I got a new power supply unit and graphics card for my computer. The psu seems to work fine when I don’t have the new graphics card installed but once I install the card, my computer won’t boot. It just keeps going “beep…beep…beep…beep…” and no picture on the monitor. I turned everything off and reinstalled it twice but that didn’t work. My card is quite powerful, it’s a Radeon VGA Diamond HD4870 and the PSU is a COMPUCASE|HP585D 580W. Ideally I know the PSU should be stronger wattage but I would think it should be enough to get the graphics card to work or at least get the computer to boot up. Help…please…
My specs are as follows:
AMD Athlon II X2 Dual-Core Processor 250u (1.6GHz, 2MB total cache)
4GB DDR2 dual-channel (2 × 2GB) memory (upgradeable to 8GB)
750GB 7200rpm SATA Hard Drive
16x DVD±R/RW SuperMulti drive
Integrated NVIDIA GeForce 6150 SE graphics
8-channel (7.1) high-definition audio
10/100 Fast Ethernet LAN (RJ-45 port)
Windows 7 Home Premium 64-bit operating system
Dimensions: 14.2” H x 7.1” W x 16.2” D
Glad it worked out for you.
