Hey everyone. Firstly id like to say sorry for if i have posted in a wrong thread/newsboard. Secondly id like to thank anyone who reads and responds to this post as it is much appreciated. I got an Acer Aspire AX1300 for Christmas this year and it is a great computer, however i am experiencing some problems and it is getting annoying now. The problem is that the computer keeps crashing. It could be if im playing a game, it could be if im on the internet, it could be if music is playing. It just happens randomly with no warning. The monitor (Acer X193HQ) will just turn a random color, usually the color is the most color on the screen before it crashes, mainly black, blue or sometimes yellow. The keyboard lights will just stop working too, if capslock was on and the PC crashed the caps lock light would still be on but i cant turn it off or use the other lights such as numlock. The mouse light would still be on also, however moving it makes no difference to the screen. Also the speakers (Standard PCLine speakers plugged into the headphone/speakers slot) Would just cut out, i knew this because if i was playing music or game sounds it would just stop when the PC crashed. The wierd thing however is that the CPU main light is still on, and the fans are still working. Its as if the CPU just cuts out all its devices. Here are the main details of the PC. Hard Drive Size: 320GB Hard Drive Type: SATA Memory Type: DDR2 Ammount of memory: 3GB Processor: AMD Athlon™ 64 X2 Dual-Core Processor Cache: 1MB Processor Model Number: 7450 Processor Speed: 2.4 GHz BIOS: )Phoenix - Award WorkstationBIOS v6.00PG Operating System: Microsoft Windows® Vista™ Home Premium (However i did install Windows 7 32Bit, then Windows 7 64Bit. Both legal and registered) Graphics Name: NVIDIA GeForce 8200 DAC Type: Intergrated RAMDAC Approx. Total Memory: 1394MB DirectX Version: 11 Optical Drive Type: DVD Re-Writer Number of USB Ports: 9 Product Depth: 35.2 cm Product Height: 26.5 cm Product Width: 10 cm Product Weight: 8kg Moniter: Acer X183HQ Moniter size: 19" Wired mouse and keyboard. Things i tried. I looked all around Google for help and got a few ideas however none worked. I installed the 64bit of windows 7 instead of the 32 bit and it did upgrade performance but still the same crash like it was in 32bit. I checked and updated all the drivers, both the windows ones and other drivers. Also i upgraded the graphics card driver, and for some reason it registered that my graphics card is a 9200 instead of a 8200, it said this on the nvidia control panel, and on dxdiag. However when i reformatted it said i had the 8200 one. As i said before i have reformatted the pc, iv done it about 3 times. One to install Windows 6 32bit then installed the latest graphics card driver which said i had a 9200, then again to Windows 7 32bit with the 8200 driver and hardly anything on the pc. Still kept crashing. I then formatted to Windows 7 64bit but it still crashes. Somebody said something about maybe the monitor cable wire isn't plugged properly, knowing it wouldn't be the solution because the other devices cut out too but i still checked the monitor cable. I also checked the CPU power cable and that is in a single plug and plugged in properly to the CPU. I had opened up the case and checked the fans they are all clean and functioning perfectly. Also i had moved the CPU to the middle of my table in case over heating was a problem. The computer is still crashing. I thought i would post here to see if you guys had any suggestions, if it fails then i might end up having to send the computer back to the manufacturer. I am currently having to use my 6yr old Medion laptop to do my GCSE school work and coursework because the Acer is too unreliable and has already lost a few of my files when i was working. Any ideas, even if your unsure would be a massive help for me. Also if you need any other details then feel free to ask.
