Recently bought and built a new PC. Here's the specs:
Windows Ultimate x64
Asus P5Q Pro
Corsair DDR2-800 4GB (2x2GB)
Palit HD 4850
I've had it a week and it's been working just fine really. I tried changing some settings in BIOS (the multiplier was stuck at 6 instead of 9.5), etc. and I've run many Prime95 tests and it's going well. Even played some Warhammer Online and it's great! However, last night I attempted a minor OC. The ONLY thing I did was increase the FSB from 333Mhz to 350MHz. Everything else was left on Auto. It booted up and was doing just fine. I ran a Prime95 test and no issues. I realized though that the memory was running at ~417 frequency so I forgot to change that to stay at the stock 400. I was tired so I just did start > shut down in Windows and went to bed. But then...
This morning tried to turn it on and the only thing that happens is that the fans and lights all kick on inside the PC but nothing else - no monitor, no mouse, no keyboard. I'm new to building PCs and I'm not hearing any "beep" to indicate passing the POST. I tried restarting, unplugging power, etc. and still nothing. I then tried to clear the RTC RAM on the board and removed the battery and alas, no luck.
I don't even know where to begin. I only have one monitor so I can't see if anything is actually happening in the background. Any help/advice you can give me I would greatly appreciate it.
