While fixing a Gateway LX 6810-01 desktop computer it cuts off every 15-minutes

While fixing a Gateway LX 6810-01 desktop computer it cuts off every 15-minutes. I ran system diagnostics and checked for virus issues. After resolving all virus/malware issues by reinstalling the (windows 7, 64-bit) operating system, seating the ram and changing the power supply, the computer continues to cut off after the computer’s case was reapplied.
Moreover, a quick inspection of the cpu and fan settings in the bios shows the computer is cutting off b/c its reaching in excess of 75-80 when the cover is attached. I placed a small fan on the cpu and watched the temperature go down to 70. But this room fan is only a temp fix to prevent the cpu from damage while I inspect the thermal paste, exchange the fan, and add another if necessary to bring the temp into normal specs. While in bios I was unable to adjust the fan settings. The MBO has a 3-pin and 4- pin for fans. The four pin is in use for the cpu fan. I ordered a 90mm, 12v 3-pin fan. I just want to know if I covered all bases? Any ideas?

gonna assume you've already cleaned the CPU cooler and it's free of dust atm. how dusty is the machine when you opened it? do you have a spare PSU sitting around to troubleshoot with? it's hard to say what can be causing the shut down on prebuilt machines since they don't exactly use high end components. I wouldn't spend any $ on the machine till you've got a good idea of what is causing the problem. from what you said, it can very well be a heat issue and depending on what kind of budget you have for repairing this, you may be better off migrating the machine into a new case with better airflow.

it seems like you aren't the only one having this problem


problem like this generally falls in 2 categories, not enough airflow, or really crappy PSU.
