Hi. Been browsing a few topics on advice, but mine seems to be a combo of a few! I'm running a Shuttle case (not too sure on spec at the moment, as it's about 3 years old). Lately it's been acting weird, showing power supply problems. (I think). What will happen is, if you switch it on NOTHING happens. No fans, monitor, CPU, no LED's nothing. Don't touch anything & just leave it, then after about 10 secs to a minute even, it comes to life & switches on. After a few weeks of doing that, increasingly the following happens: you switch it on, nothing happens as before, & when it wakes itself up after a while, the fans run, we have LED's on the case, but no monitor. In this state I must add it is impossible to even restart or switch it off. I had no choice but to pull the plug from the wall! After this behaviour, when it starts, it's then in safe mode obviously, & you can then restart as per usual & then it works fine. In the last 2 days, even after the safe mode restart, I have no monitor again, & have to repeat the whole power interrupt to get anything to work. Lately, it's been happening more frequently, but I must add that a lot of the time, it's fine.. You press the power switch, & it comes on immediately?? So can a motherboard/ power supply be intermittantly toasted? Should I call a priest..
