Self host physical access control software/database? Security.Due to the nature of our office (and politics), we don't have a wifi environment so the monitor would have to. Hey spiceworks world!Our office is moving into a new office building and we'd like to install a temperature/humidity monitor in the server room. Server room humidity monitor with alerts (ethernet, not wifi) Hardware.If it's the same, you have a bad motherboard. If you connect that to a minimum post system and don't get any beeps or boops or lights then you try another PSU. Generally, if you disconnect everything form the PSU, stick a paperclip from the green wire to any one of the black wires in the ATX connector and connect it to the wall and the fan spins the PSU is working (at least minimally). Well, I can tell you that in over 20 years of working with hardware I see a bad PSU every day, a bad motherboard a week, and I've never seen a single bad Intel CPU in my life that was not the direct result of obvious physical damage or an overclocking gone horribly awry. If anyone can let me know how to test power with the equipment I have at hand I would be very grateful. The issue may also be cooling, but I have some idea on how to test that. The PSU is a Corsair RM750x and the CPU is an i7 7700k in case this info is important. I have a feeling it may be power, how do I test that I'm getting power through the 8 pin CPU power cable? I don't have another PC here to test it on, but I do have a multimeter. I want to rule out all other possibilities before telling him to replace the CPU. My friend's previously mentioned PC is still having issues. Look for a very good friend using compatible parts which you can swap or try buying parts of e-bay. If non seen, you could try a solder reflow.ĥ. If you are then sure that the fault lies with the motherboard or CPU does, then visually check the motherboard for any possible problems. If that does not work then you are back to the dilemma of CPU or motherboard.Ĥ. If working it should go into the BIOS and you switch it off. Short Power on connections on the motherboard briefly with screwdriver and it should power up. And you need just a smear of some grease between heatsink and CPU. So add heatsink of some kind to CPU (it is not going to be on for long). (It is not unknown for case mountings to short out motherboard circuits). Check PSU for voltages on its own with DVM (Connect PS_On to ground to get it to power up.ģ. Replace CPU, carefully checking for orientation, bent pins, contacts, etc.Ģ. Strip PC down to parts and remove CPU from motherboard. If you have not done the following then do this before throwing money at random components.ġ. I do not know what diagnostic steps you have taken to come to the conclusion that it is either the motherboard or CPU. As I stated previously, "It is unusual for the CPU to die" and so if you are going to swap items as a way of getting it working then guess at the motherboard. I'm new to all this, and my current board doesn't have the additional 4 pin.Unfortunately, there is no sure way of testing whether the fault lays with the CPU or motherboard without a good working reference pair to swap around the parts. (If this is more suited for the PSU subforum, I can repost it there). If I don't plug anything into the 4, and I do some light overclocking, would it ruin the board? If I get from Corsair an additional CPU plug that's a 4+4 (and its marked CPU), and I can plug that into my PSU, I can plug one of the 4 into the CPU and not damage it right? While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it. This connector is used to supply additional 12V current to the motherboard. On PC part picker, I get: Note: The Asus ROG STRIX B550-F GAMING ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Corsair CXM 650 W 80+ Bronze Certified Semi-modular ATX Power Supply does not. I currently have my drives, a GTX 1080 (I plan to upgrade to a 3070 eventually), and plan to buy a Zen 3 CPU (Let's see what is shown tomorrow).
