For the past few days i've been having this problem where seemingly at random, my PC freezes up then immediately proceeds to the Blue Screen for a memory dump. After that, I usually can't reboot the PC for a few minutes because it says to me that "Internal Hard Disk Drive not found, press F1 to retry". It just continues to claim that there's no hard drive recognized for awhile. Eventually it begins to recognize it again and I can reboot the PC as normal until the next time is goes to blue screen which can happen whenever. It's most frequent during gaming, but not restricted to it.
It first happened when Dropbox tried syncing alot of file changes and for some reason my PC became very slow and then proceeded to the BSOD. I uninstalled Dropbox and it kept happening at random times, so dropbox isn't the sole cause. I've gotten rid of programs that have seemed to cause trouble in the past few days to no avail. Now today my PC every few moments begins to act very slow and begins to stop responding for a little bit. The programs I almost always have open when these blue screens occur is Skype, Steam, Google Chrome, and a game.
My PC is an Alienware X51 Desktop. Here are the Specs:
Operating System
Windows 7 Home Premium 64-bit SP1
CPU
Intel Core i7 2600 @ 3.40GHz
RAM
8.00GB Dual-Channel DDR3 @ 665MHz
Motherboard
Alienware 08PG26
GPU
1023MB NVIDIA GeForce GTX 650 Ti (Gigabyte)
Storage
931GB Seagate ST31000524AS ATA Device (SATA)
Unfortunately, I don't have any minidump files because I apparently didn't have the proper settings selected for it to make dump files. When it happens again, i'll be sure to post the dump files.
The temps of the PC are normal, so I don't believe anything is overheating. That said, I think it's most likely something up with the hard drive. I'm alot more computer illiterate than I should be at this point so i'm most likely wrong. I'm trying to backup my files to an external hard drive but due to how slow my PC is getting sometimes it claims it will take a day to do so. I'm on the verge of opening up my PC and checking the HDD to see if tightening it or cleaning the dust out will help in any way. I want to be sure of what the issue is before I go and replace the HDD.
Any type of help would be appreciated. Thanks.
