Question Fans turn off and on every few seconds but pc will not boot

[BigMoneyJesus]

So I just bought a game my PC crashed and I thought nothing of it. I try to restart it and the fans of every thing spin and stop every few seconds like it’s getting power surges. I recently SLI’d 2 GTX 770s but I have been running it for a week at this point and my PSU is beefy running at 850 wats capacity. My pc is my main form of entertainment so I’m desperate for help. It doesn’t even get to bios so the only “symptoms” I have is the fans turning on and off intermittently.

What is full system spec including PSU make and model?

recently SLI’d 2 GTX 770s but I have been running it for a week at this point and my PSU is beefy running at 850 wats capacity.

Which PSU model is that ? Also, you need to provide more system details. Kindly provide FULL PC specs. How OLD is your GPU as well as the PSU ? Do the cards work fine without SLI, in a single GPU mode ?

-1. "Complete" system specs should ALWAYS be accompanied with any driver, hardware, or performance question. Do not post DXDiag reports as they contain a TON of useless information. Posting a DxDiag in place of a System Spec List tends to ward off potential members from helping you.

Please supply the following system details/information:

(Complete System Specs)
-CPU make and model# (clock speed/voltage, type of cooler, and "Core" temperature @ idle and load)
-Motherboard make & model# (include Bios version if graphics card is not recognized or you are having stability issues)
-RAM (amount, clock speed, model#/link of kit, configuration)
-Graphics card(s) make and model# (clock speed, voltage if modified, Driver version and GPU temp both @ idle and load)
-Power supply make,model#, "AND" age (note if using 110V or 220V A/C input)
-HDD/SSD configuration (ie: Raid setup/ back up/ OS drive/etc..)
-Case/Chasis make,model# (fan make, model#, and configuration if having thermal issues)
-Operating System (If using Windows note Framework and service pack version)
-Monitor make, model#, and resolution (If model# is unknown list resolution and refresh rate)

*If the unit is a "laptop" or "All-in-one" system you must note the make and model# of the unit. Be sure you are ALWAYS using the OEM/manufacturer's Driver updates for the unit.

*If "Crashing":
-Note the nature of the "crash" in detail, as there are several definitions for the word "crash".

*If "performance" related issue:
-Note the "exact" point in which the performance reduction occurred (ie: After Windows update, After Bios update, After Driver update, After thermal system shutdown, After Hardware change/upgrade etc...)

*For diagnostic purposes please disable the following:
-Any/all Antivirus/ Anti-malware software
-Any/all OSD monitoring software
-ALL overclocks outside of factory spec .
