Hi I have a PC that was pretty decent when I bought it about 8 years ago:
Motherboard: Gigabyte GA-MA790GP-UD4H
Processor: AMD Athlon x2 250, 3000 mhz
anyway, the PC is old so things have been crapping out over the past few years. The graphics card died about a year ago and since I don't really use the PC for anything that requires intensive graphics, I just started using on-board graphics to plug in the monitor via VGA. Not too long ago I bought a second monitor (BenQ GW2470) and and am using it in tandem with the older monitor but through HDMI. This is the only major hardware change to the setup and at the time it seemed to cause suspension problems in Windows (it wouldn't wake up), which I've been working around using hibernation and not allowing the computer to enter into suspension (so it's working more). For about 6 months this seems to have worked fine.
However, recently when I boot up I think it's the PSU that emits a high pitched whining and the computer has trouble posting. Often it won't post at all, unless I unplug every peripheral, monitors, printer, webcam, speakers, etc. Once it hear the post beep I can plug everything in and it will work and, over time, the whining decreases and disappears as the computer seems to warm up.
I'm assuming this is a PSU issue, but I also wonder if the motherboard could be struggling with the new monitor?
I'm thinking about buying a new PSU, does that seem like the right solution to this problem?
Any advice is greatly appreciated.
