Just finished building my first desktop, but it reboots itself every five seconds before anything even shows up on the display. The case fans, the CPU cooler fan, and the GPU fans work, and the CD drive lights up and whirrs for a while, so they all receive power. What might be wrong?
Hmm that is interesting you can't even get into BIOS. Try pressing delete or whatever key you press to get into BIOS anyways just in case it is rebooting right when splash is about to hit. Maybe you can get into BIOS and change boot drives around.
But if you absolutely cannot get into BIOS try unplugging your hard drive(s) and CD drives and try booting then. Let me know if it changes!
Also, make sure all your connectors are tight and secure!!! Check and double check them!
Also! Make sure your heatsink is installed properly. Even if you check and it is, check again! The computer could be rebooting because of over heating. If you have left it in the reboot loop long and it is over heating, you may have damaged your processor
I hope that did not happen!
I removed and reinserted the CPU, the heatsink, the RAM and the GPU, as well as the front panel connections and USB connections. Unplugged the CD and hard drives. I also tried using a different plug. The capacitors on the mobo do not seem to be broken or leaking. The RAM is 1.5v
Do I need to add extra thermal paste on my CPU? It seemed the Intel heatsink already had some so I didn't think I needed to add more.
I also tried to boot without the video card, and did not notice a difference in the reboot duration or frequency, if that helps.
Here are the specs:
MB MSI H61M-P21 (B3)
VGA SAPPHIRE|100315L HD6850
PSU ANTEC|TP-550 550W
CPU INTEL|CORE I3 2120 3.3G 3M
MEM 8G|GSKILL F3-10666CL9S-8GBXL Ripjaws
HD 1T|WD 7K 32M SATA2 WD1001FALS
Ok well it may just be that you don't have a speaker. If you have friends or spare parts I would start swapping out parts that you know work. Very annoying, hope you get it fixed. I am going to be building my first build (all on my own) in a couple weeks.
Unplug all your case switch and LED wires, and use a flatblade screwdriver to short the power on pins (ref to your mb manual for the PWRSW pins) just to rule out a fault (it's unlikely but it happens), pref do this with as little connected as possible just to do a post test.
What I did was to restart it before it got a chance to reboot itself. Installed Win7 and all drivers, and now it refuses to connect to the uni internet because "Windows can't communicate with the device or resource (primary DNS server)." Both ethernet and a separate wireless adapter end up with the same problem.
I did. I installed the LAN driver that came with the CD of the motherboard. It actually finds the connection and says "X Residence Connection" (the name of my connection), but then says No Internet Access. I can connect my XBox to the internet using the same ethernet cable just fine.
check under network settings that two buttons are one for auto dns and id. the router is going to be the dns server. you can tell if the setting are right by logging into most routers. if the pc not setting the dns up right you wont be able to do the 192.168.1.1 to get the router log on screen to pop up.
