I have waited for a while to be certain.
The problem has gone away. And I do not know why.
I reassembled everything and it all works.
- was it the PSU and when I got the new one and did my first tests I did something wrong?
- was it a short to the case that somehow resolved itself when I...
I followed Iron's advice above
Bench testing - out of case tests
- nothing connected except power and internal jumpers. No video etc.
1 small beep, pause, 1 loud beep
- as above + VGA video.
similar beeps (cannot be certain, did not note), screen message saying 'no KB'
Bios on screen ...
I was wondering if my PC speaker was not working.
I took out the 8GB memory card, and got repeated beeps, 1 long then 2 short.
Just what one would expect for ASUS BIOS beep codes.
I put back the memory, try again, silence.
I will try the 2 above posts later today.
The PC only has 1 8MB memory stick and this is the one I tested earlier. No USBs, drives, cards connected.
I tried again without the mouse, no change.
I even tried without the KB. Still dead.
As for checking under the MB, I need more light. I'll try in the morning.
Yes (update) and no (progress).
I have the new Corsair PSU and it is plugged in but the PC remains 100% dead.
All internal devices are detached (drives, cards etc) but jumpers etc are still in place.
I apply the power, use the PC power switch, the PSU and CPU fans turn, and then nothing. No...
I tried with an old PSU that I had, but the P4 connector (the one with just 4 pins in a square) is different.
So I have ordered a 550 watt Corsair from Amazon.
With Xmas coming, it will not be the usual quick delivery.
Thanks Both
I agree, time to assume the PSU is the problem. When I did the upgrade in August I used the old PSU and it is a cheap, no name probably Chinese one, but reasonable wattage but it has no sticker so I cannot say.
I post again when it's done - the PSU swap.
Currently my PC is dead. Do I have a PSU or MB problem (or something else?)
The problem was progressive over about 5 days.
- at the beginning, it would crash (either black screen / frozen screen / screen tearing) after a short time, say 10 seconds to 2 minutes. A reboot might or might not fix...
