I have a similar problem to other posts that I have read on this forum regarding the no input signal message
on my monitor & i have tried a couple of the possible solutions but with no luck & so desperately need some expert help. My trouble started after installing a sapphire ati radeon hd 2400 pro 512mb X8 agp graphics card, the display & sound stuttered so i looked to my mobo manual for tips on improving performance & made these adjustments:1:set internal cache to enabled 2:set bios cacheable to enabled 3:set 32k shadow to enabled 4:set fast command to ultra 5:set fast R2R turnaround to enabled 6: set the agp fast write to enabled & the aperture to 256, at this point my monitor went blank & nothing i have tried makes any differance, to date i have tried clearing the cmos/ changed the psu as on checking found it to be 250watt,
i put in a 500 watt psu still nothing/ disconnected everything from the mobo nothing, i hope this explanation is not too long winded my system is as follows:MSI-MS 6775(V1.X)atx mobo,WD caviar 160gb HD,
2.5gb kingston ddr ram,sapphire ati 512mb agp graphics card, creative x-fi extreme fidelity sound card, Optiquest Q241wb monitor,DVD burner & DVD rom, floppy drive, 500 watt psu & the os is xp/sp 2.
I would appreciate any help if possible,
