Hello everyone, I've came across some difficulties with my PC. So I've started a topic a few days ago in the "Virus and Malware Removal" section of this Forum. Under guidance of Broni from this forum, I have took some certain steps which you can follow here: http://www.techspot.com/vb/topic160141.html Unfortunately, my PC still keeps freezing. So i got tired of it, and decided to format my C: Drive. Fortunately for me, I have an external Hard Drive where I have saved all my Projects, Mp3, Movies, Pictures, etc etc.. So it was not that big of sacrifice. But after Installing Windows XP clean, I started to update my "Windows Updates" first from the Windows Update Website. After all that was done I began to install only the necessary programs like Avast Anti-Virus & Malwarebytes Anti-Malware. So when I went to bed I thought let's scan with Avast via the Schedule Scan. Tis seems to be an option that scans your Windows before it starts up. So i thought not a bad idea.. When I woke up and looked at my PC, it was frozen again. So I had to reboot my machine, after it was rebooted I looked in the Log file of the scan, and there Avast had found a few treat's. So i chose delete them, rebooted my PC. And a little time after it was rebooted, frozen again.. When i did a little search, I came across some interesting things. I first wanted to lay it down on you and hoped for your advice, since i don't know what to do.. So I read a similar problem here: http://www.techspot.com/vb/topic26226.html One talks about setting timings for CPU and Memory, also Jumpers of the Motherboard? The other claims it could be the video card.. I found this link also interesting: http://www.wisegeek.com/what-should-i-do-when-my-computer-freezes.htm Here is claimed that Bad random access memory (RAM) modules can also cause freezes, though RAM usually doesn’t “go bad” once installed unless damaged by overheating. Improperly adjusting BIOS clock settings for over-clocking can also cause problems, including freezing. And here: http://ezinearticles.com/?Why-Does-...---A-Guide-to-Fix-Computer-Freezes&id=1577900 They are saying that it could be a sort of messed up Register, that unwanted info there can make freezes and that via registry clean up tool it could be fixed. Here also a similar tool: http://computerfreezes.net/ But since Broni adviced me earlier to stay away from that kind of tools I stay away from it. Just informing you guys what i came across while i was doing some research. To me it is to much tech detail. I'm sure it says more to you then me So therefor, hope you can show me "which door to take".. Therefor Broni have forwarded me to this section of the forum. Maybe some one who can help me with this situation? I mean it is kind of irritating. Looking forward for any kind of reply! Thanks in advance.. Cheers!
