PC won't turn on

I need some help before I throw my PC across the room! My computer won't turn on! There is a little green LED on the motherboard that I can see is lit, but when I try to turn it on...nothing.

Right now I can't get to the box that has all the computer info in it (mobo, memory, power supply type) but if I need to give that info out I can tomorrow. I was just surfing on my other PC and wanted to ask. Has anybody heard of this problem? I'm pretty sure there's power to the system, and occasionally I can get it to turn on, just not regularly. Any help would be appreciated, since then I can quit reading about games and actually play them!

When you press the power button what actually happens? Do any fans spin, or does you HDD make any noise?

Sorry for bumping an older post, but I still need help with my PC. It has taken me awhile to get back to the problem, but here is what is going on now. I opened up my case and now it will turn on regularly (crossing fingers) but now I can't get my hard drives to work. I bought a new one (it is the same type as what I had) and installed it but when I boot up I don't get anything. Everything is hooked up but the monitor doesn't even turn on. One time I got the BIOS screen (I was booting from a Windows XP CD) but then the screen went blank again. I checked all the connections and they seem pretty secure, but I am getting really frustrated!

Should I take the HD out of the case, still connected, and see if I can feel the platters spinning? Maybe the drive isn't getting powered? GRRR!

Once again thank you for your help/advice if you can give me some. Have a great day!

Thank you, but that didn't work either. I tried taking the battery out too but still no go. There were two jumpers near the battery so I tried moving both and it didn't change anything. Don't know if you have any other ideas, but thank you for the help you've given so far.

my too have the same experience.. i'd overclock my Q6600, and i try overclock the ram too at 1066. then i save the settings and quit. then the bad thing happened... computer wont on... so i unplug the main wire that connects to the psu without knowing the switch is still on,then i re plug it in back to the psu. then i heard some weird noise coming out from the cpu. the i try on my pc again,it wont work... the green led is on,but all the fan is not working...even the hardisk too... is my mobo fried?

That sounds worse than my problem. All my fans are working and the mobo LED is on also. I think I'm going to try and borrow a video card from a friend and see if switching them out does anything. Of course with electronics, you know it's one little thing that is causing the whole system to be unusable. The hard part is finding that one little thing!Dawgs42

ok, just to make sure does the board 'post'? Ie does the bios beep on startup and go through its startup cycle? If thats so then I would say its almost positively the video card.

Thanks for all the help and advice, it's really appreciated. Only once has the computer booted to the BIOS screen. I thought all was good but then the screen went blank again and the light on the monitor started blinking again (I didn't hit the power button, the screen just went blank) as if it wasn't getting a signal. I took the HD (it wasn't screwed into its holder in the case) and bolted it down, not unplugging anything. It doesn't beep or anything either, just fan noise. It's a new HD so I have my Windows install disk (full version) in the drive for when/if it works. I'm at work right now, if it helps I can post the specs when I get home. I am going to try and borrow a friends PCI-Express video card tomorrow and try switching it out with mine. I'll probably post again after I do that, sometime Sunday afternoon, unless someone else offers another idea.

Once again, thank you everyone for the help you've offered. I've never really asked for help this way, and I appreciate not being flamed or ridiculed. I promise I'm not an invalid! Have a great day!

Could be your PSU playing up.

Once again, sorry for bumping an older post, but I wanted to say thank you for everyone who helped me out. Thank you! I eventually switched out my video card and now everything (almost everything) seems to be good. A friend gave me an ATI X850 XT video card for free. I know it's not the next best thing, but it's still pretty good, I think! Hope everyone is having a great day!
