This is my first post. I've been a long fan of BleepingComputer.com but I have never needed to ever post something because the wealth of information here was able to help me resolve most problems. That is, until now. I have been fixing computers for years and I don't remember to have ever been in a position where I have exhausted all options and have surrendered to the reality that it may be the motherboard. But, despite my experience, I know I'm a novice at this game so that's why I'm turning to the people here.
I have a Lenovo ThinkCentre M58 7244 Desktop. This is not mine, but a friends. The problem is as follows: When the computer boots up, there is a splash screen which says the "system is starting" and to interrupt the startup, I can hit enter. If I hit enter, screen disappears and I'm brought to a black screen with the cursor blinking on the top left corner. Clearly the issue is startup related so all I'm thinking about is trying to fix the MBR or even considering flashing the BIOS. So, I attempt to get into the BIOS. Since hitting enter brought me nowhere, I decided to use other common hot keys. Hitting F1, F2, Delete, F8, F12 from the splash screen take me nowhere except to the blinking cursor. I hit ESC and viola! Another screen that displays lots of text as well as memory information, which is all accurate.
This screen also gives me two additional options: Hit F1 for setup or F12 to enter Startup Device Menu. When I hit F1, I get a familiar error message: "PXE-E05: The LAN adapter's configuration is corrupted or has not been initialized. The Boot Agent cannot continue.". The error sticks around only for a few seconds, then disappears and we're back to the blinking cursor. When I choose to go with F12, it says that it is going into the boot menu, but after the screen disappears, it takes me back to the blinking cursor. Aside from this, you should know that I've attempted using basic hardware configuration, which has done nothing.
When the computer boots, the power seems to be going everywhere. All fans run, albeit a little too fast, but run nonetheless. CD drive has power therefore I assume the hard drive is getting power as well. The display obviously gets power. I tried to isolate the issue by removing one hardware component at at time until only the basic components remained (power, one memory stick, keyboard, display). Same results. Also, you should know that I have heard no beep from this computer in all of these scenarios. Oh, and I've tried to clear the CMOS using the jumper.
The machine is totally locked me out and I can't seem to think of any other troubleshooting technique I can employ. Either I'm overlooking something big that I needs consideration or this computer is gone. Still, given the state of the hardware components as well as being able to get a display, sounds like there is definitely hope. But I can't wrap my mind around how I can get to a point where I can boot from a removable media. I just can't get there! This is driving me nuts!
Any help would be much appreciated!
