Question about Microsoft Windows XP Professional With Servise Pack 2 (e8503040) for PC
My desk top changes the colour depth from 32 bit to 8 bit on startup, but only if I log in quite soon. If I leave the logon screen till the logon screen saver comes on and then log in the 32 bit colour stays on. It only happens in my user profile and if I create a new one for testing and log into that instead, everthing is ok. I also get randon no warning shutdowns, or the machine will just freeze solid. 4 seconds of death is the only optin then. It wont complete a virus scan (Various programmes) and also wont have anything to do with compileing and writing DVD`s. = instant freeze or shutdown/restart. Drives are new and file sys passes windows startup chkdsk with no errors. have changed the motherboard/memory/graphic card/tv card. at my wits end.
Your colour issue may be down to incorrectly configured graphics settings, make sure in properties the colour is set to Highest (32-bit). If that fails, you can use a new user account, drag your files over on the new account and re-do your settings and delete your old user account. As you have changed quite a lot of components in your computer, the only likely problem left is either a dodgy power supply unit or an overheating issue. If a power supply detects it has a fault, it will shut itself off. However, go to your BIOS and search through menus for temperature information (you can usually find it in the power section of the BIOS) and check if the temperature is abnormal. Anything like 75 celcius and above can cause the computer to shut itself down as a safety feature. On most motherboards, you can raise this limit so it shuts down at 80 celcius or 90 celcius, or not at all. 80 is the absolute highest I'd ever set a computer at, because the higher the temperature at that sort of level, the lower life expectancy your components will have. You may also have a faulty CPU as "compileing and writing DVD's" is very CPU intensive and can be causing the computer to die. Make sure your CPU is NOT OVERCLOCKED. If it is, take the overclock off.
