Solved Computer is running slow and CPU usage 100%

Specs: Windows XP
I just recently got my computer back from having a D/C port installed in it. Today is the first day using it, and it is running extremely slow, also the CPU usage is running at 100% when I am not even doing anything on the computer, I assume this is because I have some type of virus, spyware or malware running in the background that I am unaware of. If anyone could help it would be greatly appreciated.

✔ Best Answer
Update all available definitions of your real-time anti-malware program, perform a full system scan, and report back the results. Follow that up with a full system scan of Malwarebytes Free, clean up the threats it finds, and report back the result. Lastly, do the same with SuperAntiSpyware Free. SAS is over-dramatic about tracking cookies. Delete those just fine and don't bother reporting them.

By 'd/c port' do you mean the charging jack on a laptop or is it some piece of hardware I haven't heard of? And the problem started just after you got it back?

If it's just a new charging jack then the shop had no reason to install any software or or make any hardware changes. But you can run MSCONFIG and click the 'startup' tab and see if you can tell if anything has been added. You can run a simple malware scan with something like malwarebytes:

and see if it picks up anything.

You can go back to the shop, tell them what's happening and see I they'll admit to doing something that may have caused it. Of course they'll say they didn't do anything but replace the port and have no idea what's going on.

Or it could be slowing down to conserve power and reduce heat:

You can restore your system, if that doesn't help then you can restart your computer in safe mode and then scan your whole system with your existing antivirus.
Always remind to use a trustworthy antivirus programs such as AVG,,, Bitfinder etc. they have their both free and paid versions.

You might want to try the following to troubleshoot to if it is a hardware problem or software problem.

Checking your Hardware
Yes, Physically cleaning your computer can help reduce the heat build up. If it is a laptop you can buy a fan to place under your laptop to cool it down. Check to see in your task monitor if you are using alot of RAM or cpu cycles. If you are using up a large percentage of your RAM you probably need upgrade to more RAM or use less programs at the same time. If you CPU is continously spiking, it could be your computer is overheating or you have a program that using it. You can try to find and kill it using your task monitor.

Cleaning Up Your OS
1) run chdsk on your harddrive to see if you have any bad sectors
2) try degfraging your harddrive
4) if using a lot of ram try uninstalling some of your unused software
You can try some software to fix some of these problem if you dont want to do it manually.
