I was trying to install Windows 8 on a newly built computer that contained a hard drive with Windows XP on it, one that I hadn't used in about 6 years. It booted XP up just fine. I got a downloadable copy of Windows through my school, put it on a flash drive, copied it to my new computer, and started trying to install it. While it was installing, I left the room for about 15 minutes. When I came back, my monitor wasn't displaying anything, but the computer was still on. I tried turning it off and on again, but it still wasn't loading anything. Externally everything looks like its working fine, and there are no beeps from the motherboard. So far I have tried disconnecting the power supply for several minutes and plugging it back in again, and disconnecting the old hard drive. Neither has done anything, and my moniter still just says "no signal" when I turn the computer on. I have recently been told that trying to update Windows XP to 8 causes problems like this, but I'm not sure what I should do.

IF your HD was disconnected, how would 'Windows' cause the monitor to say 'no signal'? See WINDOWS is just software, it doesn't 'do' things to hardware, your 'test method' (does Windows work) is the wrong problem here, you should be testing to BIOS FIRST. IF you can't "see" BIOS when you turn on the computer, WINDOWS hasn't even loaded yet, so be it XP, 8, HolyGrail edition, won't matter if the COMPUTER HARDWARE isn't working.

REMOVE THE HD, try and turn on the Computer, do you see BIOS? Yes / NO. If no then the PARTS THAT ARE LEFT are potentially the problems and you should follow the BREADBOARD method.
IF YES you see BIOS, then reboot with the HD plugged in, enter BIOS. Does it show the HDD? Does it show the HDD correctly (it says it is the right 'size' drive, etc.). Personally if you have a drive that old (6 years) there is no reason to be using it on a new build. It will be slower, smaller, etc. then a current cheap ($50? for a 1TB 7200RPM!!!) drive.

I would NOT have tried to install W8 over WXP, unless your trying to 'UPGRADE' edition of W8. Otherwise I would download and make a DBAN CD, wipe the drive and try the install over again.

Sorry, should have clarified about the no signal message: that was displayed by the monitor itself, not the computer. The "no signal" message wasn't caused by the computer, it just let me know that the monitor wasn't responding to the computer. I do not see BIOS when I boot it up.

Yes I am aware of what the message means and when you see it was important. As your NOT seeing BIOS when you boot up has nothing to do with Windows, as I said, it is a hardware issue, not a Windows issue. Always make sure you can get to BIOS first on each step before you worry about Windows (Windows is the VERY last thing to deal with when doing a build).

That you can't see BIOS is a hardware issue, so lets deal with the hardware. When we BREADBOARD we are being VERY repetitive and anal about what we do, but it is the only way to determine which 'part' is at fault. My first test was to see if this 'drive' could be a problem (did it short the mobo, does it cause a failure, etc.) so my first question, when the HDD is unplugged from the system completely can you get to BIOS or not... then I had the next step, you haven't stated what happens NOW with the HDD unplugged.

If unplugged it still doesn't POST to BIOS, then the next step is we dont' know WHAT is causing the hardware to fail, so we need to do the most simpliest way 'it turns on'. This means TAKE EVERYTHING OUT of the case (Yes is a hassle but there is a serious reason for all these steps). Now dismantle ALL parts, taking everything back apart.

Get the Mobo box or a piece of wood, place ONLY the Mobo on it. Now seat the CPU, 1 RAM stick ONLY, if it has onboard video plug the video cable to the monitor from the onboard video. Now run the PSU ONLY to the MOBO, and the ON/OFF switch from the case to the Mobo, can you get to BIOS? If NO then these are the main culprit pieces.

IF it doesn't work at this point then the steps are to 'cause' a error beep code, remove the 1 RAM stick does it BEEP code a problem with the RAM? Yes / No? If NO then there is most likely CPU/ Mobo problem OR PSU.
Then Do CPU, dopes it beep for problem with CPU? Yes / NO ? Now your down to Mobo or PSU as failure.

THere is many steps here, let me know where we are at here and we can determine the next step

I found the problem - turns out I had some faulty ram sticks. Thanks for the advice!
