Hy all!
Well, you all know Alice; my IBM 5150 PC system. Well recently, the computer has begun having this little issue when I use certain programs. One of them is Microsoft Works, and another is XTree Gold. When typing while using these programs, the video image seems to kind of "flicker" like the keyboard is introducing some kind of noise. This happens whether or not I'm using the expansion unit, and not on every program, but primarily programs that use color. In Xtree, it occurs when I press the arrow keys to navigate between menus or programs. In Works, it happens whenever using any of the data entry programs including word processor and spreadsheet.
My 5150 is a 3rd gen system, with 256Kb of RAM on the mother board. Of course, I'll provide whatever other information you need to help in troubleshooting if I can. I would include it here, but I honestly don't know where to begin, other than what I see on minuszerodegrees.net. I've had the system open many times, and haven't seen anything "visibly" wrong, so burnt areas, no missing cap bodies etc. Could it have anything to do with a faulty capacitor in the power supply, or another of the power supply components?
Since I'm essentially still new to troubleshooting with these computers, I was wondering too, if it may be due to some kind of line interference, or possibly a series of blown tantalum capacitors that I haven't seen?
Where do I need to begin looking? What could cause this. What would be a worst case scenario?
Thanks in advance.
