Solved Computer won't load windows.

November 4, 2012 at 16:45:54
Specs: Windows 7, AMD
When I start my computer, I hear the motherboard beep, and I can see the start screen (ASUS), and can also access the BIOS screen pressing F8, although it never gets to the Windows 7 start screen, because almost immediately the monitor goes blank save for a temporary dialog that says no video signal input. The fans are all still spinning, lights are on, etc., just no signal. After that, I cannot restart the computer unless I unplug and let it sit for some time before replugging and hitting the start button. I also tried loading into safe mode but no dice, it just restarts. I put in my windows 7 install disk and it loads up but soon as it gets ready to load it my screen goes black.

Are the fans working on it, especially the cpu fan(the one on the board)? Sounds like it could be overheating. You can also test the power supply with a meter to make sure it has steady, correct voltages. Is the fan spinning in the back of the power supply? Could be an overheating north bridge, or graphics card.

Sounds like the video card or on-board video chip are having issues. Either the card is fried or the chip is. I would try getting a new external video card for the machine. This will either replace the existing card (if it has one) or it will replace the on-board video with a simply change in the BIOS settings. If this does not fix the issue, then it could be the processor, motherboard, or memory that is going bad. In this case, you may be better off just replacing the computer.

If you press F8 to enter the BIOS setup and just let the machine sit on the BIOS screen, does it still shut off the screen after a bit?

All fans are working fine. The computer was just working a day ago. A new power supply was just added because the other one went out. After replacing the power supply everything was working fine and dandy. Then today nothing will get past the very instance of the the loading windows screen.

After pressing F8 the computer sits fine on the bios screen.

First, please list exact detailed specs on your system including make and model numbers. Include all added or changed hardware like the new power supply and if you changed it, your video card details. On the power supply, list not just the make, model, and wattage, include ALL of the listed (label on side of power supply) Amperages for each Voltage that is shown.

In BIOS, list the shown Temperatures.

In BIOS, make sure CPU and Memory specs are listed correctly and time and date have not suddenly changed.

Run Memtest via a bootable CD to test your memory for errors.

How long has the new power supply been in use?

What other changes (either hardware or software) have you made recently?

Has the system behaved unusual at all recently?

Post details, results, and answers to all above and we can begin to analyze your problem properly rather than just guessing.

You have to be a little bit crazy to keep you from going insane.

For starters, you listed absolutely no system specs.

"A new power supply was just added because the other one went out"

What makes you think the PSU "went out"? What is the make/model/wattage & amperages specs to both the old & new PSU? Did you buy a quality replacement unit or a no-name cheapie?

"I put in my windows 7 install disk and it loads up but soon as it gets ready to load it my screen goes black"

You have a hardware problem or BIOS configuration problem, not a software problem. Put the Win7 disk away.

"no video signal input"

Should be self explanatory - no video signal is being sent to the monitor by the graphics card (or onboard graphics). Once again, this is a hardware problem or BIOS config problem, not a software problem.

"I hear the motherboard beep"

Single beep or numerous beeps? A single short beep indicates the board passed POST. Anything else indicates a problem.

After pressing F8, try these two things. First, select "Last Known Good Configuration" and see if Windows loads. If not, reboot, press F8 again and try going into safe mode.

and can also access the BIOS screen pressing F8

Are you certain you mean the BIOS screen? F8 mostly takes you to the start menu where Safe Mode etc are listed. Without the specs it is tricky.

Whatever, getting to the BIOS screen is important because if you can't get there it is certain to be a hardware fault.

Always pop back and let us know the outcome - thanks

All: Please wait for the OP to reply with detailed specs.... Anything else is just guessing.
