Red and green dots after boot up

post #1 of 18
Thread Starter 
This morning I started my computer and it was fine. Turned it off after checking mail. Turned it back on in the afternoon only to see that after booting up, red, white and green dots started appearing towards the top of the screen.
The very first thing I did was to restart the computer, followed by selecting 'Last known good configuration' option, and finally safe mode. In all of these, the dots were appearing (even in safe mode) and the screen froze in as it is. I though it was a memory problem, so I removed the memory, switched with a spare one, but it didn't work. I cleaned my computer and still it didn't work. The strange thing is that when I opened system restore, and even when I ran the Windows setup from my setup disk, everything was appearing fine on the screen (no dots, artifacts or graphics corruption). I thought it was a software problem so I even managed to do a system restore but it still didn't work.
Finally, it started working all of a sudden. I don't have any spare money lying around and the whole drama gave me a minor heart attack. Can anyone tell me what could've caused this problem? Is it the graphics card (I don't think so though, because everything else is working fine). If you do think its a hardware fault, can anyone also tell me the total warranty period of an XFX graphics card? I bought it less than 2 years ago and have registered it on the XFX site as well (that gives me 5 years warranty, right?)

Any help will be highly appreciated. P.S.: I use my computer very sparingly, and have never overclocked it (and ironically, I've posted this on overclock.net, anyways thats not important)

Processor: AMD Phenom II X4 955 @stock
Memory: Corsair 2 GB + 4 GB @stock
Graphics: XFX Radeon HD 5870 @stock
Power supply: Cooler Master GX550
Motherboard: ASUS Crosshair IV Formula
Then the usual business, SATA hard drive, optical drive etc.

Try putting it under stress watch temps and also report if it starts having these issues again. And post the results back in response. I had one that as soon as I got it the card was having issues with it. I ended up having to send it back to the manufacturer.
Thanks, yodazb

    When do the "dots" first appear?  While Windows is loading (black screen with Windows logo on it)?  Soon as the mouse appears?  After the login screen appears?  After you log in?  How large are the dots?  Pinpoints, or larger objects (if so, how large)?
    If they appear after you log in and they are not pinpoints, I would suspect malware first...  Also, overclocking the video card memory can cause screen corruption, but usually it appears randomly all over the screen.  Is your system usable like this, or does it always lock up?

Thanks for your reply. I actually use a program called EVGA PrecisionX and I have programmed it to run the GPU fan at 100% when the temperature is around 70 degrees C. Do I run a stress test without this software (so fan is controlled by the firmware as it is) or do I use this software for a real life situation on how I use the card?

Return? Do you happen to have any knowledge about XFX cards warranty? I think its 5 years (am I right?)

I have actually disabled GUI boot from msconfig. So I don't have a correct idea as to 'when' exactly. But I'd say as soon as the 'Starting Windows' screen is done and the mouse pointer and the login screen come, thats the point. I didn't actually see the login screen. But the dots appear when the booting screen is almost done.

I'd say that these are the size of individual pixels, so yes, pinpoints. But they're rendered at 640x480 (and my native resolution is 1920x1080). This also leads me to believe that these points actually

As I had mentioned earlier, I never overclock my system (ever!). And no, this is the first technical problem I've ever had. Before this, the usual suspects like BSODs and crashes, yes, but nothing as peculiar as this one.

Run anything like furmark, heaven, 3Dmark, etc. Just programs to stress it. You can leave your application running, and I'd advise it if your card is warming up like that. I know it's a obvious question to ask but have you tried re seating the gpu? Regarding your warranty questions, check this link:

Let me know what happens under stress and what temps you get to.
Thanks, yodazb

    Try reseating the video card (i.e. take it out and put it back in); the pins on video cards are very close together, and sometimes the pins can get misaligned if the card is not resting flat in the PCIe connector.  Also, make sure that the video card is completely clean of dust; vacuum it if it is dirty.  When vacuuming things like cards and memory, it is best to be working on a grounded, metal surface.  Many chest-style freezers have metal grounded lids that work well for this purpose.
    Just to see what happens, try programming EVGA PrecisionX to run the GPU fan at 100% at 60°C and see if it makes any difference.

Thanks for the helpful replies. I was a little occupied today but I'll start the Furmark test and post the results right away.

Well, the warranty I checked was two years. I think I have just finished two years so that leaves me penniless on the thought of replacement.

Yes, I had tried re seating the graphics card and had also cleaned it. But I didn't put it in another slot. The problem was still there but it automatically went away after some time. And since the card's working all fine now, I don't really know what could've caused it. I think I should continue to use it as it is now, and freak out if it should happen again.

If you do end up having these issues again I'd try bumping up the voltages slightly with a program like MSI afterburner.

Increasing voltage can solve this? I'm a little curious now...
