Computer Restarting Problem
(escuse my Eng, i am really sleepy) Straight to the point:
My computer is 3yrs old, but nothing is wrong with it, all the hardware are working properly, everything is connected properly, Using windows xp SP 3.0, and no, nothing is overheating. The restart is immediate, and only ever happen right after I satisfy above condition(s).
problems
A* My computer restarts on its own when using certain applications
- When using the autoplay for game "homeworld 2" (later I found, this was infected). However, if I start game by clicking myself, it works
- When starting an uptodate, registered version of "speedupmypc" from Uniblue (other software from same software bundle, "Driver Scanner" and "Registry booster" both work).
B* restarts when I am visiting certain parts of certain websites
- entering the "city" (multiplayer) in "deadfrontier.com (Other Online multiplayer games work fine though, Runescape is fine)"
- While trying to attach pictures on a yahoo email address.
What I did before problem.
1. Cleaned computer of junk using speedupmypc, registry booster, defrag, disk cleanup.
2. finished dl of cracked game Dawn of war 2 from vitality.
3. Unzipped and installed it, got a virus prompt for trojan, but i ignored it, and decided that I would rid of it later.
4. Installed game, but my graphics card was crap, and couldn't handle the graphics, so I quit and deleted all but the unzipped iso.
5. got Peazip, but computer had some unusal lag while installing it.
6. used Peazip once, on a MMORPG called "wakfu".
7. Computer got slower, so tried speedupmypc... which lead to a prompt restart of comp.
8. decided to surf web, and on certain sites, it just restarts, only on those sites.
8. Used bitdefender, malwarebytes, super-antispyware,mcafee, restoring computer to earlier time (selection is there, but did not work), reinstalled flashplayer... none worked
Help? what's wrong with my computer? Why is it restarting so promptly and selectively? Most importantly, how may this issue be solved?
p.s. Scar 3.21 now freezes for abit when I run a script on it (only for first time program run since last restart), and it has whole bunch of error message when I stop the program after some time of it running.
