HP p6755a Desktop i5 310;
I was attempting to change my stock standard video card to a ASUS GTX 750 card. The new card did not work. After powering down I put the old card back, and it also does not work. No HDMI, DVI, or VGA
I pluged the screen into the onboard DVIe Port, and still can only get the HP Welcome Screen, it says Push Esc to the Startup Menu.
It Just sits there like a sack of potatoes with all fans running.
I cannot start the computer to Windows7 and I cannot get to the Bios Setup (Esc Button, F1- F12 ).
The computer opens on the HP Welcome Screen and says Push Esc for setup. If I hold the Esc button then start the machine, it goes to a screen with the machine parameters or spec? It also says Push Esc for Startup menu.
I have tried to start to a Memory Stick with MS-DOS, Windows7 Disk, and a Windows Emergency Startup Disk, all to no avail. It does not want to proceed past the Welcome Screen.
Please Help, I have run out of ideas.
