I have a PIII 5000mhz on an ABIT BE6-II m/board with 512mbs PC100 SDRAM - 250w ATX PSU -Creative 8432E CD-RW ,Sony DVD-ROM,GEForce 2MX 32mb graphics card,Yamaha SW1000xg s/card & US Robotics voice winmodem.
When currently switching on the PC,at first the cd-rom leds flash and the Creative CD-RW led nearly always stays on -the monitor goes to standby mode and the pc won't boot at all though the psu fan is clearly audible.I can't switch off using either the power-on or reset switches,only the on-off switch at the rear of the case(though the power-on switch works for the initial switch-on and reset works too once the O/S has loaded).After a few goes of switching on-off-on in this way eventually the pc will boot normally.
I notice that always when the Creative CD-ROM led stays on the problem occurs - if for some reason the led just flashes normally a few times then goes off,the problem doesn't occur but I can't seem to figure out the cause.
When I first installed the M/board with my current hardware setup,things ran fine for over a year 'til now.
This problem appears to have arisen out of a previuos problem where the pc booted normally but upon reaching the Win98se desktop would automatically reboot..continuously - until I disabled ACPI in the BIOS.
n.b. -since disabling ACPI in the BIOS,IRQ 9 is no-longer available despite using the manual configuration options in the BIOS.
I don't know if all these problems are related but as they all seem to have occured together it seems logical to assume they are.
Once the O/S eventually loads the PC appears to run with no problem at all though if I need to reboot for any reason I nearly always have to go through the whole problem again.
I bought a new PSU (cheap 350w P4-ready version) but though it comes on I can't get it to boot the pc at all.Are there any known compatability problems between older m/boards and newer psu's?I enquired when I bought the new psu and was told that it should work fine.
Any help would be gratefully received...thanks
