So, a while back my pc had been randomly restarting. One day it never would turn back on. I had to RMA my motherboard and pwr supply just for the sake of knowing. I got them back recently and it kept happening! This time more frequent. It is like 2-20 minutes. It has never really lasted longer than that without rebooting. It does this infrequently. I did a reformat of my c drive and reinstalled windows 7. Updated bios, virus scan, and all drivers. No avail, still happens. No memtest yet, but how is this still happening?
PC Temps hover around 36c. The hard drives are in a ide setup mode for now. I thought overheating was the problem, but I had a fan set up with the case open to see and it still has random resets.
One problem I think is the network card. Realtek onboard lan may be causing instability problems. The pc restarts mostly when I use the internet. before the drivers were installed I couldn't plug in the ethernet without the pc restarting. Plugging in usb devices sometimes triggers a restart to. This motherboard has been doing this since I had my old one before the RMA. Must be driver related? No memory dumps though and the restart on system failure is unchecked. wat do?
I could watch tv shows for a long time and I don't think it ever reset while doing so. I did a memtest for 7 hours and it seemed fine. Never completed it though.
I have tried using 1 stick of memory in each of my four slots. It also has been cleaned. well. I had once heard about my mobo not being grounded well. but I have taken it out a bunch before and reset the mobo. Sometimes when this happened (before RMA), it would not turn back on. Often I had to take everything apart and put it back together before it worked again.
