I have an old HTPC. The motherboard is a Gigabyte Ga-33H-S2H. It has been rock solid for years but over the last few months I've had problems getting it to wake from sleep. Most of the time if I hold the power button in, I can get it to reboot and be ok. Sometimes that doesn't even work. That makes me think there maybe going on than just issues waking from sleep but was not sure what to try next. I replaced the video card and the problem still happens. The power supply is a 350 Seasonic but is also very old at this point. Any ideas would be appreciated. Thanks
(I should add that sometimes it can goes days waking with no problems and then will stop waking up. Then the next day it will wake normally again)
