I built my PC with the following components a year ago:
- Intel i5-3570k
- ASRock Z77 Extreme4 Motherboard
- Corsair Vengeance 2 x 4GB
- Sapphire AMD Radeon HD6870
- Western Digital Blue 1TB Hard Drive
- Corsair Builder Series CX500 500W Power Supply
- Windows 7 Home Premium
After I had finished my PC build last May/June 2012, the computer has been running smoothly with no problems. However, starting around February of this year, things started to go downhill.
First, when I turned on the PC, the motherboard manufacturer logo/splash screen didn't go away after a few seconds. It would hang at the ASRock logo for about 30 seconds before going onto the "Starting Windows" screen. Here, it would be stuck for 2-3 minutes. Finally, the Windows logo would appear on the screen and would animate for about 30 seconds. The login screen appeared shortly after.
Not only did the boot slow down, but the shut down sequence as well.
The overall performance would slow down as well. Opening folders such as My Documents would take 2-3 seconds. I would see a progress bar after opening "My Computer". I would have to refresh/F5 folders in order to update them (such as after copying a file into the folder).
I know what most of you are thinking -- Virus, Malware, etc. I reformatted the hard drive and performed a fresh install of Windows 7. Still had the same problems.
At this point, I thought it was the hard drive. Luckily I still had an active warranty, so I had filed a RMA to receive my new hard drive.
I received it last week and installed Windows 7 today. STILL, I am having the same issues. Slow boot, hangs at start up, slow performance, etc.
Now I can look at some of the other components, such as the motherboard or memory. I ran MemTest to see whether or not my memory modules might be bad. MemTest failed to return any errors. I also swapped each of the memory modules from slot to slot, and one by one to rule it out. I will most likely borrow a couple of memory modules from my buddy tomorrow to make sure.
Right now, I've narrowed it down to my motherboard. Does anyone else think this might be the case?
