hello. i built a computer for my friend a few years back, and now she is having issues with it just locking up. It will just freeze, all input (mouse and keyboard) is halted and the screen is just frozen. For the most part, it only does this in microsoft office, so i thought it was a software problem so i reformated, only it gives the same problem so now i know its hardware. Ive changed the RAM with no luck. Ive disconnected any unessary devices (floppy, USB devices, DVD ROM, ETC) yet its the same thing. MEMTEST86 says its ok, and the seagate hard drive tester says that its ok.
so now im confused on what it could be. Since it is freezing in office when typing, im guessing it could be a motherboard issue with the southbridge chipset? or it could possible be hard drive (if the tests were wrong), or PSU, or vid card? i have no idea but i dont want her to spend unessesary money. wat do you all think? Just a note, it does lock up sometimes out of office, but it does not freeze because of a heavy load on cpu or memory. Ive tryed stress tests on memory, hard drive, cpu, and the onboard cache and it never locks up.
specs are:
Celeron 2.2GHz
Asrock P4VT8+ motherboard (socket 478)
512 generic RAM
80 gig maxtor HD
nvidia MX4000 vid card
generic 480watt power supply
i am completely baffled.....
