| 816184 | 2009-10-02 21:57:00 | I cleaned up (removed lots of viruses, trojan horses, etc) this PC for a friend of mine, everything was working fine after that. He took back the PC, plugged in all the cables, turned it ON but nothing happens - no beeps, no display, nothing, the fan is spinning, though. He brought back the PC, monitor back just now, and I checked and found that I could not plug in the monitor's signal cable to the PC properly. Checked and found that pin 6 (monitor cable plug) is bent and shorted to pin 7! Replaced another cable (from another computer - known to be good) and plugged in, pressed the power switch with high hopes but still nothing happens! Has this fried the MB? I removed everything from the MB - video card, ram, hdd, cdrom drive, etc. turned it ON and after a delay of about seconds, the beeps (short beeps) like 'crazy'. Is this a good sign? What shall I do next? |

| 816185 | 2009-10-02 22:11:00 | Pin 6 shorted to pin 7 shouldn't have caused any problem as they are red ground and green ground.(edit: for a VGA plug) Beeps are always a good sign :) I'd just reinstall enough to see if it tries to boot, like video card, minimal ram and maybe hard drive. |

| 816187 | 2009-10-02 23:00:00 | You will probably have to go through a process of elimination, like trying another video card, another ram stick, changing one thing at a time, leaving the HDD disconected. If there is more than one ram stick, try them each in turn. Maybe the techs can suggest a line of approach. |

| 816189 | 2009-10-03 01:22:00 | Here are the things that I've tried: 1. a 'good' video card; 2. a 'good' PSU; 3. Inter-changed ram sticks (2 x 256MB) & all ram slots (3 of them); 4. another RAM stick (known to-be good), tried in all 3 slots; 5. Another monitor; 6. A 'good' monitor signal cable 7. removed batter and reset cmos Haven't got a new battery to try on. |
