I have looked over the boards and seen quite a few cases of what I appear to be going through. I have an idea of what could be causing it, but a number of things don't seem to make sense, so I'll post my story and maybe someone can shed some light:
My computer has been up and running for quite some time, couple minor problems here and there, but nothing too crazy. I haven't made any hardware changes whatsosever in a while.
Today I was installing some software, and the installer decided to stall. Everything else was working, but I did a hard reboot because I couldn't end the process. I try to switch my computer back on after that, and my screen is blank. Leave it a few minutes try again, same deal. However, if I leave it to boot, everything is working (i.e .if I type my password in, I hear the Windows login sound), but just no graphics. I assume it is a problem with my graphics card, so I unplug, open up my case, and reseat the card.
I plug everything back in and hit the power button. Now, it turns on for a fraction of a second before turning off, then back on, etc. It keeps doing that until I hit the kill switch on the back of the PC. Even after doing that it still turns on then off one last time, until the green light on the mobo turns off.
I have since unplugged everything non-essential. The only things in it are the power cables and the CPU. I turn it on...still same deal. I fiddle with it a bit to make sure I didn't miss anything stupid (sticking power button, power cord on mobo loose, etc). Everything looks fine, but still nothing. I take a break and come back a little later. Hit the ON and suddenly it turns on...for about 10 seconds, then right back to the On-Off routine. I try it again 2 minutes later, not a whole lot change. I give it 15 minutes, and suddenly it turns on for a good 30 seconds, and then off.
No beeps. Nothing else. Does this sound like overheating? How could it be that it just suddenly decided to act like this, when not 3 hours ago it was working a treat? If it was an overheating problem you'd think I would have seen something dodgy in the last few months, but its been perfect.
So, what are my options? Does it look like overheating? Is this a matter of giving it some new arctic cooling thermogel, or is there something I am completely missing here?
