Question about Dell OptiPlex GX280 PC Desktop
Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.

Diag Lights 3,4 indicate memory Failure (this could however be a motherboard or Power supply issue) see the manual on support.dell.com http://support.dell.com/support/edocs/systems/opgx280/en/ug/tools02.htm#wp1114558
1 - test memory - running on a single stick of memory and moving the memory around.
2 - test Power supply - swap with a known good PSU if possible
3 - Check for bulging capasitors on the motherboard (seems to be relatively common on these boards)
Hope this helps
