I'm having an issue with a computer I've recently been upgrading. I've started upgrading all of the obsolete 4 year old parts, so I've replaced the PSU, CPU, RAM, GPU and Mobo; however, when attempting to start the computer it powers up for a few moments and then shuts down. I've scanned the typical 'what do do if..' threads, followed their advice and still been plagued by the issue. I've tracked the problem to the CPU, by uninstalling everything except for Mobo, PSU, CPU and RAM. When the power button is pressed, the computer starts for a few seconds before shutting down. The CPU fan gives a few weak lurches before stopping. A few seconds later, the computer turns itself on, and then shuts down again. I'm fairly certain it's the CPU because the case fans and GPU fan all start spinning normally when plugged in.
For reference, my specs are as follows:
GIGABYTE GA-Z77MX-D3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply
Patriot Viper 3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model PV38G160C9K
It's worth noting that this has been a test run on a new PC- I haven't connected an HDD yet. I know that I can't get past BIOS without a hard drive, but right now I can't even get TO BIOS because the computer shuts itself down.
I forgot to mention that I had this issue with my previous PSU as well, and I am still having the same problem with the new one. So I don't think the PSU is to blame, since my previous PSU ran my previous computer just fine.
My problem here is that the computer is literally only on for one, maybe two seconds. I can't do anything, and the motherboard has never successfully booted so I haven't been able to access BIOS. It's not even long enough for the motherboard speaker to beep.
yeah have you tested your psu? i know it sounds weird but test it because that sounds exactly like if you had a bad psu... now if it passes it easily could also be the mobo... i think if the psu passes the test(in my previous post) then you will want to rma your mobo
ok sounds like a plan, also be sure to check the ram because it could also be that if you have any other ram to test put that in, if not then get that rma'd when you get your mobo rma'd(if you decide to)
Hold on a second. I checked my Mobo's website. The RAM it came bundled with (combo sale on Newegg) doesn't fall under the supported RAM in the list. There's other Patriot RAM there, but not the specific model that's in my machine. Would Newegg really send me RAM with a motherboard that doesn't go together? :|
seems that way... so then i recommend calling newegg and gettinga refund on the ram, what i dont understand is the ram is 240pin and is ddr3 how is that not compatible?
well i mean i see what you mean its not on the support list but the other patriot ram is so im not sure if the ram is just not faulty
This weekend I'm going to disassemble all the parts, ensure the mobo is seated correctly on the standoffs, and if it still doesn't work I'll RMA it. I just don't want to keep using this shoddy old Pentium 4 PC.. *shudder*
