Hello,
during the last months I have had some troubles with my laptop. I have tried to solve the issues by myself but it's hard since I'm not that into computers. First I had some random crashes once in a while resulting in a blue screen combined with some freezes, though the crashes was most of the problem. I think I have solved the crash problem by using WinDbg to find out that fwpkclnt.sys probably was the cause of the crashes. I found out that it was related to Windows Firewall but I know I had turned it off when I started using F-secure. I checked to see and saw that it was on. I turned it off but the crashes still occurred. I used service.msc to turn it off and now I haven't had any crashes for at least 2 weeks.

Instead I have trouble with the computer freezing. It often happens when I log in around the time when my antivirus logo appears. It sometimes happens when I am watching youtube for some time (might not be that it is youtube causing it because youtube is where I spend most of my time on the internet). It can also happen if I leave the computer on and WALK AWAY for 30 minutes or so and then come back it has frozen.

When it freezes everything takes very long time to do, starting a program takes a couple of minutes and I haven't been able to turn it off "the usual way" but I have to hold the off-button to turn it off. When I open the task manager I can see that the CPU usage is low and so is the RAM. There is a LED next to numlock and capslock that is shining. I believe that it shows how much the computer is WORKING or something like that because usually its off or blinking slowly but when the computer freezes it is shining all the time without even blinking.

I have tried to use windows disk repair or what it's called, I have also used Glary Registry Repair but it hasn't helped. I have tried to use Hitachi's Drive Fitness Test but I can't manage to get it started (I have burnt a CD but when I boot the computer nothing happens).

I try to keep my computer as clean as possible deleting unused programs and using CCleaner once in a while. I also have defragmentation scheduled once a week. I use F-secure antivirus and firewall and do scans with Ad-Aware about every second week.

The reason I'm posting here is because I believe the HDD could be the problem but I'm not sure it just feels like that, do you think anything else please tell me so and maybe I can move this topic to another forum.

PS: I have two other problem that is not that urgent but would be nice if they are solved
1. My computer is much slower than when I bought it and
2. Sometimes my energysettings are changed from minimum processor activity 100% and maximum 100% to minimum 0% and max 0%, I have no IDEA why that happens. DSBy the way the hard drive is far from full 64GB/144GB in one and 0/140 in the second Quote

I have burnt a CD but when I boot the computer nothing happens

Or I unpacked it with WinRAR and then burnt the files to the CD, is that the correct procedure?

No.

If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.
You have to use certain program, like mentioned ImgBurn to make the CD bootable. You burn straight .iso file.
You have to use brand new CDR.
