Ok, so I finally got frustrated enough to reinstall Vista today. I had been hoping I wouldn't have to, but it got to that point...you know, THAT point. Things were so slow and nothing seemed to work how it should have. Well, I reinstalled, Vista Ultimate x64. Plugged back in my 3 other HDDs (I have to unplug them during the install or when it restarts halfway through it tries to boot the IDE drives instead of the SATA one.) Set everything up the way I like it, my homepages in IE, etc. etc. Well, I go to install some Windows Updates, and there are a lot of them, and the thing locks up (explorer.exe, not just update). I tried ending the explorer.exe process and it closed everything along with my icons and my taskbar, but it still showed up in my task manager. I turned off the computer the old-fashioned way (you know, holding the button for 5 seconds). I took it apart completely and cleaned it inside and out. Took both side panels off and the front cover, cleaned dust from the fans, PSU, heatsink, graphics card, and case. Cleaned the old silver thermal compund off my CPU and heatsink and put new stuff on, replaced everything and turned it on. Well apart from a few mistakes like putting one of the fans on backwards (it's supposed to blow out I had it blowing in) and 2 of the fans being annoying as hell with their ticking sounds (I still don't know why they do that), it turned on just fine. I load it up and try to install Sony Vegas 8.0, my movie editor, well I have some problems entering my authentication code because it never asked me for a serial number...well, I fixed that and I go to install the updates again...gets to 46% installing the .NET 3.5 update and freezes. The progress bar is still going, but when I click cancel it doesn't do anything, and when I try to close the window...nothing. At this point I'm getting pissed. So I restart my computer, the thing takes 10 minutes at the stupid "windows is configuring updates" screen before shutting down, then another 10 minutes after starting up to "configuring updates" again! Now I'm really angry. Ok, so I calmly walk away, have a smoke, pet my cat for a while, and try again. This time the updates install, but 41 updates takes almost an hour to install (that's not including download time, that went in about 5 minutes for about 181 MB. MS needs to speed up their update servers). Just the install time took almost an hour. So, frustrated at everything, I decide to try what made me decide to reinstall in the first place, rendering out a video in Vegas. I chose the shortest video I had ready, 27 seconds. Rendering to WMV at 5Mbps and 1280x720 30p it took 8 minutes! 8 minutes to render 27 seconds! That's rediculous. This computer used to be able to render 27 seconds in about 30 seconds. 8GB 6400 RAM 3.0GHz dual core CPU (AMD Athlon 64 X2 6000+) I was rendering from a 1TB 3.0Gbps SATA HDD to the same HDD (and I also tried to another SATA HDD, 3.0Gbps, 500GB, same thing). I'm getting really really frustrated. Another thing bugging me is hwo quickly the space on my C: drive dissapears. I install small programs to the C: drive, but games and stuff go on the 1TB drive. When I was finished reinstalling Vista I had 16GB free, now I have 1.54GB and the little bar is red. I hate that, all I did was install updates! Please, if anyone knows what might be a potential problem, or something I can do to speed it up, please PLEASE help me, I'm abou to throw this thing off the balcony. That would be bad because I've put about $4000 into it monitors and all. Ah this is insane!
