Hi everyone, I'm Matt, I'm new here so Hi :D
Apologies if this is the wrong place, but seemed the most appropriate place to post for help.
Bear with me, this is probably going to be a long post, but I am in desperate need of help if anyone can offer any.
OK, a bit of background:
I am running a reasonably new (less than a year old) tower, Windows 7 Ultimate 64 SP1, AMD FX-4100, 8GB RAM Single Channel DDR3 @ 803MHz (4-5-5-15), 1TB Seagate ST31000528AS ATA with 645GB of free space [all taken from Piriforms' 'Speccy' software - Please tell me if any more information is needed]. *I can post screenshots of all the Speccy screens if needs be* I am also on BT Fibre Optic Broadband, with supposed speeds of up to roughly 50mb, connected via ethernet.
I have Avast! free antivirus, Avast! Grimefighter, AVG free antivirus, Malware Bytes, BitDefender, Piriform CCleaner, Piriform Defraggler as well as Windows Defender and Windows Defrag. [Generally speaking, I only use Avast Antivirus and Grimefighter, CCleaner and Defraggler and Malware Bytes, but it doesn't hurt to be careful, right?]
All was running well up until a few weeks ago, when I started noticed it slowing down a fair bit during internet usage (videos etc). I also had the 'Windows Start Up Repair' option appear several times. I ran it and it was working for 3 days straight with no end in sight, but needed to use PC at time so had to power off and hope it worked when I turned it back on. It came up with the option to do the start up repair again, or just start windows normally, I chose the latter, and it loaded up Windows, (though it gave me the option again next time I turned it on).
I ran a few scans with CCleaner, deleted all the unecessary files that were found (about 600mb) and carried on. I do a virus check most, if not every day, and nothing. It has got much, much worse since then, chugging to basically a standstill at the mere attempt at opening Spotify, or any other program really. It seems to give the 'not responding' message at pretty much every program opened, hangs for a minute or two, lets me carry on, then will probably repeat the process. This obviously makes doing anything on the machine very difficult. I have tried to watch several HD (720p usually) movies and tv shows since, and it takes ages (sometimes minutes) to even open the file. And when it finally does, it stops and stutters and sometimes even loops over and over (using VLC player, though have tried many others and problems persist. Though I know it's not the files themselves because it happens at different parts for different players). Have tried uninstalling and deleting everything, then reinstalling but problems persist.
Also, doing anything on the internet seems to take forever, again, sometimes being minutes to open pages. I am using Chrome as my default browser, but also have Firefox and IE installed just in case), and it basically can't seem to do anything without taking forever. Even simple pages like IGN, or Facebook can take ages to load, with the videos not playing correctly sometimes. It seems to struggle less with Firefox, but I much prefer Chrome. I have uninstalled and reinstalled both browsers but nothing changed.
I have ran many, many antivirus tests with all of the above software, found nothing. I have ran Grimefighter a few times, and although it said it removed many items, it hasn't really done much in terms of performance. I have defragged (and Defraggled...) the machine twice, and it hasn't helped. I have used CCleaner for registry file checking, as well as CHKDISK (I think it's called?) and another tool that I can't remember the name of at present. Everything seems to be as it should, with no problems or errors, yet my PC still is running at a terrible pace. I don't know what else to try as everything is seemingly normal.. I spend quite a lot of time on my PC, and would love to have it up and running as it should be again...
When (if...) it IS working, everything seems to be working fine...but when it decides it's not going to play ball, well, that's why I'm here..
If anyone has read this far, thanks, and if anyone can help, thanks even more!
