Hey.. Im really not quite sure if it's overheating, or what is going on.. First, I'll start by info on my computer.. OS: Windows 7 CPU Type: Intel Celeron, 2600mhz (26x100) Motherboard Name: Dell Dimension 2400 System Memory: 1536MB (PC3200 DDR SDRAM) Motherboard Chipset: Intel Brookdale-G i845GEV Well, also, let me say.. I've had this computer for awhile, but I only play Virtual Pool 3 on Gamespy. Ever since I got it, it's been working fine for me, on and off the internet. Now, for some reason, about a week ago, my computer has been shutting itself down.. All the LED ABCD lights in the back turn solid orange, and so does the button to boot the computer (start), but the light inside the computer stays green... Also, when it shuts down (the fans are still running and everything).. So, I have to shut it down myself and restart it.. It's like it goes into hibernate mode (but its not, because I have all that stuff turned off, since I got it.. But yea, just like that.. Fans still going and etc.. It's been doing this alot since it started.. I tried to shut the computer down, unplug it and hold the button in for 30 seconds.. I tried replacing the power supply.. I even replaced the battery.. But nope, nothing has worked for me yet. Please, if someone can, help me... I have EVEREST Home Edition, and see nothing wrong in there either. I have the side of my computer open, too, with a fan near it, still not changing anything..
