hi, please help, i recently cleaned pc fans i removed motherboard from case to do this leaving cpu cooler attached. now the problem is when i put it back together it wont post beep, no bios just all fans spin up. yes ive checked connectors 5 times over, retested bios, removed ram and tried different scenarios like no ram, 1 stick 2 sticks different sockets and nothing. ive tried psu and gpu in other pc and all is well. so any suggestions please.
hi everyone and thanks for the replys. ok its out of the case and on the original box. i disconected everything and except the the cpu and heatsink (no fan). i went from there 1 stick off ram in defferent slots then 2 sticks, gpu and still nothing. nothing from the speaker either. ive went over all the connections then checked them again. could it be a dead motherboard or cpu? if ram was dead id surely get some beeps?
agian thanks for replys guys really appreciated.
Removing the fan from the heatsink might have made the connection of the CPU poor originally. Disturbing the thermal paste. Running it out of the case without a fan at all might have fried the CPU. It takes seconds to fry a cpu without cooling. Most modern motherboards use the case as neutral but the original machine screws must be used. Size of the heads of the screws are important as well as not over tightening.
i think ive disturbed something. at first i didnt power it on with no cpu fan attached but if i did im sure the Xigmatek Aegir with no fan would control the heat for a few seconds. when i removed it from case it was only slightly out so i could get at everything easier. i think its time to get it in the local pc shop because im getting withdrawal symptoms haha. if they find the problem ill post it on here and thanks guys.
Whilst motherboard is out of case try using a small screwdriver to short out power switch pins. The power switch on most computers is a "push to make" switch that does not stay connected once released.
If computer works, use reset switch as temporary alternative.
ok so ive just tried the screwdriver thing and its the same, just fans come on and no life no beeps and nothing on the display just fans. when i leave it on for a while the heat pipes on cpu cooler are still cold so could that mean something ?
ive used 2 different speakers (one from another case). the main power connection is 24 pin and the cpu power is pluged in also (ive also forget this in the past).its going in the lcal c shop in morning so hopfully they will find problem. i really appreciate the help.
