Question about PC Desktops
What version of windows ... start in safe mode does it still happen... does it shut down or reboot ... most common cause of this issue is a driver conflict ... if it is not a driver conflict check the display drivers ... if updating or reinstalling display driver does not work it may be the video card ... if the video is integrated install a expansion board vid card and disable the onboard video ... if the card is not integrated remove it ... restart ... shut down and replace it then boot again ... if you have a newer system check the video card fan which may be $#$@ up and overheating ... if you cant trace it to hardware try using a boot cd .. one of the linux cds ... if it is ok with an alternate OS try doing a OS repair on windows .. the other possibility is a memory issue if it is a cheap mobo with shared video ram...

I have a similar problem:
I have a Compaq Presario SR2010NX desktop computer. Recently, very occasionally, the computer would freeze and the screen would scramble. It almost looks like someone chopped up the picture on the screen. Then we would have to manually shut down the computer and restart. It would always work fine afterwards.
Yesterday the computer did it again. It restarted fine but when my boyfriend tried to install a new mouse the computer froze again and the screen went scrambled. Well this time it did not start back up. I tried to unplug the computer from the wall and restart but that got me to the COMPAQ screen and then the computer froze again and the word compaq was doubled all the way down the screen. We continued to try to start it in PC recovery but it would get the the program and freeze. I actually got it to run once but I couldn't see what it was doing because the screen was scrambled.
Now we have restarted it so many times that it will start up, light turns green, and stays green. The computer sounds like its starting up and it seems louder than normal. The computer doesn't do anything and the screen is black. The lights on the keyboard do not turn on but the light in the mouse does. The CD drive will light up and run as well but nothing happens after that. I can't see the cursor and the keyboard does not work.
I opened the computer up, cleaned the dust off, tried to re-install my old RAM and that did not work either. I disconnected the CD drive but that did not work. Tried to start the computer with nothing plugged in except mouse, keyboard and monitor and that did not work.
I don't know what to do! Help!
