I Have quite a hefty hardware error of some sort. Every couple of days, I'm on the computer and suddenly the screen shuts off, the light next to the button starts blinking like the monitor is in suspend mode, the computer is still on and running though. I restart my computer and instead of loading windows it goes into that suspend mode right after the windows loading screen. A few days later, it suddenly works again, without me having made any changes. It works fine for a few days (sometimes a few hours) before happening again. The only way I can log on is through safe mode, and when I load up it asks if i'd like to restore to an earlier checkpoint. I do so, but it resolves nothing. I've also tried restoring windows to it's "last working configuration" in the prompt screen before windows loads. I'm quite sure I don't have any viruses, and I recently reformatted in hopes of fixing the problem at no avail. Does anyone have an explaination to why this happens, and/or a resolve to the problem, direction to help for this problem, it's very troublesome and perplexing.

my first guess is graphics card overheating. Is it on board graphics or slot-in card? Does it have a fan on it, does the fan work (at high speed, not chugging around slowly), is it all caked in dust, is the case and vents in general caked in dust and kept in a place (tight corner under desk) where it can not get good ventilation

What model of mboard do you have? e.g. I recently installed Win Me on an Asus K7V and experienced similar problems though not a severe as yours - after looking on the web at a lot of posts I found that on that model the bios has errors in the instructions for Suspend/Sleep, even in the last bios version. After a few days of it going into Suspend mode for no reason even after I had turned it off in Control - Power Management, had disabled ACPI/APM in the bios Setup, and had unchecked the loading of the two loadpowerprofile lines in MSConfig - Startup which dsabled ACPI completely in Win 98SE on another computer, Windows produced a message that it had detected it was having problems with Suspend mode and did I want the use of it to be turned off - I answered yes and it's been fine since.

You also shouldn't overlook the obvious - monitor & its driver? A little history will also help us a great deal, has it always been this way, was something changed (added or removed hardware)?. The Secret Letter From Iraq

going along with what Cliffpage was thinking, i had a computer act the same way. It was the fan on the northbridge chip. It stopped working and the northbridge chip overheated and went to blank screen. Start the computer with the side panel off and make sure all fans are working.
