cant figure this out

[luby70]

so my comp bugged out the other day. i turned my monitor on after it being off for a few hours and i had columns of white rectangles all across my monitor. so i shut my comp down for a while cause i thought it might just be cause it was on for so long. after 7 hours of being off i turned it on and everything was fine, so i went to bed and shut my monitor off. when i woke up i had the white columns again all across my monitor. it has been like this for a few days now and it wont go back. i was wondering if anyone knew of any viruses or spy wear or ad-wear that can do this or is it possibly a hardware issue. also before you ask i have a video card that my monitor is plugged into and i think that is what it is but im not sure and i cannot find the converter to plug my monitor directly into my motherboard to bypass the video card. also when i turn my comp on and i go into the system screen its all messed up, nothings in the right place and i cannot see what is what. last but not least, when i start it up and it goes from the boot screen to the windows loading screen it actually goes to a random screen first with columns of weird letters and number and the screen is blue purple and black.


any help ideas, or suggestions would be great seeing as i built my comp myself and i like to fix it when it breaks.

Sounds like the video card. Open up the case and make sure its seated well in the slot - it would be a good idea to pull it out and then place it back in the slot to reseat the card. Also while doing that examine the video card, make sure the fan and heatsink aren't really dirty, and then watch if the fan works on the card when you start up the computer - if the card overheated then that could be why you're seeing the screen corruption.

You cannot plug your monitor directly into the motherboard unless your board has onboard video. If you did have this option, then you must remove your video card in order to use the onboard video.

When you pull the video card, do be careful. There is usually a plastic lock that must be pushed/moved in order to remove the video card.

If you are getting this corruption on the bios screen or during post, then it is a hardware problem and not a virus, malware.

I assume you have tried another monitor OR tried your monitor on another system to test.

ya i have tried a different monitor and mine on my friends computer and i know its not that so i guess ill check out the video card.

so i just got back from my work trip and i removed my video card and looked at it, everything seems fine and its not really dirty but i am still having the problem and new ideas?

Even if it looks 100% fine, it still may be broke. Best way to find out is to try the video card in another computer or have it tested.

ya that is what i was thinking, but my video card is agp and i dont have a PCI express slot so i need to see if anyone of my friends has a agp slot video card so i can check it.
