I recently bought a new computer: HP Pavilion p6530f Operating system Genuine Windows 7 Home Premium 64-bit Processor Intel Core i3-540 Processor Memory 6GB Memory speed PC3-10600 DDR3 SDRAM memory (3x2048MB) Total memory slots 4 DIMM (240-pin, DDR3) (one available) Maximum memory expansion 16GB Graphics card Intel HD Graphics TV & entertainment experience N/A PCI expansion 1 PCI Express x16 (available) 3 PCI Express x1 (three available) 1 MiniCard (available) Hard drive 1 Terabyte Serial ATA hard drive And if I bought a new video card I could play all the new games with at least decent settings. I bought the, "Galaxy Gefore Gts 250 1gb, 256bit, DDr3. I installed it and the fan on the video card turns on, but I can't get a display to come up. Would that happen if my power supply wasn't big enough? Or am I installing it wrong?
