I just bought an EVGA GTX 750ti to upgrade the GT640 I have on my Acer3985 (with i7 3770, 2x4Gb RAM, 300W PSU).
I made sure to buy a model that was in the range of my PSU and took the EVGA 02G-P4-3751-KR. No 6pin required and 300W minimum.
The first surprise was to read on the box that it needed 400W and 20Amp on the 12V+ rail but I tried it anyway (I sent an email to EVGA to know what are the actual minimum requirements).
The computer didn't boot and got stuck on BIOS. I got 3 bips every 30sec or so (after the first normal bip), could see the ACER splash screen but after that, black screen with the white "_" cursor.
I saw here and there that it could be fixed by disabling "Security BIOS" or by enabling "Launch CSM" but neither of those options are available on my BIOS.
I then tried to remove the "quiet boot" to check what was going on and even though I got the same 3 bips every 30secs, the computer started afterward. I was able to test the card, install the drivers and everything was fine except for the strange boot with BIOS stuck for more than a minute.
I realized that while the BIOS was stuck, I could only see the American Megatrends logo but nothing else, no text. I tried going into the BIOS with that setup and landed on a black screen.
So I think the boot delay might be due to the BIOS having another display than the card as default and trying to use it in loop, then when the OS starts the card works. Of course, no option in my BIOS to change the default display output...
I still don't understand why the "quiet boot" makes the OS boot possible when disabled.
So I'm left with 2 possibilities :
- the PSU is insufficient (I did a quick Furmark test and everything was fine at 100% load though)
- the BIOS is missing options to avoid the strange boot but I could use the card if I can deal with it at each startup (and no access to the BIOS).
What do you think ? Do you see another option or solution ?
PS : there is a newer BIOS version but it won't change the options in it according to other posts (nothing newer than 2012 anyway).
PPS : this thread pretty much shows someone else having the exact same problem but with others PC/GPU. But the BIOS options are pretty much the same as mine : http://steamcommunity.com/discussions/forum/11/558749824211499896/
Thanks in advance !
