So I have purchased a new gpu for my HP pavilion, http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c03397907
but after installing it my computer would not boot. After a lot of troubleshooting I have found that my computer only boots when the monitor is plugged in. The GPU is a gigabyte gtx 660 OC.
I have replaced the PSU in my computer for a corsair 600W one, and have correctly seated the gpu and plugged in the neccresary power connectors. The computer works fine with my old gpu, or no gpu, and I have already replaced the gpu so it is not faulty.
So here is exactly what happens. If I turn on my computer with the monitor plugged into the 660, the computer will freeze at the HP startup screen where it says "press esc for startup menu". Pressing esc or any key does nothing. Eventually it will switch over to a black screen with a flashing underscore in the top left. It stays there and doesn't change.
If I turn on the computer with the monitor unplugged it does something different. When I turn it on the power button on the pc flashes orange and beeps 6 times, and the computer then begins to start up. After about 2-3 minutes I hear the fans slow down so I know the computer has started, I plug in the monitor and everything runs perfect. If I plug in the monitor half way through it is just a blank screen.
Really need some help, I have no idea what to do.
Thanks.
