Need help with identifying and fixing the problem...

Im currently running Windows XP....Ive noticed that when I run World of
Warcraft on this computer(HP Pavillion a1477c) the game crashes, the
computer shutdowns tries to restart....but instead the tower makes a beeping
noise and the screen is black. Ive run the repair tool from the games
website...and it worked very well. Before the problem was much more severe
until the repair tool.

Instead of having to turn on the computer several times a day to get it
working...the repair tool helped to reduce by half the amount...

But the problem has returned and if anyone can tell me whats going on and
how to fix it, I would really appreciate it. Thank you in advance.

 

The symptom usually indicates a hardware problem. The beep sequence may
indicate which hardware has failed... HP would be the source for that
information. Since it happens in-game, suspect an overheating problem,
either of the CPU, system board or possibly the video card. Might just be
due to dust accumulation so the first thing to do would be open the case and
blow the dust off of all the fans and heat sinks (unplug the AC first of
course!). Blow dust off of pc-boards too but don't physically handle or
touch any components.

A relatively simple check for overheating problems (after cleaning the dust
out) is to run the computer with the side of the case removed and set up a
portable fan to blow into it. If the computer runs continuously without
shutting down you know overheating was the problem. At that point you may
want to have HP (warranty?) or a service shop check the PC for defective
fans, loose heat sinks, hopefully nothing worse.

 

Can't say I agree with that, more likely it's a hardware problem.
