Hello everyone, i am a new member to this community and i have a huge problem which hopefully i can get solved with u guys help. Ok, here goes. i build this system in May 2009 and it ran amazing untill a few days back(month of november). I woke up one day an i move the mouse but nothing shows. The screen had gone into power saver and none of the light keys work on the keyboard. I restarted it and it ran fr abt an hour when suddenly poof!!! BSOD. But before i could record wht it said, the message "dumping memory" started counting up to 100% and it restarted. SInce then these things keep happening. I wake up, its frozen, i restart , then BSOD, then restart again and it runs fine till evening and suddenly starts locking up again. Lately these multicoloured horizontal lines have started showing up and the screen freezes on that. Other than that random BSOD pops up and restarts but i get a glimpse of the msg which is different most of the time. Ex "somthing abt page fault in non paged area or kmod exception not handeled or irql not handled, then stop 0000007e somthing"...This gets incredibly annoying whe one is doing work or watching movies or playing games. I am perplexed because before a week back, the system would run faultlessly. Was is my fault keeping it going fr a few nights without rest. I did mem86 test and it showed no errors to ram but i did just one pass at it. The i tried 3D mark and FurMark as gpu stress testers and they worked fine. I did prime 96. The first time it ran, it gave me errors immidiately but when i ran it after that, its been working every single time. But i hvnt tested it through the night. I hope oyou guyz can help me out. I even cleaned the system and it didnt help.
