URGENT HELP NEEDED

[NukaCola]

Okay, so yesterday I came back to my dorm in college and hooked my PC back up. Everything was fine, up until I wanted my PC to go into Standby. I clicked Standby, and nothing happened for a good minute, so I tried hitting it a few more times, then I just hit turn off. Everything wast hen getting ready to exit Windows, but then it was stuck, only my wallpaper was visible, everything else was gone. I decided to manually turn off my computer.

So I reboot, everything's fine. Standby is still giving me problems, so I just leave it, and after a couple minutes my computer finally hits standby.

Now, I turn my computer back on from standby, and the system starts saying "Shutting down Windows" probably because I hit Turn Off after Standby again so it queued up the request. No biggie, I turn my computer on again. Now, when Windows boots up, I'm suddenly getting artifact and weird specks that mess up EVERYTHING. Text is illegible, some things appear clear and line/spec free sometimes, but then they revert. I took a screenshot but I dunno if you will see what I see.

Please help me, I don't know why it's doing this..I'll try reconnecting my DVI cable from my GeForce 7800GT to my LCD Monitor...

Sounds like your graphics card is either overheating, or has clapped out...try upping the fan speed with rivatuner, or take the side of your pc off and blow a fan into it. If the artifacts go with either of them, its a cooling problem. If not, then its been running too hot for too long, or has been overclocked too high for too long. Is it overclocked? Does your pc have good ventilation anyway?

Yes, my case ia Thermaltake Extended ATX with around 3 or 4 fans...I don't know what rivatuner is, but I DID download an overclock program called "ntune" but I did not use it at all.

Also, I just restarted my computer and the artifacts seem to be gone..what the heck?

EDIT: Also, can anybody explain why my Standby isn't working right?

 

[Syntax Error]

Standby does NOT constitute turning off the computer, a current still goes into the system and some components within are still on. I recommend going into Hibernate or just plain shutting down, it sounds like while your computer is in Stand By, you're risking your components running in the background and overheating that way.

have you tried safe mode? if it happens in safe mode, its probably your video card.

Okay I downloaded SpeedFan and it seems like my graphics card's fan is the culprit, the thing is warmer than it usually is:

I have a big fan that's blowing into my PC right now..I guess I should take my graphics card and have a look at it? How do I run safe mode again?

43 degrees is fine for a video card, thats nothing to worry about


find out how hot it is getting during gameplay, if its exceeding 90-95 or so it may have a problem

Get rid of nTune - that program is EVIL.

Try RivaTuner instead. :beer:

Yeah I've got Rivatuner. I'm uninstalling nTune as we speak. Thanks for all the help, everything is alright now.
