Windows 7: PC slows to a crawl until rebooted, seemingly at random.

PC slows to a crawl until rebooted, seemingly at random.

This has been going on for about a week now and I don't understand what it is. Sometimes when I start the computer, log in, or sometimes just out of nowhere it just becomes unresponsive and I can't really do anything. Task manager, start menu, and anything else take minutes to load up. I've ran all kinds of tests, all of which passed, as well as formatting and reinstalling windows. I also have a 6 hour long test running right now called Hot CPU Tester Pro 4.

I'm at my wit's end. I don't recall changing anything that should have begun these crashes. I upgraded my CPU and PSU recently, but everything had been working great after I installed them. I thought it may have been updating my nvidia driver, but I went back to the previous driver and it's happening just the same.

Any ideas? I've tested the HDD, memory, and CPU multiple times so far with all tests passed. I don't know what else to do, or even WHAT is causing the issue to begin with.

Specs are

Phenom II X4 965 Black Edition Deneb
12gb ram
GTX 460
Biostar mobo
750w PSU

You have avast! and ad-aware antivirus installed. Remove one or the other. Having two security programs that accomplish essentially the same task in realtime can cause freezes/crashes/instability because they try to utilize the same resources or scan the same system files simultaneously.

HOTCPU is not installed properly. You receive a number of errors associated with it:
Log Name:      System
Source:        Service Control Manager
Date:          5/31/2012 12:04:22 AM
Event ID:      7000
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      Danny-PC
The 7ByteIo service failed to start due to the following error: 
The system cannot find the file specified.

I also see indications of possible registry corruption at the system level. You may need to Repair Install Windows 7.

my PC is doing it right now. it took me about 10 minutes to open task manager and to get back into this window. everything has frozen up for about a minute after each sentence that I've typed. it's like it's queuing up everything I've clicked, spending a long time frozen, then very slowly executing it all while freezing every 5-10 seconds. ugh it just froze for like 10 minutes.

okay, I'll get rid of ad-aware and hot cpu. though I had both avast! and ad-aware installed side by side for at least a year and never had a single freeze or slowdown or anything. and I'll try to repair install as well.

you don't think this is a hardware issue?

It could be hardware, but it does not give me that impression. I had similar issues due to various antivirus programs in the past, so I am inclined to believe this is software related. Also, antivirus software is constantly getting updated via the definitions and program updates to them, so they may work for some time and then suddenly stop working together due to one of those updates. You may consider removing both and then installing one at a time to test. If you remove avast!, make sure to use the avast uninstall utility.

I don't want to speak too soon, but since removing ad-aware and repair installing, I haven't had the issue yet. though it has gone this length of time before, so I'll have to wait until tomorrow or the next day before I can be sure.

That's good news that stability has been better so far. Continue to monitor and let us know in a few days how the system is responding.

I haven't had the issue again, do you think it's safe to say it's been resolved?
