I'm having trouble getting my desktop computer to boot up today.\n\nI'd left it on continuously for two or three days and finally shut it\ndown when I went to bed last night. When I tried to boot it up this\nmorning, I got basically nothing.\n\nThe fans start immediately but I don't even get the single beep. I'm not\nseeing a Windows logo or even the first screen which tells me what do\npress to get into the BIOS. Pressing F2 does not get me to the BIOS when\nI start pressing it repeatedly from the moment I powered up.\n\nI thought it might simply be that the video cable had gotten dislodged\nbut I checked it where it connects to the monitor, where it goes into\nits extension and where it goes into the case and all connections seem\ntight. I also opened the case and looked for anything that might not be\nseated properly, particularly hard drives, but everything seems to be\nproperly seated.\n\nI'm not very good with this kind of hardware issue so I need some advice\non what to check next.\n\nThe desktop has been working fine since I reseated the SATA cables (see\nmy post in September for details). I'm not sure what caused this latest\nproblem. I have two cats and it's always possible they bumped something\nas they walked around the computer but that's about the only vague\nglimmer of an idea I have.
