I have trouble on my video card/motherboard that my monitor doesn't detect any signal during boot-up. Can some PC expert help me on this? I really don't know what the problem is after a series of testing.
PC components:
Intel i7-3770K
DZ77RE-75K
Intel SSD hard drive 520
PowerColor 7870 Myst PCIe 3.0
850Watt PSU (should be enough)xi
Windows 7 Professional
My motherboard comes with two PCIe x16 slots, and one of them is x8 electrical. When I first install it, I put my video card in the x8 electrical slot and it works fine except the graphic isn't that great. I soon figure out that I should use the primary slot instead of x8 electrical slot. After switch the card into the right place, the monitor doesn't detect any signal. I have tried to configure the BIOs as booting PCIe (PGE) first and disable the on-board video card (I tried a lot of setting). The card is still not showing up, so I think it might cause by failure PCIe slot. Then, I install my old PCIe 2.0 card onto the primary slot and it works. I re-boot several times to verify this primary slot is working.
Just one try, I delete the driver of my new card in hardware manager under Windows then put my new card back on. Magically it works. So I shut off my computer, put every in place and close my case..... The nightmare comes again... When I try to turn on again, the monitor now doesn't detect any signal... I login using on-board video and check the pre-install driver of my new card and it's not there. Now, I don't know what should I do? Does anyone have solution for this problem? Thank you...
