Win XP Pro
Intel dual core
I don't really know too many other specs off the top of my head. The system is at least 3 years old though.
The problem started almost a week ago. No new hardware, no new software. It will reboot randomly sometimes giving me just a few minutes, sometimes giving me a half hour or so. There is no blue screen of death, no error message, no "windows did not shut down properly" etc etc. The screen simply goes black & then the boot process starts up.
At first I thought it was heat but as of now I have the sides off & even the power supply sitting outside of the case. The room itself is not warm.
Then I thought perhaps it was caked on dust. I got compressed air & cleaned out the CPU heatsink & all the vents & fans (case fans, heatsink fan, power supply fans)
Then I thought it might be the hard drive failing. I would hear a click every now & then when it was first loading up all the programs that start w/ Windows. I have 2 spare hard drives from my old computer & I reformatted & did a fresh install of Windows on both drives & still have the rebooting problem.
Then I thought maybe it was the RAM. I have 3 gigs in the form of two 1gb sticks & two 512mb sticks. I've tried it with just the two 512mb sticks, I've tried with the two 1gb sticks, & currently I'm using one 1gb stick. Still rebooting.
Then I was hoping it was the power supply. I took it to my local computer shop to have it tested & they say its fine. Of course they advised that it could be failing under load. I did notice burning smell that I never noticed before when I took the power supply out. I googled but all I can find on that subject is brand new PSU's "burning in." My PSU is far from new though lol.
I've disconnected most non essential components. (Disconnected devices: DVD burner, 2nd hard drive, pro audio card) (Wireless adapter is still connected, I don't have a video card or anything like that)
For kicks I've tried to run the system w/ firewalls & antivirus software disabled.
It doesn't matter if I'm using the computer (internet, running programs, etc) or if I simply just leave it on. It's going to reboot either way. I boot it up, go play xbox for awhile & when I come back it's rebooted (I can tell because I'll open a blank notepad).
I find it peculiar that it DOES NOT reboot if it's in safe mode. What's the deal with that?
So what do you guys think? The computer shop charges $45 just to figure out what the problem is. I hate to do that because if the total repair bill is going to be a couple hundred bucks or more I'd probably rather just get a new computer (I just now thought about this... if it's the mobo or cpu I'd have to have them install it & I'm sure they'd charge me another $30). Do you think I'm over reacting? Should I just take it in?
Thanks for your time
Oh yeah, I've tried to set it so that Windows doesn't reboot if it has a failure but that doesn't seem to take.
