Hello everybody, I have been building a "recycled" PC for a friend who wants to play some undemanding games (specifically, Skyrim), and after having everything ready, I find that the system doesn't go beyond the first screen of the POST when it uses an external PCIe graphic. With the integrated graphic there is, in principle, no problem (except that it is useless, of course). I have tried with the graphics card selected for the build, an XFX R7 260x, with another 260x from MSI and with a Gigabyte R5 230. The same problem occurs with all of them: the signal reaches the screen, starts to load, but gets stuck in the Intel logo and does not pass from there, without being possible to do anything (doesn't respond even to enter the BIOS configuration). I have updated the MB to the latest BIOS available on the Intel website (from 2009) and the problem persists. Touching in the BIOS options did nothing, despite having tried everything or almost everything. I've also tried booting with a single DIMM, disconnected the rest of devices, and still nothing ... Can you think of any advice? I'm very frustrated The complete specifications are: MB: Intel DG33BU CPU: C2Q Q9550 (tested with a Q6600 and neither) GPU: XFX R7 260x (tested with MSI R7 260x and Gigabyte R5 230) RAM: 4x2GB DDR2 Crucial (tested with a single DIMM) HDD: Seagate 320GB SATA PSU: Tacens Anima APII 500W SO: None, I have not been able to install it yet (and I understand that it does not make sense to install it with the integrated graphics, because then the problem will come back, since it happens outside the OS) Thank you in advance.
