Computer turns off when turned on! I think i know the prob, idk though( Page 2)

Okay so far i''ve made new threads but they've all been locked so i guess im gonna stick to this one so i might as well edit this post.

i'm sorry if im repeating things but as you can imagine im feeling so bad right now its not even funny... Joshua i'll try and explain in detail but if theres anything, i mean anything you need to know tell me and i;ll find out.. Okay it was working perfectly till i download 2moons, found a trojan got rid of it with Avg, after about 5 scans of just cookies there was nothing anymore. I tried to download Runes of Magic overnight i come home from school and find the download stopped at 1.4gb and all the temps were fine. I try it again the next night come home and it stopped 9 minutes short at 3.8/3.804Gb or something like that.. So itried to download Crysis Patch+ fear this time and when i come home and i find the computer off.So next day try todownload onlythe Crysis Patch(from ea download manager)I turn on the computer and it wouldn't turn on. Somehow it started after 10 minutes i looked inside the case, cpu fan and Gpu fan weren't runing i didn;t know what was going on. I tried to tighten every possible cord in there, and i took out the heatsink and saw paste and that the cpu looked fine and not burned. And there was no funny smell. I put it on and the Pushpins were driving me crazy ( not sure if i installed it correctly). I turn on the computer and i find 2 red lights on the Gpu and my motherboard lights that are usually on has like 4-6 different ones with diff colors red,green,yellow idk what else were off.. Turned it off immediatly, tighetn the psu cord to it and turn it on and everything is running ( with all the lights on the motherboard). I look at temps and The Gpu is stable and all of a sudden the Cpu jumped to about 68C or something like that and it was at startup. I immediatly Turned off the computer And now im waitting for responses on what to do. My specs are Gigabyte P45,Wd 320gb Harddrive, 4gb Corsair XMs2, Intell Q9400(stock fan), Xfx hd4890, Corsair 750TxPSUand CM690. IF you guYS nEeD ANY INFO JUST ASK AND I WILL FIND OUT.

Edit #1 : Here are some pics i got on my last boot up - http://img4.imageshack.us/gal.php?g=p1010309m.jpg.. I also added some ino to my story. That's everything that happened and im 95% sure thats the order i might of screwed up the order of something since this has happened over the last 4-5 days,

Edit #2: Forgot to say i also replugged the video card after taking out. ( This happened right before i reinstalled the heatsink the second time.

EDIT #3. I forgot to say something tht happend. Idon't remember i think this was when the comp wouldn't turn on and i oppened it up. I tighteed something and all of a sudden in a couple secs i see the psu fan and the blue led front fan(and liht up)move about 720 degrees and stop andrepeat till i unplugged the psu i think it was. Also added my psu and my case.( not to confuse anyone i meant add them to my specs above). On the day i tried downloading the Crysis Patch i also got a Windows Update trying to install a Malicious Removal Tool and i installed it.

You pressed the power button in your sleep?

Maybe power fluctuations or overheating?

My guess is you get nnoyed with it's fans and turn it off in your sleep or just kick it by accident?

Maybe power saving options?

check the power saver options in vista, when the computer is set to sleep or turn off power. Maybe somebody else shut it down.

shutting off completely to my knowledge... Noone turned it off and its downstairs so it wasn't me. Other then that now it turns on and no screen comes up... What thehell is going on??? ima start a new thread to grab attention because it wont start up..

does it even power on?

then i opened it and i checked to see if the atx 8 pin molar thingy was in tight and it was and there was a thing handing on the HD4890 i took it off although idoubt thats the problem.... and windows update asked me to download Some malicious removal tool...

what was hanging from your card, but make sure the card is fully seated especially towards the back of the motherboard, this is where I had to apply just a little more pressure to get mine in.

you are using 2 6 pins PCI power cords for your card, right?

don't download a thing its all junk, just run your games I never had any of that stuff and I never got one single virus or crash. Uninstall everything and anything you don't need and set your browser to block all pop ups all the time. Thats it.

how are your fans set in your card, and how were they set when you left it on all night? And don't leave it on all night again.

if it was me I would keep trying to start it and see if it kicks back on, if all the wires are tight. Just don't leave it unattended.

keep trying, until nothing at all happens. Then test your power supply as the other poster said.

re-seat your video card and make sure othe components are properly seated.

It's most likely your psu is fked, and its affected other parts of ur build, with my current sig rig, a thermaltake 1000w toughpower died after 2 days, and it fried my motherboard, cpu, and ram.

I have reset the video card. I also got some temps i think it might be the cpu not sure. The fan is working though cuz it was moving. I have a Corsair 750TX., how do i know if thats the problem? I turned on my computer on came the motherboard lights but no video card lights ( which was the normal way for me) so it looked fine i got temps and shut it off cuz i was scared of doing something. I took off the fan and check to see if the cpu was fried but it didn't look like it was nor smelled so im guessing its fine, http://img4.imageshack.us/gal.php?g=p1010309m.jpg RedxSniper

is that your cpu running at 60c idle? shouldn't be that high. mine is max 33c.

thats way too high if its 60c and its only been on a minute. if I was you I would try removing the cpu cooler and reinstalling the cpu cooler again. maybe it isn't on right. but thats way too high temperature seems to me. mine only reaches 33c after gaming for hours, if it gets that high.

I don't want t touch the cpu till i know that the psu isn't messed up. I got a multimeter, how do i use it?RedxSniper

I don't know, but it can't be too difficult, look it up at google.

Couldn't find a guide or anything. CAN someone please tell em what i should check and how? it's been 2 days and my parents are freaking out.... I mean they just spent 1000$ and they don't know much about computers if anything, so they are freaking out...

Try making sure the 20 + 4 pin on your motherboard is in properly. Try checking all of your cables.

I already did ll that. Im going to state my whole story as it might help out. Because i haven't gotten an answer yet only questions.

I was going to say, it's probably the heatsink fan not being installed properly. Remember to use ArctiClean when reseating the heatsink fan on to the processor - and you can get new pushpins from anywhere, really. They're pretty cheap.

Are they plastic pushpins? 'Cause if so, they'll probably snap if you try to remove them. If you're going for a new heatsink fan, I'd swear by the Titan Fenrir - that thing is ridiculous! As for the PSU, I wouldn't recommend opening it up - test it in another computer (if you have one), or RMA it and let some techies have a look for you. As far as I can see though, your temp problems look like they're coming from your heatsink fan not being installed correctly, or there not being a nice spread of Arctic Silver 5 between the processor and the heatsink fan.

Um well everything is working now, and they locked my "I FIXED ..." w.e thread, so ill tell you if it shuts off tomorrow. Later.RedxSniper

They probably locked it cause you used all capitals in your subject. They seem to get pretty upset at that. At least that is the only reason I see. I'm glad you got it fixed, continued luck.
