Prepare for a massive Wall of Text: Over the last few weeks, this computer has become more and more problematic. Just to get it out of the way, I can, with 99.9% certainty, rule out viruses or malware, as I'm extremely careful and use Malwarebytes, AVG, and Firefox with Noscript. My computer has been virus-free for years. Every scan (the above two, Spybot, Avira, Ad-Aware, Bazooka, HijackThis - all scans have always been clean for years). Keep in mind that this computer was functioning flawlessly up until this week. This hardware setup is from 2008 and I am using the same Windows 7 disc that I installed on it three years ago. This is the second format and re-installation since I built the computer. No problems the last time, which was about a year ago. About a week ago, I started getting random squeaks and buzzes out of my speakers - especially when a progress bar is moving in a browser. I figured this was a power issue. Three days ago, my Windows volume control stopped responding. I'd click the icon in the taskbar, and it would take a good minute or two before it would show up. Then I wake up a few days ago, and the computer is frozen and the speakers are making some freaky, possessed R2-D2-esque beep/squeak/buzz noises - almost like the on-board sound card is experiencing some power issues. Also, for the last few days, when Windows would start, it wouldn't be able to recognize my USB wireless adapter. I'd disable and enable it, and I'd get a "failed to connect to network" error upon enabling it. "Diagnosing" it would fail a few times, then succeed temporarily, and then it would disappear again, then magically the adapter would fix itself and automatically connect to my network about 10-15 minutes later. None of these problems were happening a week ago. It was running perfectly then. No hardware changes. No software changes. Then two days ago, I was about to go to bed and told the computer to go into Sleep mode. The screen went blank and I figured it was just shutting down some processes and preparing to sleep. However, I came back an hour later, and it was still on, so I turned it off manually and went to sleep. I woke up the next morning, turned it on, and it got to the Windows 7 logo loading screen, then suddenly a Blue Screen of Death appeared for a fraction of a second and the computer rebooted. It was stuck in a BSoD loop for a good 20 restarts so I selected the "System Repair Menu" option from the "Windows did not start correctly" prompt. None of the options helped or worked correctly. I couldn't perform a system restore, as it didn't detect any installed copies of Windows. I ran the "Automatic Repair" program from that menu a few times, but it eventually gave me a "Windows could not be automatically repaired" message. The slow stream of problems seemed to have escalated to what I'd call a catastrophic failure. The BSoD loops continued for a while, so I decided I'd see if I could boot from the Windows 7 disk. I made sure that the DVD drive was the top boot priority and opened the boot menu and told it to boot from the CD. However, it somehow went to boot from the hard drive anyway. So I restarted it again, and it magically made it to Windows. I took the opportunity to browse to the DVD drive and manually run the Windows installer, and after I did this and it told me to reboot, the installer finally ran and took an eternity to actually get started. However, the installation failed somehow. I ran it again, formatted the C: drive, and tried reinstalling it again, and it successfully installed this time. So I got into my formatted and fresh Windows 7 installation, and the volume control is working just fine, but I'm still having the network issue - including the fact that it fails after startup for 10-15 minutes then magically repairs itself and automatically connects to my network. Once I had connectivity, I activated Windows, thinking that the problems I'm about to describe are because perhaps Microsoft limits your performance before you activate; this is not the case. What is truly frustrating, however, is the fact that this fresh Windows installation is mind-numbingly slow, both hardware and network wise. The online Google Chrome installer was hung (not frozen, but not progressing) for a good hour before I finally closed it. Windows Update has been stuck at 23% and I can no longer open the Windows Update window from the taskbar icon (if I end the process in Task Manager, it just re-opens a few minutes later and hangs at 23% for hours, though the process isn't frozen as I can still get the percent completed pop-up to appear when I hover my mouse over the icon). Because Windows Update isn't working, I can't see if any updates or Service Packs might fix this. Internet Explorer (nothing else to use, since installers are all hanging) takes about two minutes to open, and freezes for a good minute when I try to open a website or the options (or change tabs in the options window). Even Task Manager is slow and takes about 30 seconds to close a process. It takes 10 seconds or so to open a folder in Windows Explorer, and doing things like opening the "Save" window in Notepad, or pressing "Save" are now taking seconds when they were previously instantaneous. The nForce 650i Chipset driver installation took about an hour as each driver installation hung (but didn't freeze) at 30% for 20 minutes or so, but finally finished - but no effect on the slowness. I can't really test the effects of other drivers at the moment, as their installers are just too slow and unresponsive to ever finish. I downloaded the Google Chrome Standalone Offline Installer, and clicked the icon. "ChromeStandaloneInstaller.exe" appeared in Task Manager, and five minutes later "GoogleUpdater.exe" finally showed up. However, no actually installer visibly opened. Fifteen minutes later, an installer finally appeared, hanging (but not freezing) for another fifteen minutes. It just now finally finished and Chrome was successfully installed. Contrary to what you'd expect from Chrome, it's taking several minutes to start, and is running about as slowly as IE, with the welcome page taking a minute to appear the first time, and then not opening at all, and browsing is very slow as well, both software- and latency-wise. It seems as if both my computer AND my computer's internet access are suddenly slow after this reinstall (but the internet is just as fast as usual on my other computers, so I know it's an issue with my computer rather than my ISP or router - the other computers are crappy 98/XP rigs but all running faster and getting faster internet than my 2008 powerhouse is running right now). It took about five minutes for the registration page for these forums to finally load, and the page (but not the browser) actually froze several times for 30-60 seconds during the loading. Other websites are behaving similarly. This thing could smoothly run Crysis at high settings before, and now after a format and fresh installation of Windows, it can barely open a web browser. The CPU usage in Task Manager is stuck at 0% (not sure if that's right), and the Physical Memory usage is hovering around 25%. The Hard Disk activity is reported as 100% in the Resource Monitor, and the HD light on the front of my case is constantly on no matter what I'm doing. I just tried to close Resource Manager, and it hung for about 30 seconds before closing. I finally got Defragmenter to run after several attempts, and an analysis of the C: drive says that it's 1% fragmented. I don't know if this is considered high. However, as I did a "Slow" format of the C: drive before reinstalling the OS, I assume any existing fragmentation was made irrelevant since all data was erased. Could a 1% fragmented C: drive cause this slowness? This is probably irrelevant, but I had a 5.5 Windows Experience Score before the re-install, and now it is a 1.2. I'm not sure how it would drop so much with no hardware changes. All four sticks of RAM are recognized by Windows, so I don't think any of them have failed. Specs: Windows 7 Home Premium 64-bit Intel Q6600 ASUS P5N-e SLI motherboard 4GB of RAM (whichever type the P5N-e uses... can't look it up at the moment) nVidia GeForce GT240 (1 GB) Two 250GB Western Digital hard drives Rosewill 700W PSU Lite-On DVD drive 12Mb Comcast Cable Internet None of it is, or ever was, overclocked in any way. I have no idea what is wrong with this thing, and it's really getting frustrating, especially since I was laid off and can't afford to replace any of the hardware right now if this is a hardware failure. I'm considering trying another format and reinstall, though I'm not expecting different results. I'm sure I left something out despite this being an excessively long and wordy post, so if you need more information, please let me know. I hope this is the best possible forum for this issue, because my computer and internet are now too slow to find any other forums.
