Just a few days ago, again I happen to encounter a black-out CPU cause by a shorted reset button.If you troubleshoot the unit without disassembling or unplugging all front panel switches, chances are you will be mislead into believing that you have a defective motherboard.
Micro switches in CPU's accumulate dirt or stuck overtime(especially on cheaper CPU Casing) and will cause short circuit on front panel micro switches,it could be the power button or the reset button, and in this case its the reset button initiating a continuous reset of the motherboard as the CPU is turn on.
Next time when you encounter a black-out CPU, replace key components(mem,PS,processor) and still did not work, then this maybe your case.You can clean micro switches by dropping small amount of alcohol or spraying a contact cleaner on the top portion of a micro switch while repeatedly pushing the switch, if the latter still cause problem to the system you may opt to replace or just disable the particular switch.

Good day to all my readers!Its been quite a while that I have not updated my blog,cause I been kinda busy for the past couple of weeks.
Today I will discuss a solution to one of the most common problems end-users and PC repairman encounters in a PC and this is the WGA(Windows Genuine Advantage)notification.Huge volumes of PC around the globe(especially from 3rd world nations)has an unlicensed Windows XP installed in it,and some of it automatically downloaded this small WGA apps from Microsoft server informing you that "you may be a victim of piracy.....blah...blah..." during startup and its annoying.
There are options in combating such situation,you either buy a license copy of XP(expensive one),reformat your hard drive and re-install everything(long process) or delete this notification thing and everything will be back to normal(recommended).
Their are different ways in disabling WGA notifications but some of them are confusing and has hard to follow steps, making it difficult for an end user to perform.Just recently I just found out an easier way to get rid of WGA notifications and I will share it with you(in case you don't know yet).
Following three simple steps, now you can get rid of this bugging Windows Genuine Advantage (WGA) notifications:
1. Reboot Windows in safe mode (hold the f8 key while booting and you will get the option to boot in safe mode-just after POST)
2. Open Registry Editor (regedit.exe) and search for wgalogon folder and delete it. IMPORTANT-You should backup up the registry beforehand, in case something goes wrong.
3. In your windows directory search for files wga* and delete them(all).
You are done,reboot your system and everything should be back to normal.
'Till on my next post,happy weekend!
