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?
