No BIOS or video with P5LD2 Greetings. I have just built a new PC (see specs bellow) and I am receiving neither a BIOS beep nor video signal. MB: ASUSTeK P5LD2 CPU: Intel-PentiumD (LGA775) 820 2.80GHz BOX(EM64T) RAM: 240PIN DDR DDR2 PC4300-1GB(DDR533) HYNIX original (two sticks for a total of 2GB) VIDEO: HIS HX70PRQ128-3TOEN IceQII (ATI x700Pro 128MG) HD: Hitachi/IBM HDT722525DLA380 SATA 250GB OD: LG GSA-4167BB Multi DVD drive C/PS: Antec SONATA II with 450W Smart Power 2.0 PS MISC: MITSUMI FA405T(B) (3.5 inch card reader) Here is what I have done: - assembled the system both in and out of the case, piece by piece; - verified both the 4-pin ATX 12V and the EATXPWR 24-pin power connectors are firmly attached; - confirmed jumpers are set to factory defaults; - doubled checked that the RAM modules are inserted in the appropriate DIMM_A1 and DIMM_B1 slots -- though, I have also tried every slot with one module and all two-module combinations; - checked that the HD is connected to the SATA1 port; - cleared the RTC RAM; and, - cleaned video card and RAM connectors with rubbing alcohol. Here is what I have observed: During both in- and out-of-case assemblies I was able to power up the system (CPU fan, case fan, video card fan, and motherboard) but received neither BIOS beep nor video signal. Only silence. After trying multiple RAM configurations, resetting the RTC RAM, and cleaning components with rubbing alcohol, I was greeted with the same familiar silence. While conducting a piece by piece assembly, the motherboard finally spoke: three beeps -- what sounded like a long beep followed by two shorter beeps -- after powering up the motherboard and CPU without RAM. (I think it is important to point out here that this beep pattern does not appear to correspond to anything in the user's manual). I then powered the motherboard, CPU, and RAM. This time I heard 2 or 3 fast, short beeps. The third assembly included the motherboard, CPU, RAM, and video card. Silence. No beeps. I removed the video card and connected the HD. Those 2 or 3 fast, short beeps returned. I added the DVD drive, card reader, and case light in succession and each time the beeps sounded off. With the system 99 percent complete, I returned the video card to its PCI express slot and upon powering the system an all too familiar silence returned. Consequently, I noticed that when the video card is removed I am able to shut the system down normally by depressing the case power switch but when the card is installed I am unable to do so. I have to reach behind the case and power down the system via the power supply's power switch. Now, I have corresponded with ASUS' technical support staff and as of our last e-mail volley they are leaning towards either a defective motherboard or CPU. They did recommend I try another video card but unfortunately my spare systems are a vintage AMD K7 600 and an Anthlon 1.1GHz, neither compatible with this more 'modern' technology. Is it possible that the video card is deficient and the motherboard and CPU are viable? I am not looking forward to building a whole new system just to troubleshoot this one. Any insights you could offer would be most appreciated. Thank you for the assistance.
