Hey all, I'm having one of the weirdest issues with my computer at the moment that I can't seem to solve. I apologize if this is in the wrong section but since the problem seems to span a multitude of issues (hardware, software, OS etc) I figured it would do just as well in this forum. The Problem: Recently I installed a new GPU into my system to which a few weeks later I noticed the OS (Windows 7 64bit) behaving awkwardly with programs. Some programs that I try to open do nothing but zombie on my processes tab in task manager and will never fully open. Even worse is the fact that I can't kill the processes in task manager. An example is Malwarebytes refuses to open but is stuck on the processes tab in task manager (oddly enough the moment I just wrote the previous statement Malwarebytes finally opened up, albeit about an hour after I had tried to open it and gave up). Some programs work fine, others tend to hang after a certain period of time. Other weird issues include the fact that I can't create new folders on my desktop, funny enough I extracted a tool to my desktop to help with checking if any disk drives are failing and after the program was extracted all the sudden "New Folder" magically popped up on my desktop. Also whenever I reboot my system it will get past POST into the Windows logo instantly restart and then ask if I want to recover or start normally. If I select start normally it loads Windows just fine. This behavior occurs every time the PC is booted up. Earlier I tried to open iTunes in order to put some projects on my iPod classic when the same problem occurred and iTunes refused to open. I tried to repair QuickTime to see if that would fix the issue, but again I was thwarted by Windows as the Install/Uninstall window from the CP was taking ages to load any programs (Almost 30 mins!) after which I tried to get back to "Computer" to view my drives to which everything was blank with the green loading bar at the top slowly progressing across. SPECS: Windows 7 64bit 16Gb Memory EVGA GTX980 4Gb GDDR5 Intel i7 3.5 Things I've tried: At first I thought it may be the main Windows (C Drive failing. But after numerous checks and reports it keeps coming back up healthy. In fact all the drives are healthy. I checked my installation and my boot sectors etc. everything checks out. I thought it may be the PSU with the new GPU installed but the PSU is 1200 Watts with the proper connectors in place so I ruled that out. I ran CCleaner to fix any registry errors and clean up any gunk, to no avail Reinstalled certain drivers such as my GPU and audio interface. Messed around with my USB connections by disconnecting any USB hubs and hardware (I produce music for a living, so I disconnected any keybords or MIDI controllers just in case) except my mouse and keyboard Ran a check with Malwarebytes after I finally was able to open it up and it came up empty. The problems still occur even with the old GPU installed for testing Ran an sfc scan, check S.M.A.R.T. signatures etc. everything checked out on all drives. The only thing I've narrowed it down to is something possibly fishy with my (C Drive since it seems most of the issues with programs are the ones installed on the (C Drive with the exception of Firefox, and a few other programs which load just fine. Also it may be something wonky with my Windows but again checking came up empty. Could be other things, not sure, but any help would be greatly appreciated!
