Ive been experiencing computer issues with my computer since the first year i bought it back in 2004.The sound devices have always played up despite updating it with the relevant drivers from the official websites and trying countless driver packages, nothing works.I went as far as to install two totally brand new 1gb RAM , whilst removing the old 512 that was in there.On top of this i have installed a new harddrive of 320Gb.I thought that maybe my RAM was failing and that my hard disk may have been corrupt.This was not the case.
Here are in full detail , all the problems im having.
-No VGA driver installed/when installed , comes up as an (!) in device manager
-Realtek Audio 97 drivers installed but no sound device detected.
-Can occasionally hear system sounds , but it comes and goes
-Have driver detective installed, but will now not open and errors saying "please set reigstry key hklm\software\microsoft\.net framework \installroot to point to the .NET framework install location."
-Constant random reboots , blue screen which says one of two errors
either " IRQL NOT EQUAL" error or " PFN LIST" error.
-Ive tried running memtest through cd-rom and usb, but neither will work for some reason.and the machine continues loading windows.
Here is my computer spec
(which is now 320 gb SATA hardisk with 2GB ram and service pack 3)
ANY HELP WOULD REALLY BE APPRECIATED.
