I have this system, all stock standard from Dell:
Dell XPS 8300 i7-2600 @ 3.40GHz
8GB RAM, Windows 7 Home Premium 64-bit
Video card: Radeon 6450
460W PSU
I just bought a HIS Radeon 7850 2GB video card which from all the research I did should work fine with this PSU despite only having 460W vs 500W recommended. Certainly it should at least start. However I cannot get the computer to boot after installing the card - or if it is, there is nothing on the monitor to tell me. When booting the system fan and also the fan on the video card spin, but no splash screen, I can't get BIOS to come up, and so no Windows either.
I have since read that the Dell XPS 8300 had some compatability issues with some other high end Nvidea cards, but I can't find if anyone has either:
a) Successfully got the Radeon 7850 to work
b) Confirmed that this is impossible
I have tried the DVI, HDMI and mini-dp outs, and none make a difference. I've also tried using the VGA port which comes from the mobo NOT the card. This VGA port works fine if I use the Radeon 6450 or if I use no card at all, but if I plug in the Radeon 7850 it won't POST. I was hoping I could use the integrated graphics to use the VGA port so I could then get into Windows and load the drivers for the card. I am unable to either install the drivers prior to installing the card, or else use the VGA method above.
I uninstalled the drivers for the old card, told Windows to not auto-update drivers and restarted, but the system keeps re-installing anyway. Could this have something to do with it? I'm able to stop it installing the old Radeon driver by restarting with no card, installing the Intel integrated driver, then disabling it (not uninstalling it). By disabling it, it doesn't try to reinstall when restarting. But this still doesn't get me a solution.
It seems the most likely source of the problem is that either:
a) the card doesn't connect properly in the PCI-E slot on this particular mobo, though it seems to click in nice and solidly.
b)the card is unrecognized by the BIOS (this goes well beyond my expertise so I don't really know what I'm talking about here)
c) the card is a dud and a replacement should work
d) the PSU is insufficient. I really doubt this is the case from all I've read. If this were the case I should at least be able to get to the BIOS screen - I get nothing.
e) The driver is not being installed / uninstalled correctly.
Oh, and yeah I did plug in the 6-plug power in the back of the card too. Since the 6450 didn't require a separate power supply, I've not used this cable before and have nothing else to test it on, so there's a possibility there is something wrong with it. But again, the fan did run, though perhaps that can be powered by the power from the PCI-e socket?
Before returning it to Newegg, I would like to know if there is anything I can do or if its a lost cause and I should swap for something else? And I know, I should have built it from scratch rather than buy a Dell, but that ship has sailed.
Thanks for you help!!!
