Security Center on Windows XP SP2 Freezes PC

But how many hours are you online Daily? i am some time around the clock 7/24 but most days from 11 am to 23 pm or 2 am 15 hours every day i am a power user and i use a lot of programs and have 10-15 windows open the same time write emails and use webmail,write in wordpad and listen to Internet radio the same time and some time i also download linux distro because i want to run multi OS on the same pc.

I use my laptop for all kinds of things. VMware, Photoshop, Outlook, surfing, music, chatting, and anything inbetween. Usually, I'm running a VM with 512MB of RAM while chatting and watching videos. Sure, the memory available at that point is low, but that's to be expected. Oh... and I reboot once every 2 weeks. In between it's hibernation.

On startup, as per the performance monitor, I've got 734MB of 1024MB of RAM free. That includes the ATI Control Center, as well as everything else I need on startup. %Commited bytes in use sits at 10%.

I can tell you for a fact that Windows is the best OS in terms of all around processor scheduling (at least for consumer OS's) and memory management. In one of my computer science courses (on Operating Systems, imagine that), we tested the processor scheduling of WindowsXP, Solaris, and Debian Linux. The program was designed to create 10 copies of itself (so you'd end up with 10 instances of the program), all with the same priority. Then, each instance was to keep adding 1 for a period of time (2 minutes maybe). When they were done, they would output the number they reached onto the screen (terminal, command line, whatever).

Windows: All 400,000 +/- 300

Solaris: Min 250,000 Mean 420,000 Max 650,000

Debian: Min 70,000 Mean 380,000 Max 900,000

You can see that Windows does the best job in distributing the processor load amongst the 10 instances of the program. There are several other tests you can do to compare the performance across OS's, but for the most part, Windows comes out on top.

And as a general rule of thumb, if your peak commit charge is higher than your total RAM after your normal usage of the computer, you need more RAM.

Now... to get back on topic.

If you've tried reinstalling, I'd also say that it's possible that your installation CD has corrupt files. You might want to contact Microsoft to see if you can get a replacement CD sent to you. Going beyond that would be somewhat excessive troubleshooting at this point.

No i have not setup any kind of performance monitor tool? and i just got a new XP Home CD with Service Pack 1a on from Dell in August this year so i don`t think the CD is ok?
