What might be the reason for my PCs inability to boot up. The power comes on alright but it does not boot to load files and so nothing comes onto the monitor. I've tried so many means but still. Initially, it will eventually boot up if you leave it on for a long time for it to get heated up. But now, it will never boot up even if you left it idle for the whole day or night. I am using the Intel PIV D845PEBT2 mother board. Please I will be someone could kindly help me out.

The most common reason a computer won't start can be a piece of hardware has failed or is causing a problem but that hardware isn't usually a hard drive, the part of your computer that stores all of your files. To fix such kinds of issue, you can take the following steps.1.create a bootable usb or cd ,there are kinds of software for you to complete this step, you can choose Fix Boot,EasyBootDisk or Windows Boot Genius. I suggest you to use Windows Boot Genius, it is easier and more effective.2.boot your computer from the created disk3.fix the issue after run the softwareBy the way, before any further steps you should make sure the power supply is good. Any hardware issues such as pc power and cable,motherboard corrupted should be troubleshooted.I don't suggest you to try the solution above until you are sure there is nothing to do with the hardware. source: http://windows-8-password-recovery.com/computer-wont-boot.html
1. The BIOS setting for the boot device is not looking for the correct boot disk. This can happen if the modified by software or by a user unaware of the impact.
2. The BIOS battery may be dead, causing the machine to default to factory settings.
In either case above, reboot the machine, press the proper key to access the BIOS and verify that the proper device is selected as the boot disk and is first priority for boot.
3. The hard drive may have failed. The only solution here is a new hard drive, and a system reload/restore.
4. The OS may have gotten corrupted in the boot sector. TO fix this there are a few things that can be done, but for someone with little knowledge of PCs, this is dangerous territory. You can boot to the OS disk and go to the Repair Console, and attempt to do some fixes, such as CHECKDISK, and fixing the Master Boot Record (MBR), but these can result in total inability to recover. Best if you get to this point if yo can find a friend with some experience here to help.
If I understand you well, before Windows loads, you get a notification about the ethernet controler. If this is the case, then you'll need to go to BIOS and change the boot options, so that your hard drive is set as first boot device, then DVD as second boot device, then USB drive as fourth boot device, and lastly LAN as fifth boot device. What happens is that your PC thinks that the LAN is the primary boot device, and in corporate networks PCs bet such a setup so that there's one large server feeding data to the local cubicle PCs to such extent that these cubicle units are just "dumb terminals". In your situation, your PC thinks it should too get boot infro from the LAN, but as your PC is not a part of a corporate network it waits in vain, and after a while it moves on to the second/third boot device, and then finds that it has Windows installed localy and starts loading the OS. So, to wrap up, you'll need to go to BIOS and set your local hard drive as the primary boot option.
If this was informative please give it a Thumb Up. Thank you.
Ubuntu works with RAM and CPU Memory instead of a pc like xp that uses Virtual RAM. If the pc that could not load ubuntu doesn't have enough ram to support the reading of the Hard drive and the Operating System then it won't work and Xp will only run on the computer that xp was installed onto the hard drive.
If your system is still not holding the date and time after changing out the CMOS battery, then ther is what is called a "cold" solder joint on the motherboard thjat might work, as you mentioned, after the system is warm. However, sicne the system does boot up and operate later, it is more likely that the power supply has the issue and is not delivering power properly until it stabalizes. Get a replacement PS, just make sure that it has at least the same wattage as the original one. You don't even have to physically install it at first, just swtich all the connections from the old one to the new one and see if the system comes up right away. It is does, then do the swap. If not, you can return it and replace the motherboard.
