Problems with paste

[Darkithanime]

i just recently put in a new fan and I've been getting blue screens and i fear i didn't use enough thermal paste. Could this be from not enough thermal paste and it overheating?


the computer also will now only turn on every other time i power it up. should i buy a new power-supply? could this also cause blue screens?

i just upgraded from the stock fan to a NZXT HAVIK-140

You may have put too much paste! Clean it off with some rubbing alcohol and reapply. If you need help, read this guide: http://www.tomshardware.com/forum/333968-28-thermal-paste-removal-installation-guide

The best way to see if you have used the proper amount of TIM is to use a temperature monitoring program like coretemp. If your temps are below 60C under load, you should be okay. Keep in mind that too much is also a bad thing. You can always reseat your heatsink if it is that much of a worry. Although high temps can cause thermal throttling and some hardware freezes, I would be more inclined to suspect the PSU.
The PSU is truely the lifeblood of your computer and voltage variations can easily cause BSOD's. It would also easily explain your every-other-time startup issues. If you have a quality PSU, I would see if you are still under warranty. If you do not, now would probably be a good time to invest in one. I cannot say for sure that is your problem but that is where I would start.

When looking to purchase a PSU, do not go strictly by brand - even quality brands like Seasonic, Superflower, Corsair, FSP come up with duds now and again. Check out the exact model's reviews from JonnyGuru, HardOCP and HardwareSecrets - those reviewers actually stress the units, tear them apart to see how they are made and the quality of the parts and build, fascinating reading. Or, look up that model PSU review by them and skip to the last page without reading the filler, either way, you shouldn't go wrong.

all right i reapplied the paste and for some time the computer just wouldnt start up so i disassembled the whole thing put it back together and then used a screwdriver on the power button pins to start it up and it worked great....


i think the problem was that i had the positive and negative ends switched around with the power switch

thanks for the help peoplez
