Solve : BIOS Screen Crash? |
|
Answer» Whenever I unplug the computer altogether, press the power button to get any power out of it, plug it back in, and power it up, it gets to the operating system just fine. When I shut it down and turn it back on, however, it hangs on the BIOS screen. Do any of my fellow computing fans have any suggestions? I am hoping this will not require replacing the power supply unit or any other components. I would like to have this computer working flawlessly before selling it, and this is the last major problem that I can find with it. Thank you for your time!Quote I am hoping this will not require replacing the power supply unit or any other components.The best troubleshooting method for process of elimination is to replace potentially troubled parts with known good parts and examine if the problem remains or not. While some problems are as simple as not requiring parts to be replaced such as if you had a jumper accidentally across the CMOS reset and keep losing settings and no battery has to be replaced, most problems require something to be replaced or repaired to TROUBLESHOOT or to repair the problem. An old 1950s television repair guy once told me when asked how he troubleshot and what methods he used, that he would drive to the peoples homes with a van full of tubes, resistors, capacitors, switches, etc, and 99% of the time when dealing with a strange problem, the problem was resolved by just swapping out 1 tube at a time from the sockets to see if the problem was resolved when something strange was reported and observed and it wasnt the direct result of 1 tube that controlled say just the audio etc. He could be there all day with test equipment trying to pinpoint the exact part that was bad or he could use process of elimination and have a solution in under an hour. It could be Power Supply or Main Board. Only way to troubleshoot this would be to swap out the PSU and see if the problem remains. If the problem remains then its likely a main board ( motherboard issue ). Is there a specific part of the POST in which the system is hanging such as memory test or hard drive initialization etc to where you know to check the memory or hard drive for issues. There are portions of the main board such as WOL, Soft Power, and other features that operate on most modern computers when they are off and power is still CONNECTED to power supply. These systems will show a lit LED for Network Adapter and sometimes the motherboard will have an LED or two to show its state. I had a high end gaming motherboard about 5 years ago that even had a built in POST Diagnostic LED display and at rest with the computer off it showed a alpha-numeric code which pretty much stated in the code cross reference that the system was at rest waiting to be powered up.The CMOS battery was one of the problems, actually. It seemed to not be keeping the time until I replaced it. I don't have any other power supply units lying around for testing that out. Maybe I will buy a new one sometime. That's interesting. I purchased this computer from someone who repaired televisions from the seventies to the nineties. Thank you for your response!Then just swap some tubes in there...1 at a time.If its a Steampunk Case Mod.... then that MIGHT be a solution... Was looking for the pic I SAW a few months back of a Nixie Clock in an old XT case that someone was using as a HTPC. The Nixie Clock used up one or two 5.25" bay slots. Funny that you got the pc from an old tv repair guy. [recovering disk space, attachment deleted by admin] |
