Hi all, Long time it has been! I have a P5Q Deluxe mobo, old I know but it is still good for me. The trouble started when I shifted my PC while it was on and I heard the kettle plug by the PC's PSU arcing. And to think that this is from the power lead that came with the PSU! The plug does not really fit tightly so it arced a bit, since then I cannot change any values in my BIOS except loading .my OC profile. Now I do apologise if someone else has posted this exact fault although I doubt it, please let me know what to do, I dont want to lose my OC profiles as one of them is for standard speed non-overclocked, the other is for OC'ing my Q6600 to 3Ghz.. I have two BIOS chips, if I swop them around will this sort out the problem and will I lose my OC'ing profiles as I have long forgotten what the values must be. The mobo also seems to have a flat cmos battery as the mobo doesnt keep the time and date (not that I can change it). I can move around the BIOS no problem but once I try and change a value it hangs... Your help will be appreciated.
