Hi all,

I have an HP Pavilion p6-2055a Desktop PC with Windows 7 Home Premium and Windows 8.1 update in dual-boot configuration on separate partitions on the hdd.

The BIOS is a standard HP System BIOS and Setup Utility (System BIOS CAR_713.ROM v7.13 American Megatrends) a BIOS/UEFI hybrid.

I have replaced the power unit with an eXtreme power DF550 (550 watt) power unit.

I want to install a GIGABYTE GEForce GT740 2048MB DDR3 (model name GV_N740D3_2GI)
[NVIDIA GT 740/REV 1.0, PCI-E 3.0/2GB DDR3/128 bit. Bual-Link DVI-D x 2/D-SUB/HDMI]
graphics card.

The card should be compatible with my machine and system (Intel i7 2600 CPU/8GB RAM/1TB HDD. I have installed the drivers and utilities supplied by the install CD and gone through all updates offered in both Win7 and Win 8.1.

On machine startup, the HP BIOS (described above) presents a first screen which presents the option to press the Escape key to bring up the Setup Utility or, after a 20 second countdown, to go straight to the Boot Menu

Problem: after replacing the old card with the new card and pressing the power button, that first BIOS screen appears but I cannot get past it. With the new card installed no input devices are recognised - i.e. keyboards and mice, wired or wireless and so the escape key cannot be recognised nor any function keys, and, after the 20 second countdown, the machine effectively goes to standby power mode instead of going to the Boot Menu.

Nothing I have tried in any configuration can get past this. I have even setup the machine configuration to skip the BIOS screens altogether and go straight to the Boot Menu after power-on, which works with my old card, but the new card ignores this somehow and the HP BIOS screen appears.

Has anyone else encountered this or a similar problem? Does anyone have a solution? Any help will be greatly appreciated.

You need to go into the bios and disable UEFI by switching to legacy mode.

If you cant get into the bios with the new card, put the old one back in to do so.


Did you uninstall the old drivers first before the new drivers?

Also the CD drivers that come with the gpu's are whoefully out of date.

I suggest putting the old gpu back in, using DDU to remove all gpu drivers, downloading the proper drivers for the new card to the desktop so you can find it.

Turn off the computer, install the new card. Then go into windows and install the drivers.

Hi Maxiage, thank you for your reply.

Unfortunately, no luck. To answer your points in order:
BIOS (not UEFI) I had reset to defaults already. Lecacy settings in all cases.

I always uninstall old video drivers first before updating them, so, yes.

Problem persists unchanged as described.

With a bit of Googling around, I have found reviews that state GIGABYTE cards are frequently temperamental and that original machine BIOS and the GIGABYTE cards onboard BIOS (?) óften conflict. Whether this is true and what it means in practice, I cannot say as no-one I read managed to be clear about it.

Still looking for a solution. Thanks again though for your reply.
