Hi all. New poster with weird problem.
Set up:
AMD K7, 256Mb memory, AMI bios
Video from NVidia GEforce FX5200 2048kb, AGP
Running WinXP Pro
Recently replaced my PSU when the old one gave ceased working.
OK, confession time. The old one gave up when I was trying to connect up an extra hard drive, so I fear that I may have fried something through static.
Anyway, new PSU is XPower ATX-400TD. The old one that it replaced was the 300W model that came with the case.
When I now press power button to switch on, fans come on, lights for CD flash and all sounds as per usual. Except that the monitor doesn't always come out of sleep.
If I hold down the power button to switch off and then try again, the monitor will then wake up and all is fine.
But if I then reboot again, back to square one - fans, lights but a sleeping monitor!
I've taken the new PSU back in case it was faulty - got an identical replacement and got identical problems.
Ideas anyone? Here are my thoughts to date:
1. PSU faulty? Unlikely as I've just swapped it out again.
2. PSU not up to the job? Also unlikely as my old 300W unit has been replaced with a 400W unit.
3. Poor Power_OK signal from PSU? If this is the case, why does it work on the second boot but not the third?
4. Damaged motherboard or video card? Possible, but why this regular works/doesn't work pattern?
All ideas welcomed, before I start replacing kit at random!
