If it is a BIOS beep, rather than a desktop/application sound, then you have |
| 11 |
some hardware problem. The recent update may have implemented some hardware |
| 12 |
acceleration rendering on the browser and this is putting pressure on your |
| 13 |
GPU, RAM, PSU. A single beep points to RAM, but I don't know all OEM's BIOS |
| 14 |
codes. |

I'd start by opening the cover and reseating your RAM modules. Oxidisation |
| 17 |
may have increase contact resistance. Usually pulling them out and pushing |
| 18 |
them back in cleans them enough to restore a good electrical contact. |

While you're there try removing all the dust from CPU, GPU, PSU coolers and |
| 21 |
air ducts using a vacuum cleaner (carefully) or a compressed air can. Keep |
| 22 |
holding the chassis at all times with one hand or use an earthing strap, some |
| 23 |
vacuum cleaners I've tried have a terrible problem with creating static |
| 24 |
electricity and a discharge could blow your MoBo chipset. |
| 25 |
|
| 26 |
Finally, reseat any SATA/IDE cables. Their contacts can also corrode with |
| 27 |
time and if the browser is caching pages on disk while the freeze occurs it |
| 28 |
might cause a problem, although unlikely to get a BIOS beep from it. You |
| 29 |
wouldn't be able to boot with a hard disk failure beep code going off, if this |
| 30 |
was your problem. |

This sounds like a Xorg drivers problem, but if Xorg has partially crashed due |
| 36 |
to RAM or power problems, then this cursor problem will go away after you |
| 37 |
address the hardware issue. |

What does /var/log/Xorg.0.log reveal? |
