Hi there, my computer restarts randomly and has done for around 3 years. I have took it to numerous people to see if they can fix the problem and have spent over £200 in doing so, but not one of them has been able to. I have all the lasest software / drivers and i have 3 fans in my pc, it does'nt even get warm. Microsoft Windows XP Version 2002 Service Pack 3 AMD Athlon(tm) XP2500+ 1.83GHz 768 RAM When my computer restarts i get a blue screen with and error code, i have written down two of them Error 1: ***STOP: 0x0000007E (OxC0000005, 0xF7902A74, 0xF7902770) ***Portcls.sys - Address F6E0746D, Base at F6E07000, Datastamp 41107F13 Error 2: ***STOP: 0x0000007E ( 0xC0000005, OxF6DA346D, OxF78FEA74, OxF78FE770) ***Portcls.sys - Address F6DA346D, Base at F6DA3000, Datastamp 48025CCC --------------- My computer will restart randomly, it could happen when i just start it up or 30 mins later. I have scanned my computer with Norton Anti Virus 2008, AVG Antivirus, AD Aware and Spybot and none of these find anything. Please help i have ran out of options, thank you.
