Windows 7: MSI 7528 MOBO and bad on-board VGA port

MSI 7528 MOBO and bad on-board VGA port

Hello all-I am having a host of problems with this. Hope someone can help.

I have a W7 Pro 32k desktop PC with an MSI MS-7528 mobo.
The on-board graphics port is for sure bad; the output on the monitor is fuzzy and has horizontal lines throughout the screen. But that's not the problem....

The mobo has (2) PCI 1.0 slots; (1) PCIe x16 slot; and (1) PCIe x1 slot.
When I try to install a replacement graphics card and then connect a monitor to the new graphics card's VGA port, I get a "check video signal" error message on the monitor.

I have tried (2) different graphics cards.
#1 is an ATI Rage PCI card, which has been installed in both of the available regular PCI slots
#2 is an MSI RX9250 ATI Radeon graphics card, which has been installed in the PCIe x 16 slot

No matter what, I am never able to get a signal to the monitor. That is also after pre-installing the drivers for both cards and disabling the on-board graphics adapter and several power cycles.

Is this just a bad MOBO? Or am I installing the wrong types of replacement graphics cards in the wrong slots?

Any help would be greatly appreciated....

Have you tried different cables and a different monitor with any of the other cards?

Given that you've tried PCI, PCIe and onboard, I'd be suspecting the mobo, but trying a different cable and monitor will prove it. At that point you will have isolated everything.

Every search I do for your mobo gives me a G31 board, which, with all due respect, is one of the worst board on the market (IMHO). I installed a few for customers who requested them, but they always had problems within the first 12 months.

Hi Tanya,
Yes, I tried (2) different monitors with (2) different monitor/VGA cables, each getting the distorted screen output. Those monitors, btw, work fine when connected to other PCs.

As far as the quality of the MOBO, I only repair and rebuild them at work; this is what I was given to work with, so I can only try to make it work to the best of my abilities. I didn't know if there was something I am missing as far as diagnosing the issue. It sounds like it is indeed just a bad MOBO. The shame of it is that it's only 2 years old and I have been able to squeeze at least 5 years out of PCs in an industrial manufacturing plant.

Thanks for the help!
