for what u say blue, purple screen, do u mean completely plain blue/purple with no single word, no white spot, no flickering colors?
and how long will this screen stay? forever until u restart?
will the screen change to another color if u let it stay?
did computer actually froze and hang?
what exactly are u doing with the comp at the exact moment it shows this screen?
if computer didn't hang and actually be able to function then it's video card, could be software side, which may be driver corruption or conflicts with computer data files, or could be hardware side, which may be overheat or damaged video card
if computer hangs too, then it's either video card or harddrive or both
video card, same thing, driver, conflict, overheat or damaged,
hardrive software side, installed things or system files corrupted that cause confliction with video card driver,
harddrive hardware side, overheat, badsector that cause invalid input to video (if input is valid, code will not jump to exception, so it won't hang, therefore if system did not hang, it won't be hardrive problem)
if screen contains flickering images and system did not hang, then it may be monitor too
these ar more general reasons, if u answer my questions at the top and provide a more detail description on the situation, then i can give u a more detail and more accurate reason to ur problem
for system slow startup, most of the common reasons are:
1)corrupted drivers, may check if safe mode is slow too,
it safe mode is fast then, it's drivers or startup application/service problem
2)corrupted system files
3)lack the habit of defragging and computer have been using for quite awhile with heavy data transfer duties
3)hardrive badsectors
4)windows have a prefetch function on startup that make things slow when u have alot of things to prefetch(which happens when u have been using the comp for a long time)
if u can specify exactly when does it get slow when starting up (EXACTLY when) then i might be able to tell u what's most likely the problem is since windows ar designed to do certain function at certain time, i would no what kinds of function is it loading during specific time

Hi Numbie (hope u won't mind I address you as this name),
I appreciate very much for your help and thank you very much for your detailed explanation!
Q: for what u say blue, purple screen, do u mean completely plain blue/purple with no single word, no white spot, no flickering colors?
A: Yes, it is completely one color, no any pattern on screen. Usually plain blue (but not the same color as DOS blue screen) or plain purple. It also become plain green apple color or grey color too.
Q: and how long will this screen stay? forever until u restart?
A: In my memory, the longest time I waited to see if any changes was about half an hour. After half hour later, the screen stayed the same color (if it was blue, it remained unchanged). Then I pushed the power off button to turn off the machine, and wait about 3-5 mins to turn on the laptop. The laptop would then go back to normal.
Q: will the screen change to another color if u let it stay?
A: No, it won't. ( But the maximum time I let it stay was only half hour.)
Q: did computer actually froze and hang?
A: I have no clue because nothing on the screen suddenly, just only one plain color. All I could notice was that the hard drive light was flashing. The speed of the flashing rate was similar to the speed when I am using application or web surfing.
Q: what exactly are u doing with the comp at the exact moment it shows this screen?
Ans:
Situation 1 (about 2 weeks ago): I was putting the laptop on my bed and browsing internet by using Firefox with about 5 tabs opened, and Windows Live Messenger. About 2-3 hours later, the screen turned to plain color. But I couldn't recall what color, maybe apple green, purple, or blue. (I usually put the laptop on my bed when in use. After couples of time with the same problem, I was afraid it was caused by overheat. I then put it on the desk every time when I use it.)
Situation 2 (one week ago): I put the laptop on the desk. I opened about 5 tabs with Firefox browser, and was using Q9 Chinese Input (九方香港版) to write post on Lips Corner. After about 2 hours later, the screen turn to plain blue. (This happened a week ago, after that, it doesn't happen again.)
To be precise, the first time of this screen problem happened was after about 8-10 months I bought this laptop. At that moment, I noticed that I had too many photos in the hard drive, made it slow and sometimes hang, I then burned all photos to disc, and reinstalled XP. After that, I changed my habit to save photos on DVD instead of hard drive, it still happened maybe 2 or 3 times in the next 2 years until recently.
During March to now, the screen problem has happened about 10 times. I couldn't recall all the details now. But in thess 2 months, I have been installed(in-) and/or uninstalled (un-) some programs, would that cause the problems? Those programs were Northern Anti-virus (un-), NOD32 anti-virus (in- & un-), AVG 7.5 anti-virus (in-), ccleaner (in-), Q9 3.0 Chinese Input (九方香港版) (in-) , AIM (AOL Instant messenger) (in- & un-), WinAVI (in-), VSO ConvertXtoDVD (in-), Spybot-Search and Destroy (in-), Quick time (in- & un-), GOM Player (in-), Sony Ericson PC Suite (in-), Adobe Photo downloader (in-), WinRAR(in-), pplive player (in- & un-).
My machine getting slower and slower in these few months. It gets extremely slow during the following periods:
1. In between the time after pushing the power on button (black screen) and appears the windows xp logo, and then;
2. In between the time of desktop background color has shown and the desktop icons appears, and then;
3. While opening some of the lower right-hand sided shortcut programs, they are MSN messenger and AVG 7.5 anti-virus.
Besides, when I open MS Word, it is really slow. It usually takes 10 mins to finish loading the application. Sometimes, after the program finished loading, I start typing from the blinking cursor, but no word shown on the page. I then click on the white space of the page and type again, if no word found, I redo "click and type" again. After several times of try, it will display my typing on screen.
