Hi. A couple months ago, my computer started having a range of issues. I will detail the issues and the steps I've taken to try to correct them and what is going on now. It all seems related to me, though may not necessarily be.
First off, here are my quick specs:
Intel i7 2600
Nvidia Gforce 560 GTX 2Gig
(External Hardware: LF Flatron Monitor, Razer Naga 2012 mouse, Logitech flat keyboard, Logitech headset)
Windows 7 64-bit Home Premium
The most recent Mozilla Firefox is my default browser
Around October, I start having multiple issues crop up all at once (funny enough, almost 2 years to the date I bought the system...):
-Frequent Kernel-based video card crashes
-Frequent driver failure for the video card
-The mouse cursor would jump to the edge of the screen
-The mouse cursor would change when browsing the web (ie, the hand point sometimes over text boxes, the typing cursor over non-textboxes)
-When alt-tabbing from facebook to World of Warcraft, the monitor would go into power save mode and not come out of it, requiring me to press the power button the PC to turn it off.
-Sometimes when shutting the computer down, the fans and front vanity light would remain on and not turn off (even after 10 minutes). This would require me to hold the power button down to power off. This would happen during Restarts as well--the system would not actually restart and just hang in this mode.
-I would experience system stutters: everything would freeze on screen for a few seconds. The stutters, once started, would happen every 30 seconds or so.
-Sometimes these stutters would result in a system freeze requiring a hard restart. (Sound would continue to play normally.)
Here are the steps I have taken thus far in very close order:
-Ran rKill, no problems detected (Problems persisted)
-Downloaded RevoUninstaller and removed Java, Flash, Video card drivers, and any programs I would not normally use with Moderate scans. (Reinstalled drivers. Reinstalled Java and Flash after problems persisted.)
-Downloaded Valley Benchmark to stress the hardware. No video crashes during the benchmark. (Problems persisted)
-Physically cleaned the fans and dust (there wasn't much at all) from the fans, the motherboard, and the gpu. (Problems persisted)
-Ran RevoUninstaller's evidence remover. (Problems persisted)
-Went into my power options and made sure that the monitor/system would never go into sleep mode. (Monitor no longer goes into power save when alt-tabbing to World of Warcraft, but the system still hangs on shut down and restart.)
-Installed HW Monitor to keep track of temperatures (noticed one 65 degree Celsius spike in a couple of the CPU cores while gaming in Windowed mode, 75C spike in the video card. Problems persisted)
-I took out the video card and cleaned it with extra care and made sure the connections were tight, I also updated mouse drivers from Razer. No problems for 1 day, temperatures were stable between 30-45 in the CPU, 60ish for the video card
-All problems have returned (except the monitor going to sleep, which has not happened since I turned off all sleep/power save options). CPU Temperatures have spiked to the low 50s once (video card in the 70s), but are usually in the 30-45C range (50-65 in the video card).
I'm not sure what else to do. I had 1 good day in the last 2 months and only after I blew some compressed air into the video card and checked the connections were firm. I do not have a spare video card to test. Wouldn't the benchmark have forced a hardware issue if there was one? I'm getting tired of these issues--they're very disruptive.
As a note, I do not have stutter/freezing issues while in game. I do have the mouse cursor issue (it appearing at the edge of the screen in game and in web browsing).
Any help would be greatly appreciated. Thank you.
