Ok, so, the other day my computer was randomly shutting off. Opened the case, realized the cpu fan was dead, replaced. Then after the new fan was on, tried to turn on my computer, it came "on" but it didn't give the system beep and it didn't trigger my monitor and keyboard/mouse that the computer was on (none of them came on). So, thinking the bad fan crapped out the processor, we replaced the processor (even though it's intel and should be thermal protected). Still the same issue with coming "on" but not booting up or even system testing. Opened up the case, reseated the cpu fan, unhooked and rehooked all the connections to everything. IT WORKED! but only for one evening. Now this morning my computer is doing the same thing as before...no system beep, no trigger to the monitor...but the fans spin and so does the harddrive (from what i can tell/hear).
I'm frustrated and don't know what to think or do next. plz help.
