again. After a couple of reboots the system would be fine. I hate to shut the system down because it would act up again.

When you checked your hard drive in the other system, did you use the same IDE cable or a different one? It could be possible you have a break in your IDE cable that you can't see, thus impeding flow of data to the motherboard....

I used different cables plus when I installed new motherboard, I used new cables that came with motherboard.

ok first and foremost how many post beeps do you receive at bootup? If all hardware is fine you should get 1 beep, bad video card 3 beeps. Second when did the loss of video happen all of a sudden or after updates? New pc or fixing old one? Did you update your active X drivers? If you loaded a wrong one you cant roll it back. have you unhooked the monitor video cable with the power on to receive the self test? regardless of the pc working the monitor should display menus etc.. or its toast. Did you hook the problem pc to another monitor or a friends/neighbors? Lastly you say you have on board video did you go into the bios and disable it to default to the card? This is probably the problem. Answer my questions and we will take it from there, good luck.

First I get only 1 beep on start-up. Loss of video started all of a sudden. This was my old pc, about 1 ? years old. I have 3 pc that I network together. This is one of them. I have no problem with the other ones. I tried on all the monitors that I have with this pc. Still does the same thing. The only updates I have done were just the windows xp updates. With the old motherboard, the monitor would not even come on with any monitor to get into the bios to disable the onboard video. After replacing the motherboard, the monitor comes on now, but when the welcome screen comes on then the screen will flicker a little then the welcome screen will change colors and lockup. The welcome xp screen is still on the monitor. Only distorted and off color. I hope you understand what I?m trying to explain to you. I?ve been working on computers for about three years now as a hobby. This is the first time I came across this. I guess you learn something everyday. Thanks

K7 motherboard.

AMD Socket A CPU?

If so, you need to enter BIOS setup and manually set the CPU Front Side Bus speed and multiplier for your CPU.

The following examples are for a Duron or Athlon CPU.
The settings will be different for an Athlon XP CPU.

Assumption, 200MHz FSB.

RAM, PC133 SDRAM:
FSB: 100MHz
Multiplier 14X
RAM speed FSB +PCI

RAM, PC2100 DDR:
FSB: 200MHz
Multiplier 7X
RAM speed FSB

I often need to clear the CMOS in order to get a first boot so that I can enter BIOS setup.
Unplug the AC power, and remove the CMOS backup battery for at least 1/2 hour.
Then plug the power cord back in and boot up.

Replace the CMOS battery before shutting down.

This is a new motherboard with cpu amd duron 1800+ installed. all settings are set. I can get into safe mode with no problems.

Let's see if we have this correct. You lost video on mobo and replaced it with a new mobo. Now you can boot into safe mode consistently but not into normal mode.

Symptoms suggest a driver issue. Generally, if you can run for long periods in safe mode, but not normal mode, there is a driver problem. I would first suspect video driver. While in safe mode, change video driver to standard VGA driver and reboot to normal mode. If system is then stable, that was the problem. Install latest driver for your video adapter and see it system is then stable.

Good luck

I change my video adapter to standard vga. It worked until windows xp installed the sis 640 video driver. Then I deleted the video driver under device manager and installed the updated video driver. I worked the first time and after a reboot, It acted up again. So, I tried to do a repair of xp with the xp cd. Now the computer will boot to the welcome screen and do what its been doing. I can?t get into safe mode because it didn?t finish repairing and reinstalling xp. I?m going to have to do a format and install. I?ll wait till my power supply comes in then I?ll do that.
