The system is in my system specs under the 'Black Panther' name. Lately it's been running at stock, nothing overclocked. Tbh it seems the problems started when I removed the overclock Notwithstanding the clear title, the problem is anything but consistent! Here's what this pc does: - It will start up fine and run fine forever until switched off; or - It will start up fine, then after a couple of hours the picture on the monitor would freeze, requiring a hard-boot; or - It will start up fine, then after a couple of hours the monitor would go on standby requiring a hard boot; or - It will refuse to POST saying 'overclocking failed' press F1 for bios or F2 to load system default (the system is not overclocked); or - It will start up and appear to be running fine, only to find no sound; or - It will refuse to POST giving the beeps mentioned in the title; or - It will refuse to POST giving no beeps at all; or - It will POST but before loading windows the monitor would switch between black and a slightly lighter shade of black (seeming like the graphic driver can't load?) Once it was running fine then I found this BSOD: Spoiler Anyway, it does all the above with varying degrees of frequencies. Before I started typing this post it had started beeping again, but I wouldn't be surprised if I power it on again and it boots and runs fine as if nothing ever happened. Before these problems started, nothing had been installed or changed on the pc - no drivers, no programs, nothing except the mandatory Win 7 updates. The only thing I did was remove the overclock since I passed the pc on to my daughter and she rarely uses it for gaming. But removing overclock is supposed to solve problems not create them! Anyway, it's still running same drivers, same programs as before. I ran a virus scanner and malwarebytes, ran ccleaner... All my searches on the P5B's beep codes point out at graphic card failure (I hope it's not!!) What are your opinions? Any clue from the screenshot above?
