Hi guys
I have recently had trouble after about 30 mins of playing a game when it goea glitchy lag to the point it cant play and it as shut twice on its own. So having a far bit of knowledge of pc i build my own i began troubleshooting knowing it cant be my graphics card its brand new i done a memory test also memory swap out and no beeps tested power supply fine then i downloaded the intel dianostic tool to test cpu which it did and it had error message saying change thermal paste or to words similar to that.
So i did cleaned the cpu and thw cooler which is a corsair h75 liquid cooler cleaned it all with isopropenol re applied thermal paste from corsair pea size and let the heatsink spread it out like i have done loads of time before .
Bit now it wont boot i get no error beeps or nothing all fans are running mother board working normaly and the carda are all powered ligjts on case but no boot on monitor .
Ive removed cpu incase i had put to much thermal paste cleaned it and redone it also checked all pins and the cpu back to make sure all clean still nothing .
The only thing i havent done is do a cmos wipe .
Please any help would be great
Steve
