Please log in for more thread options overclockers.com (London....can't get these in the U.S.), and a Athlon 64 X2 4600+ CPU from Newegg. The reviews of the mobo were good, and I had a high-end AGP video that I wanted to keep using....this mobo is one of the rare ones that have the old AGP video slot. I got 2 gb of Corsair XMS DDR2 (four sticks) installed. Well, when turned on, the CPU fan and two other fans run, but absolutely nothing else happens. THere is no HDD activity heard at all, no video, and although the case speaker is hooked up, no beep codes. I disconnected reset sw in case it was stuck closed. Checked CMOS reset jumper, it is not in wrong pos. Checked battery, it is 3volts. My AGP card and the 550W P/S are proven good, they worked fine in my older Athlon XP PC. The boot HDD is known good. Fans come on when the power button is pushed. If button is pushed again and held for a few seconds, the fans go off (power supply does shut down). I am thinking that for a PC to be this dead (never built one this dead before), either the mobo or the CPU is dead. Problem is, I don't have a second one of either to sub in. Is there anything else i can do to maybe determine whether it's the mobo or CPU? I am really up the creek here, as another mobo has to come from England (don't know if I can even find the receipt now...I bought it months ago, and it sat unused until today). Guess I will have to order another CPU from Newegg. What are the odds of Newegg shipping me a DOA Athlon 64 proc? Advice? | |||||||||||||

The AGP card has slits cut in it, to line up with the keys. Basically, if the card mechanically fits in the motherboard connector, the voltage is OK. (Exceptions are cards like SIS305, but I hope they're all in the landfill by now.) http://www.playtool.com/pages/agpcompat/agp.html I would check and make sure the main power cable, and the 2x2 ATX12V power cables are connected. Try using just one stick of RAM and move it around. Remove the video card and try to get a missing video card beep. Remove the RAM completely, and try and get a missing RAM beep pattern from the computer case speaker. Once you are down to just CPU and motherboard, it isn't possible to fault isolate further than that. From an odds point of view, the motherboard is more likely to be defective than the CPU. As long as the CPU has been handled with antistatic precautions (i.e. not a CPU you got from Ebay, that was rolling around inside a cardboard mailer, with styrofoam peanuts as its only company), the CPU is likely to be OK. If the BIOS is not a recent enough version, to handle the stepping of processor, that can prevent it from completing POST. It doesn't even have to beep in that case. About the only other diagnostic aid, is a PCI POST card (the one with the two seven-segment LED displays), and if you get a code other than 0xFF or 0x00 on it in hexidecimal, it means the CPU is alive and doing something. If a PCI POST card shows BIOS activity is present, then it could just be a too-old version of BIOS. If you try the motherboard, outside the computer case and sitting on your table, that will eliminate the standoff shorting to something on the bottom of the board. On my last two builds, I assembled the computer completely on a table first, booting into Windows as the final test step, before moving the components into the computer case. You need a good sized table to do that. Paul | |||||||||||||

It's very unlikely the cpu or the mobo is bad unless you put the cpu cooler on wrong and burned out the cpu... and you would have smelled it! First off, try the system with a very minimum of components...viz: Disconnect the HD, floppy and all cards but the video of course. also double check all your connections. Reset the bios of necessary. If it's still no-go...even though your video card is known good...it may not be compatable with your mobo...read all the specs well -- Posted via a free Usenet account from http://www.teranews.com | |||||||||||||

NO, the CPU has definitely not fried...no fried smell. I read the fine print in manual about the Asrocks' AGP bus...it only supports 1.5v AGP cards. Use of a 3.3 volt card may cause permanent damage. Maybe that is why it won't boot up? The AGP card I installed is a Radeon X800XT. I have searched google for specs on this card... none of the many sites I checked mention the voltage spec, they all just say "8x". Even the cards', manual also does not state voltage. However, I was using it OK in my old Athlon XP/ Asus a7n8x-x mobo, and I did find that the AGP voltage spec for the -dlx version is 1.5 volts....and I would expect that the -X version is the same. can't believe it is so hard to find AGP voltage specs for video cards!!!! Need to know for sure what it is. Anyway would this incompatibility shut the whole system down? Geronimo >
