my motherboard is via and processor is p4 1.7 GHz but the problem is whern i m installing the processor the motherboard take a bow shape and the power supply dose not reach to the processorbut when u relese the heatsink every thing just do fine. so what's the solution on this problem
U shud install the cpu before installing the mobo to the case. Else u will bend the mobo like you did. If you don't want to take out the mobo, then check if you have screwed in all the srews that hold the motherboard to the case.
And if u are reinstalling the heatsink on the processor, apply some thermal paste or thermal pad before doing so.
