Hey there. I bought a brand new Dell Inspiron 1520 laptop in May and it is now extremely slow to start. When I say extreme, I mean it can take up to 5 minutes on the Windows loading screen and when I open my session, it takes a good 5-10 minutes before it starts to run properly (i.e. not unbelievably slow). I have done all that I know to fix it:

- Anti-spyware scan : Spybot - S&D;
- Anti-virus scan : Avira Antivir;
- Cleared prefetch data;
- Changed Windows styles to "maximum efficiency"
- Deleted temporary internet files;
- Program desinstallation;
- Registry cleaning;
- Removed icons on my desktop;
- Removed menu items in Start menu;
- Removed non-essential programs at startup.

Of course, all of the programs I have used were all updated prior to using them. I can see little to no amelioration and I really don't know what could cause this huge slowliness. I have way more hard disk space than I need (i.e. 227Gb total vs 201Gb free), I have 2Gb RAM and I am not running really demanding software (Firefox, Windows Live Messenger, MS Word / Powerpoint are what I use 95% of the time). I also checked the CPU usage in the task manager but everything seems fine to me. The only thing I see is that whenever I watch a video in Firefox it peaks to about 35-45% CPU usage. That seems a bit much but I really don't know.

Does any of you guys have an idea what could cause this problem ? I really am tired of it and I need my laptop at school. Thanks to holidays I will have two weeks to fix this issue.

My computer:

Windows XP Pro SP2
Dell Inspiron 1520
Intel Core 2 Duo T5550 @ 1.83Ghz
2Gb RAM, 230Gb hard disk space

Any idea or suggestion is much welcome.

Thanks : )
