Hey, Folks, I'm on a Gateway P7805u FX with no overclocking, extra ram or anything else. Until recently, it was running beautifully, and until night before last, was only mildly annoying. That is to say, Internet Explorer would periodically stop working for no apparent reason, requiring me to close it and start it back up. Over the last few weeks, however, the computer has often run slow enough that I did several (and several kinds of) virus scans to make sure there wasn't something hijacking the system. They've all come up clean, whether they've been online scans, scans from within the system (Nod 32 and Malwarebytes), or through a bootable disc (both Kaspersky and BitDefender). Night before last, things got completely out of hand: "Windows Explorer has quit working" seemed to be popping up 10 minutes. At that time, I did a complete strip and reinstall of the OS (W7 x64). Things froze up right from the beginning, but it got really bad when I updated Java, so I uninstalled it. I also updated NVidia's latest driver, but don't know if it's had a negative effect or not. Unfortunately, that hasn't helped. Not only is Windows Explorer prone to quit suddenly, but now it sometimes hangs when I try to open folders. The window opens, but it goes into a "search state", and doesn't show me the files in the folder unless I log off then log back on. That is, if it doesn't freeze to the point where I have to do the five-second sledgehammer to turn off the computer. Out of desperation, and because the fan seems to me to be running medium high during most of this, I installed GPU-Z and SpeedFan, following the advice of a thread on this forum. At this very moment, with the browser on and nothing else, the GPU temperature is ranging between 48-53C; the CPU numbers are as follows: GPU: 49C HD0: (the one that's running) 53C HD1: 51C Temp1: 61C Temp2: 60C Core 0:53C Core 1: 53C These temperatures drop or rise a degree or so every few seconds, but as I freely admit to having no clue of what they signify, I don't know if that’s good or bad. Any suggestions on this would be greatly appreciated; I've googled "Windows Explorer has stopped working and tried several of the suggestions. I even turned off most of the shell extensions using a program called Autorun, since it initially seemed to happen when I messed with the right-click context menus, but it hasn't helped. So, is something mechanical at fault? Is this something I can remedy with... I can't imagine what? This is my work computer, so I really need some answers as soon as possible.
