Hey guys, thank you for taking your time for reading this, I have posted about it before but no one could help / I got few replies, I'm going to post every little detail in hopes someone may be able to come up with a solution, Thank you again for taking your time.

I recently decided to buy a new graphics card (Asus Geforce GTX 760) for an upgrade on my old one (Nvidia Geforce GTX 620) that came standard with my computer.

once I removed the old graphics card drivers and installed the new ones I ran into a problem, my computer started up INCREDIBLY slow, it used to take about 30 seconds, now it takes about 4 minutes +. And even when it does start up, around 25% of the time it just goes onto a grey screen and does not manage to reach the desktop, and on the odd rare occasion my pc will BSOD.

Whenever I restart / turn my computer on, I press the F12 / Delete key (tried holding them/ rapidly pressing them separate of course but nothing ever happens) my keyboard lights up blue so I know it's on but it just goes past that after the 4 minutes wait, and carries on to start up as normal not entering the BIOS, it does cause a few problems whilst on the computer but not many.

I looked on google for solutions and nothing has helped me yet, I did read that my computer starts so slow because it's trying to launch from my old graphics card and I need to change it from my new one and I think that does sound right, but I can't get onto the BIOS to change it.

I have tried a PS2 keyboard and still nothing. I have repeatadley tried uninstalling my current graphics card drivers and then booting but still doesn't work.

I really do appreciate help with my problem.

My computer specs / info:

Windows 7 home premium 64-bit
intel(R) core(TM) i7-3770 CPU @3.40 GHZ (8CPUs), -3.9GHZ

If there is any more info you need I will do my best to get it for you, thank you once again for reading and trying to help. :)

Hello, I tried them things and it didn't work, what I did manage to do what take out the graphics card and then I could enter the BIOS from booting up directly from the mother board, but every time I put the graphics card back into the computer it just does the 4 minute gigabyte screen and then doesn't manage to reach the desktop, I can get onto the desktop / bios from the motherboard though (not graphics card) but when I check for drivers for my graphics card when on the pc it doesn't show any although I know they are installed when I boot on the graphics card (if that makes sense), and I don't know how to change it in the Bios to boot from Pcie. if I need my graphics card in to boot from PCIE then I cannot get onto the BIOS because it won't let me if I have my graphics card in.

I don't think the driver is the problem here. The most current Windows-supported driver for the GeForce series GPU is 332.21, and can be downloaded from here.

Does the problem happen if you were to use the 620? If not, RMA the 760. If it does, test the voltages on your PSU. If PSU voltages are within tolerance, RMA mobo.
