Hello,
I recently posted on this forum after having issues with my computer not booting. Then the PSU literally blew up a day later.
Old System Specs:
Q6600
MSI P7N Diamond
Silverpower sp850w ( has good reviews – just not well known)
Corsair 8GB
HD 5870
The issue I had was: turn on pc, everything lights up but GPU fan spins at full speed – as if it was getting no power or connecting to motherboard. G-card will not boot at all.
I did however find a very strange work around.
To boot the machine I had to remove the 6 pin CPU power on the motherboard.
Turn the machine on… but no boot…
Turn it off and replace CPU power
Turn machine back on and everything works perfectly.
So, It seems that the card can never boot up from cold. If I re-started it worked fine.
I now have a new motherboard, cpu, RAM and PSU. Both motherboards work perfectly with my tester g-card.
New PC Parts,
I5 2500k
Gigabyte GA-Z68X-UD3P-B3
Corsair TX850w V2
The new one fails to boot at all, even with various different power cables removed.
I cannot RMA card as it is second-hand.
BY using my trick on the old motherboard it works perfectly, so the card actually works….. It’s just having big issues accepting power to boot.
Would flashing the g-card bios help ?
This quote is from an article about flashing the g-card bios… It seems to sum up my issue..
“the video BIOS initializes the card. As soon as it receives power from the motherboard, the BIOS activates the card and identifies itself to the motherboard BIOS.
In short, the video BIOS starts and identifies the card, and provides its initial crop of settings. “
However if I can get any advice on other things to try out then I will happily do them,
The PSU’s are not at fault as There is the same issue with a new Antec 750 PSU and my brand new Corsair TC850w (which is supposed to be one of the dogs bollox of PSU’s)
Thanks in advance for your reply,
Ivan G-S
