|Thank you for your response.|
My PC has been running great until Sat. night when I hit the “sleep” button on my keyboard. I could not wake it up so I had to do a “soft reset” but that did not work, so I did a “hard shut down”. When I powered back on this situation occurred: After POST one short beep then screen goes black.
I was able to get through POST and into BIOS (all viewable on my monitor), I discovered BIOS was not configured with a “wake up” so I configed then reattempted start up. After several attempts at resets, I began online research and followed all the advice to no avail.
After POST one short beep then screen goes black. I have tried CMOS reset, removing the battery and Swapping RAM, replacing RAM with new- but the same issue occurs. Everything seems to be working on the MB, all fans, HDD's, etc. I am able to get into BIOS and I am able to view POST and BIOS on the monitor. The monitor seems ok since I can view POST and BIOS. All connections are good. I think the graphics card is OK (that is what I run my DVI output with), and is seated properly.
I am running an ASUS P5B-VM SE Mainboard,American Megatrends. I have the Vista Home addition Operating System. My PSU is a new Thermaltake Purepower ATX 12V 2.0 (600watt). I have assured that all cables are seated properly. I changed the Graphics card today and the system reactedthe same except for now, instead of a black screen, I have a black screen with a flashing white cursor in the top left hand corner.
I did not replace the CMOS battery, just removed. I did switch the jumpers from 1 & 2 to 2 & 3 then back.
The computer does not seem to be running. In the past after the initial boot, I would have a redlight that would flicker as it was loading the operating system. That is no longer happening.
