Even ONE bulged cap on the board can cause the issue - and you most likely have either 4 or 6, depending on the board design.. IF you can find a board that uses the same chipset the hard drive will plug on and run the system just fine on the new board - otherwise you will need to do some re-installing of the OS and drivers.
More likely you will also need to replace the CPU and RAM because you won't be able to locate a compatible board. ASUS uses a lot of solid caps now - which are supposed to be better than the old electrolitics
- but even the ASUS P5QPL-AM board I installed on a customer's system the other week had 6 electrolytics in the power section - where they usually blow - and the solid caps are touted as 5000 hr in the voltage regulator module (I assume at 105C - the temp rating of the caps)
Don't know about you, but 208.33 days doesn't sound like long life to me.
If they run at 65 degrees instead of 105, the lifespan should be closer to 50,000 hours - which is a bit over 5.5 years. - which is respectable but not exemplary life.
