Hi, all. New to the forum, jumping right in with a perplexing issue. New to this, so hopefully have provided info as detailed as possible.
We have a Gateway GT5228 AMD Athlon 64x2 4200 PC that needed repair. It's about 6 years old.
The issue started when my screen went wonky with lines all over the place and a frozen system. Restart resulted in the pc just not booting. After searching, found the problem may have been the gfx card or power supply, yes? With an onboard gfx card, we assumed we needed a new motherboard, so that's where we started and replaced the old with a new FIC K2BC51LF. Everything was fine for about a week, then the computer, again, would not boot.
We tested the power supply. Sure enough, it was bad. Replaced a DP8-300PB-3A with a GT5228-550W24P. Still no boot. Fans ran, lights were lit but no signal, once turning on the monitor. We reset the bios, manually, still no go.
We purchased a diagnostic repair testing kit that pointed to the cpu not being read, so replaced that, next. Went from a GT5228 AMD Athlon 64x2 4200 to a GT5228 AMD Athlon 64x2 6000+ 1024 Socket AM2 Dual Core ADA6000IAA6CZ. The system is still not booting and the cpu is still not being read. Again, we reset the bios, manually but this is not working. We unplugged everything but the monitor, to check if it may have been caused by something else, but no luck. We are clueless as to what to try next.
The hardrive was replaced, last year. The monitor is about 3 months old. We don't have another to test on, as our old has a faulty power button. Any ideas as to what we might try, next? Is it possible our hardware is not compatible?
Thanks for any help.
