|I run XP. Don't know if this is a hardware issue or an OS issue or what, really. Don't hurt me.|
When I turn on my computer, the lights go on and all of that. Fan goes on high immediately (I cannot remember if this is normal or not). The keyboard lights up as usual (first, a flash of all three lights, then they go off, as normal). I never get a post screen, never get any kind of screen actually, power light on monitor stays yellow rather than turning green (yellow means it is powered on, but that the computer has been turned off). Also, the light on the dvd drive and the light that indicates hard drive activity do the same dance over and over, indicating a loop.
Cannot get into safe mode. No screens at all, no beeps, and pressing keys is completely ineffectual.
Hitting reset makes no effect. I have to hold in the power button for 5 seconds now before computer will turn off (it would immediately begin shutting down when you pressed it before, but I seldom did that, preferring instead to do a proper shutdown). There is not a disk in the machine. There is nothing but the monitor, keyboard and mouse plugged into the machine. I did not make any recent changes to the registry (did once a year ago to get rid of a bad disease, as per directions), and haven't recently installed any programs. When I put an OS disc in, it changes nothing. No screen, no activity from dvd drive, except the light, which continues its looping dance uninterrupted.
After this started happening, I opened my machine, cleaned dust out, took out and reseated memory, all cards, plugs, etc., cleaned heatsink on processor. No change.
There is only one thing that I can remember that might have possibly had something to do with this: I forgot that my computer was disconnected from my cable modem, and I clicked on internet explorer, to connect to internet. Well, of course, the machine couldn't connect, and I got the retry message. I clicked retry maybe 5 times, and then the computer froze. No keyboard shortcuts would work, mouse ineffectual, pointer frozen. The reset button did work that time, but when the computer tried to start back up, this mess started. After that, reset button no good.
Given all of this, what seems the most likely problem?
