Windows 7: Computer getting very slow, no virus/malware

Hey guys. My computer over the past few weeks has slowed down considerably. When gaming or doing anything else. Even when offline, files take a long time to open. Ive run several virus/malware tests, and everything came out normal. Any suggestions?

What virus scanners have you used? Have you installed any new programs?

Troubleshooting Steps for Windows 7

I used malwarebytes and windows security essentials. The MB found a bunch of bugs but when I cleared them it didn't make any difference performance wise.

I suggest you fill out your system specs. Follow the gregrocker tutorial linked to above.
In addition Optimize Windows 7
You don't want unnecessary processes running which some program installations will fire up.
I'd be checking:
1) status of your HDD/SSD. You can use something like Crystaldiskmark to check performance. Use the Windows or manufacturers disk check for a HDD.
2) status of your CPU. If Intel run the diagnostic program.
3) check gpu and cpu performance. I've used Cinebench.

Slight aside: I suspect Firefox has been causing me some problems of late. It's starting to crash a bit and been a bit sluggish. Others could comment but I'm considering Crome.

Establish a Clean Boot, run SFC /SCANNOW Command, check the logs for repeat errors, utilize System Resources to search for problems and solutions and Generate a System Health Report, test the hardware and the other Troubleshooting Steps for Windows 7

I'd take all the advice on board - some reinforced I guess. I'm curious about the suggestion to defrag the registry. Other opinions on this would be interesting.

If you use a boot time defragger like Puran free Defrag which gives you the most bang for your buck anyway since it hits all system files because they're not running at the moment, then that's really all you should need for the registry, isn't it?

I did use Auslogics Registry Defrag for many years but don't notice any difference not using it now.

TBH the only difference I've ever noticed defragging Win7 was when Cluberti suggested using a Boot Time defrag when a 2 minute boot was traced to System file fragmentation, and Puran cut that in half. I've been using it ever since.

But after years of debate here now about whether CCleaner cleaning and Defrag are really needed with Win7, I still can't say for sure that it's any more justified than not wanting to leave gigs of junk files (or Registry fragments) when they can be cleaned up safely, and that the Win7 developers felt it was necessary to schedule a built-in Defrag weekly. It may be habit. Persuasive argument has convinced me Win7 doesn't know from leaving registry shells and may not even care about file buildup.

I like the boot time defragmenter in Glary Utilities.

OP has not responded in 3 days.

Yes, the problem is that win 7 gets slower and slower with time. There are many reasons for that. An average user has little influence and understanding of the boot process and other processes that take place on our computers. It is so because users are turned into dummies and only what they know is to change colors or some stupid effects that have nothing to do with the real functioning of win 7.
