Occasionally my computer likes to conk out on me. This is the situation: At absolutely any time, doesn't matter what applications are running, or how many, my monitor will simply black out on me. I'm using an HP Pavilion MX70 monitor from the old family set up on my PC, and the green LED on it signifies that it is connected and has power, obviously. But at any random time, usually very sparse between times, the monitor will seemingly just turn itself off, the LED goes orange signifying that there is no input. I can turn it on and off, and rarely the screen will come back on, only to find the resolution and colors have foobared, and the keyboard won't work. The mouse, once, has worked, but only left to right, not up and down. This is very rare, usually the monitor won't pick itself back up again. So, 99% of the time, I have to restart, which of course makes everything better again. I can't see how it can be the monitor or graphics card that is the problem, as after restarting it is all fine. It doesn't happen on certain programs or sites, it's completely random. My system specs are: AMD Athlon 2800mhz+ (@ 2.31ghz) with sufficient cooling from a CoolerMate IceCube (as recommended by Bit Tech ) DFI Lan Party KT400A mobo Crucial 1gb PC2700 DDR Ram (2x512mb) 120gb Seagate Barracuda 8mb cache hdd Asus ATI Radeon 9600XT 128mb Soundblaster 5.1 Live All my graphics drivers are up to date. I have not messed about with flashing the BIOS or anything, the slight overclock was done by a friend of mine. I am planning to buy a 36gb Raptor and a WD 200gb IDE hdd in the near future, which would enabled me to do a clean install of Windows XP Home on the Raptor. Does anyone know of the problem I am having, or know the answer? Or do you think I am wise to wait until format and start again, and see if the problem goes away? Cheers for any help or advice you can offer.
