I have changed my CMOS battery.Reset my BIOS.Even updated my BIOS with the latest ROM file.Problem persists. Here are my BIOS details: Model: P5Q-E Version:2101 Chipset:Eaglelake BIOS type:AMI BIOS Size:2048K Could it be a HDD problem?Could it be a problem with BIOS itself?Could it be a heat issue? Please suggest as I've lost all sleep and peace of mind. My SMPS is brand new. My config: C2D E7300 @2.66GHz| ASUS P5Q-E | Palit Radeon HD4870 1GB DDR5 | Corsair 800Mhz 2X2GB 5-5-5-18 | Seagate 500GB 7200.11 |Corsair TX 650W PSU
Guys the problem,I think ,has been solved!For the past few days,it seems that one corner was my Mobo had been grounded to the metal chassis,due to the nut coming loose..This led to voltage fluctuations and subsequent booting problems.Now the machine boots fine with a single beep everytime. My question is:Is there a possibility that my Mobo,specially the condensers & capacitors situated near the grounded portion,has already been damaged to some extent?Is there any way to know if my Mobo is perfectly all right?
