Khenglish 1155 Posted January 18, 2015 Did you turn the CPU screw to lock it in? Quote Share this post Link to post Share on other sites
kothletino 12 Posted January 20, 2015 He has already found a solution. The problem was the RAM. Quote Share this post Link to post Share on other sites
soundslikerust 10 Posted January 20, 2015 In case someone have similar problems and found this1. check voltage on your power adapter - it should be stable i.e. if you have 19,5v it should be stable within 19,45v-19,55v. If it goes wild like 17v 18v this is it2. remove battery, power adapter plug, swap ram, run it with first than only with second ram etc. Remember to turn it off and remove battery when inserting/removing anything 3. listen to sound signals before post (thats obvious, check the net about those signals meaning)4. sometimes there's some cold soldering in the power plug on the motherboard and it needs to be resoldered in older notebooks (it's not exactly running fans like reazerix wrote - its just sometimes not starting but its very often found on older machinesif i remember anything more i'll edit this, good luck Quote Share this post Link to post Share on other sites
