video startup problem - monitor appears about 10-15 sec. and shuts down "dpms off mode"
Posted on 2003-03-09
Hi, I'm trying to troubleshoot a video startup problem.
at bootup, everything sounds and looks normal (normal 1 beep) but after about 10-15 seconds at the same point nearly every time (just after Windows logo screen) my monitor changes a green light to an orange light and the "DPMS off mode" message appears.
- reseating graphics card
- installing a new graphics card
- swapping monitors
Bad motherboard?? This is a Systemax pc, nearly 3 yrs old, existing motherboard: "Socket A ATX Motherboard, 1-4X AGP 5-PCI"
Also, my 56k modem quit working a few weeks ago (only use it in emergencies since I have a cable modem) but wonder if that was a warning of a meltdown... also my computer is now making a few intermittent "straining" sounds!!
If this is the problem, how difficult is a motherboard to replace? This is a 1GHZ computer, 128 RAM.
THANKS FOR ANY HELP!!!
