The computer is/was an Asus A7NA8X-X, cpu Athlon XP 3000+, 512Mb RAM, o.s. Win XP SP 1, Gigabyte AGP x8 slot nVidia 7600 series, silent pipe (no fan) using a 12v connector from the power supply unit. The Gigabyte gpu + Athlon cpu which supports a fast fps for playing FS2004 was bought in 2006 when the CPU was an Athlon XP 2600+. Gigabyte repaired it just inside warranty period. It blew its insides recently with green artefacts flickering on a black screen and, maybe, the motherboard and/or CPU at the same moment. I tried the Gigabyte cpu in another computer with an AGP 8x slot and it is definitedly bad. But with a known good PCI cpu, the mb could not bring up the BIOS nor beep. The mb powered up normally. No beep is beep code for . . . I'm way over my payscale here so I am writing to ask PCBuild subscribers for help. The monitor from this system crash was not affected TIA Mike Eisenstadt Austin Texas PCBUILD's List Owners: Bob Wright<[log in to unmask]> Mark Rode<[log in to unmask]>
