hd spins up and a steady red light is shown ontop next to the green power button
processor fan dosnt start
dosnt respond to anything
1 Did you unplug the PC prior to opening it, and turn off the switch on the back?
2 Did you wear a wrist strap or ground yourself to bare metal on the case before you touched it each time?
3 Did you remove the motherboard from the case or work with it inside?
4 Did you put new thermal paste on the bottom of the processor before hooking it back up?
5 Did you make sure the heat sink is firmly fastened to the processor prior to turning it on?
6 Did you remember to plug in the processor fan to the motherboard?
7 Did you make sure all lines and cables from the hard drive and CD/DVD are firmly plugged in to the motherboard prior to booting?
I see where the hard drive boots up. But is the cable hooked up properly too?
What kind of processor, motherboard, and operating system do you have?
Numbers 4,5,and6 are pretty much fatal if not done or done properly. It only takes turning on a CPU once with no fan or properly installed heatsink to fry it.
If you've done all this, please forgive the questions, but you didn't say and I don't know what your level of experience in working on computers is.
If any of those items are not done, you need to do them. If you need directions write back.
Once done, then you need to clear the CMOS by moving the jumper on the RTC for say a half minute, then putting it back. Are you familiar with that? There are 3 pins, and the jumper will be on 2 of them. Move it the the uncovered one and the one adjacent to it. After 30 seconds or so, put it back on.
After that, there are a few differences of opinion on how to proceed. But I would put everything back except the side cover. Plug it in. Turn on the switch in the back. After a few seconds you should see a light on the back side or thereabouts come on. This tells you the motherboard is powered.
Turn the computer on, tapping F3 constantly with your finger to enter set up. Clearing the CMOS wipes out all your preferences. If you are lucky, and it boots you into set up, look at the top where it says "load Default settings". Press that and the save your changes and exit.
If the Gods are with you it will boot on in to Windows, if that is what you are using.
BUT. You must clean off the old thermal paste from the bottom of both the cpu and the heat sink. You can use rubbing alcohol and cotton (my ears are burning already). Apply a new thin layer with like a busness card, so it is evenly spread and very thin. Be careful when placing the heatsink back on it. Hook the back side first and then (I use needle nose pliars or a dull wooden pencil) push the other side down until it is hooked well onto the platform.
If this doesn't work, or you need help, please write back.
