CPU overheating, claims overclocking, blue screens, freezing.

I have a desktop that I built with the help of a friend about 2 years ago. Yesterday I tried to transfer it to a larger case without help. The computer will turn on and go to windows for a couple of seconds before freezing up or blue screening, sometimes it will change the resolution so it looks very strange, or only pick one monitor to show up on, sometimes two.

Sometimes it tells me that I am overclocking and need to reset to default bios settings, but I haven't set my desktop up for overclocking or changed any of the bios settings. The blue screens I have gotten are "IRQL_NOT_LESS_OR_EQUAL" and "MEMORY_MANAGEMENT". I have dusted out the case and components fully. The CPU reads usually at about 87-90 degrees celsius just sitting on the bios screen.

From things I've read online so far, most people seem to say it's probably just an issue with the fan. I have a small push pin fan that doesn't seem to be very effective, or even push in properly, no matter how hard I try, so I could believe this, but the issues with the monitors and the overclocking errors make me worry that it's something more. Also the fan worked before in the previous case, so I find it weird that it's not enough now.

Ideas?
 
If all you did was move all the same components to a different case and didn't change anything around, no hard drive swaps, hardware changes trying to run the same version of windows on another hard drive etc, then I'd suggest checking your components. Even if you didn't remove some things like ram, try pulling it out and dusting everything off with compressed air and reseating the ram.

If you remove the cpu cooler and put it back on, make sure you cleaned off all the old thermal paste and have new to put on (doesn't take much, pea sized is plenty). Make sure those pushpins are locked all the way in and didn't become damaged. Pull the graphics card out and reinstall it to make sure it's fully seated.

Try turning the power off, unplugging the power supply from the wall, removing the cmos battery (looks like a nickel sized coin cell on the motherboard) and give it a few minutes, then reinstall it. Then plug it back in and turn it on, see what the bios readings are for it then. (this will set bios back to factory default to make sure there are no funky settings causing the issue).

I'd also try just one monitor to start since you're having issues, no reason to add other complications into the mix until you know for sure it's booting up properly.

If that cpu cooler fails to lock in tight with the pushpins, look into getting a new cooler for it. The bios rarely reports wrong temps and 90 is awfully high especially if it's not overclocked. That would more than likely indicate a cooling problem. Hope some of this helps. Let us know how it goes and what hardware you're dealing with (cpu, motherboard etc) for suggestions on coolers and things and to help us understand better what you're working with.

Specs:

MSI Mainboard Z77MA-G45/Z75MA-G45
RAM Kingston HyperX Blu 2x 1600 MHz 8 GB
Nvidia GeForce GTX660TI PE series
intel core i5 processor
fan came with the CPU

I did just move everything over to a new case, no new hardware, but I worry because I did have to reconnect cables, and I am not sure if a mistake in that department could make something like this happen. I think the memory error might have occured before I reseated the memory, I think I later found that one of the sticks wasn't seated properly. At this point I have reseated both the memory and gpu over and over again, and I haven't seen that error since. I am going to order a new fan and try that one out, this one really wont clip in place, it probably needs the thermal paste reapplied as well.
 
If those plastic push pins got damaged at all or just with age don't hold tight and moving the board around wiggled it loose that would be the cause for your temperature issue. So long as the cables are plugged into the right places (almost hard not to since they're keyed to fit one way) and seated fully and everything else has been seated nice and snug, clearing the bios would set it back to factory defaults (safe, then go from there once stable). A new cooler will like fix your overheating problem since most aftermarket coolers snug themselves down with brackets and screws not just push pins. Definitely get some new paste (most coolers come with new paste if nothing else). Something like arctic silver 5 is pretty cheap and works well. If/when you clean off the old paste, wipe it off real good and use something like a qtip dampened with rubbing alcohol to clean off any residue from the old paste from the metal cpu plate.

Something like a cooler master hyper 212 evo, cryorig h5 universal, scythe kotetsu would all work well for stock or mild overclocking and are pretty affordable. If you plan to do bigger overclocks, you might want a bit better of a cooler, just depends on your budget.

So I got the fan today and installed it. Now the computer wont even boot up. The fans run for a couple seconds when I turn it on and then they keep going off and on until I shut the power off in the back. Also, I tried the bios reset the other day, taking out the cmos battery. The computer started working great, but then I rebooted because it was giving me weird internet issues, and then it started doing the same thing it's doing now, turning off and on.
