Motherboard or PSU ?
The problem begin with a crash, no BSOD, no error
messages. On trying to restart the PC would power up
momentarily, shutdown, then try to powerup again
repeating this process. This sounds like an issue with
my BIOS settings. I reset the motherboard by unplugging
the power, turning the power switch to off, moving
jumper to the reset position, removing the battery etc.
Try to start the PC. Same thing happens. Now I think it
may be my graphics card. At the time there was a radeon
HIS HD6950 in the PC. I replace the card with a nvidia
GeForce 550GTX TI. The PC starts & post.
All is fine for maybe an hour. The pc once again
crashes with no errors. This time when restarted it
powers on for maybe 4-5 seconds longer than it did with
the HD6950, but will restart, power up & stay powered
up without posting.
The only way to get it to post again is to reset the
motherboard as I did above. At this point I was leaning
more towards my power supply possibly becoming weak.
Until I started to notice the USB ports on my
motherboard would stop working not long before, or
immediately after not working again until i reset the
And I can’t update my BIOS because AsusUpdate never
works & I’m not sure how to do it with the .rom and dos
so I’m not too comfortable with it.
Thanks for any advice, need to know if my next move
should be to try swapping the PSU or swapping to a new
mobo, thanks !
