no response on monitor

[jdh2118]

Recently, while restarting my computer, the screen froze and then shut off. Now when i try and turn my computer on, all of the lights and fans spin, the harddrive turns on, but there is nothing on my screen. Also my keyboard and mouse and anything else plugged into the USB doesn't give any sign of functioning. I had a problem with the exact same symptoms a couple months back when i was switching cases, and it turned out to be a problem with the ram. I have 2x 512's with a 667 frequency and another 1x1024 with an 800 frequency. Before, i fixed the problem by starting the computer with the 2x512's, and then putting the 800 in after. i have tried restarting with every possible ram configuraton, i'v reset my cmos multiple times, and still i get nothing. I'm not sure if its a ram problem this time or a harddrive problem or something else, but it gives the same sympoms as the previous ram problem but isn't fixed by how i used to do it. Any help would be greatly appreciated!!

Does it work in Safe Mode?

 

[jdh2118]

i cant get it into safe mode unless theirs a way to do it without choosing it from the startup menu?

I have not used Vista yet. Found this-

To get into the Windows Vista Safe mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu. Use your arrow keys to move to "Safe Mode" and press your Enter key.

Note: With some computers if you press and hold a key as the computer is booting you will get a stuck key message. If this occurs, instead of pressing and holding the "F8 key", tap the "F8 key" continuously until you get the startup menu.

thanks, i'll go try that, the only problem though is that when i boot my computer, i dont think it recognises anything in the usb ports, so idk if my keyboad technically works upon boot

nope that did nothing, nothing even comes up on the screen but all my fans are spinning and the harddrive is working,

I am wondering if your monitor or video card died. Can you try them on a different PC or get known good ones to connect to your PC? Good cable connections, reseat video card.

 

[jdh2118]

it could be the videocard i guess, i know it's not the monitor cause i tried it on a different computer and it worked fine, the fan spins on the card and it's the only place i can plug my monitor into, theirs no place to put it on my mobo

reseat the video card and verify that all power connections are plugged in and secure.

 

[jdh2118]

how do i reset the video card? just take it out, let it sit, then put it back in?

 

[law9933]

Yeh, remove & reinstall. All power off of course, grd yourself for static.

 

[jdh2118]

yeah i tried that and got nada, im just gonna assume i have a single faulty part, so now i gotta isolate which one it is i guess

 

[robisbell]

I'd try the video card in another machine.
