Not sure, but try loading Safe Mode by pressing F8 during boot and lowering screen resolution. In Safe Mode you can even run System Restore. It load to a previous date that you choose.

I was updating my avg when my granddaughter touched a button on the computer. She knew she did but does not know which one. Anyhow, the screen went blank. The mouse appears and I can move around but it...


There are a couple ways to fix this , 1. When you turn on the computer as it's booting up start pressing the "F8" button on your keyboard , your pc should load up to a black screen with several options in white text to choose from , try "boot using last known good configuration" , if that is unsuccesfull repeat the previous steps & this time choose "boot safe mode". If you can at least get it to boot into Safe Mode you can undo / repair the changes that occured .

2. If you can't even boot Safe Mode , you can try booting your pc using the operating system installation disc / recovery disc that came with your pc . Once loaded you can select to repair your current installation . Then sit back & wait till it's done , it will reboot & you should be presented with your login screen .

When cold starting, my comp will run for a few


Its a GPU problem.
It can be overcome by doing reflow technique.
You need to do following.
1. Uncover ur PC casing
2. Locate the nVIDIA PCI-E Card.
3. On the card, locate the power supply pin of GPU fan.
4. Remove the pin.
5. Switch on ur PC.
6. Still u may get scrambled display/wavy screen, but wait for 5 minutes.
7. Press reset button on ur PC.
8. Ur PC might work.
9. Switch it off.
10. Connect the power supply pin back as it is.
11. Power on ur PC.
thats all.

Removal of fan power, makes the GPU to get high heat, it a reflow technique.
Remember, not to touch the GPU portion (heat sink), as it may be in higher temperature.
Try this, it works most.

Blank screen after boot up


Remove the card, plug into your built-in card. Start your PC in safe mode. Uninstall all ATI software and delete the card from Device Manager. Restart. Reinstall the ATI drivers. Power down. Install the card and connect your monitor to it. The OS will find the card in default mode - let it. Restart. When it comes back up, you will be able to select the full range of operating modes.
BACK UP :)

MONITOR GOES BLANK


Did you recently change or install a program that would affect the resolution and card output? Try booting into safe mode by holding the "shift" key during boot. From there right-click on the desktop and hit 'properties'-> 'display properties' -> 'settings' , check your resolution and drop it to 800x600 and then reboot. If everything goes back in normally make sure you have the right windows drivers for your video card. You can also check the driver version and settings while you're in safe mode. Sometimes the windows update drivers can act screwy and I would recommend getting them directly from your card manufacturer.
