U said that your windows logo being slightly gray as it booted into windows, as far as i know this is a hardware failure, rma it...
Actually i have had a look at my hardware and i noticed my PSU is a LC-B400ATX im wondering if this might be the problem, iv read some of the reviews and it claims to produce 400w, im wondering if this is actually fact and would this be enough
My PC's specs are
3.4 Quad Phenom 2,
4GB of Ram
Could this be a problem for the PSU?
