I'm hoping that someone might be able to help me with a problem on my system please.
I run a 1.5Ghz Pentium 4 with 512MB RAM, WinXP SP2. I have recently started getting a problem where my PC will just crash and freeze completely. It semi resembles the PC in hibernation mode, but without waking up. This can happen at any point, and any frequency. For example, this morning, it happened 3 times during 3 separate boot ups. Yesterday it happened when i was surfing the net using Opera, but I did have times when it wouldn't freeze, like for the last hour it hasn't frozen on me (yet). What happens is the PC becomes unresponsive, so no keyboard press or mouse click starts it again, the power remains on, the CD-ROM light stay permanently on and the screen goes completely blank.
I know I have enough power in the PSU, and the PC had no problems before, nor have I installed any new software, in fact I've uninstalled loads to try and sort it. I've run AVG, Spybot and Defender, but nada...
One other thing was around a month ago (when I didn't have a net connection temporarily), everytime I started my PC, it would have a pop-up box asking me to switch-to or cancel, the cancel was blanked out, and when I pressed switch to, the start menu popped-up. This doesn't occur now?
Any help on this would be invaluable... thank you!!
