I'm having some strange issues with a eMachines W3052 running Windows Vista. Just recently it started blue screen with Stop 0x000000C2 error. After this more random blue screens came and other issues. So far I have come across all of the following issues.
Stop C2 - In Windows only
Stop 8E - In Windows
Stop 44 - Windows Boot
Stop 50 ecache.exe - Windows Boot
Stop 7b ntoskrnl.exe corrupt/missing - Windows boot
Stop 7E - Windows Boot
I have tried
-Pulling all add-on cards
-Reseating memory
-Replacing memory with known good
-Unplugging all devices except HDD, Mobo, + PSU
-Replaced PSU with known good
I have also tried running
-All other boot options (Safe mode, directory service mode, etc...)
-Chkdsk /f (no issues found)
-Start up repair (no issues found)
-Ran HDD Diagnostics (passed short and long test)
Just recently when trying to boot into Windows Vista Repair (via cd) the computer will automatically restart before loading all the way.
All these issues occur on and off too, instead of consistently. So for 5 minutes it could continually reboot right when it starts to detect the hard drive (no bluescreen, no start up options), and the next it'll boot into windows just fine and sit for 5 minutes till it blue-screens.
If anyone has any suggestions, please let me know.

you can test if the hardware is failing by booting from a live Knoppix cd; if this runs fine, and does not reboot, your hardware looks good.

do i understand you correct when you say it keeps rebooting without a cd drive connected?
just to be complete, you can test your ram; best download ubcd, and make the cd to boot from it -then run memtest86+ : http://www.ultimatebootcd.
I think the board is a few years old (2-4).
Of the issues given by "BitsBytes..." the following are the major ones present.
System Faults:
Memory Test Fails. (Only BSOD point to Memory issues, memory passed memtest)
System randomly and/or constantly reboots itself.
Fails to fully boot (or even install) Operating System.
Random & frequent 'Blue Screens of Death'
BSoD or hard freeze under heavy drive activity (Either RAID, SCSI, or standard ATA)
The following ones haven't happened yet.
Motherboard fails to POST.
Resetting the system after a freeze and the system will not repost.
System randomly and frequently freezes.
And I can't test the following yet, or rather don't know how.
CPU temps abnormally higher than usual under typical or less load.
*CPU VCORE & other system voltages are erratic or far out of tolerances.
Also, it reboots sometimes wether or not a Optical drive is connected. Though when I run Windows Vista Repair lately, it will just restart while loading instead of loading all the way. So I'm assuming it would do the same with the regular Windows Vista reinstall disk.
The people from the link above .... they repair bad capacitors and guarantee their work for a year....... they actually use the "GOOD" capacitors and they are so sure and confident of their work that they will pay for the return shipping if anything goes bad on their work.....
If the cost of replacing the motherboard is more than repairing ($50 + s/h).... then repairing would be the way to go.....especially after considering that with the new caps it will be better than new and probably last you if not forever, at least very close to that....
It booted to the Knoppix fine, but froze short way in. I think I may have cleared up the issues though.
1. I reseated the CPU + Reapplied thermal paste just in case that was part of the issue
-That also set a more consistent blue-screening.
2. I managed to find 2 known good memory modules and tested them out. With the 2 different memory modules it seems to run stable with no apparent issues.
1 x 512, and 1 x 256 stick.
I think the issue when I originally tried the memory was that the 2 original memory modules were 256mb each. So when I tried each individually, neither would boot and brought up a Stop 7b error. I didn't even consider that this would be an insufficient amount of memory for Windows Vista to boot off and would cause errors.
So I'm assuming that both memory modules are bad and need replacing (with a higher amount hopefully).
I'm going to let it run for a bit first calling it good. I'll respond back a bit and close the question if this is so.
Sorry, let me further explain. I did replace the memory with known good memory. What I failed to do was match the size or greater. I replaced the 2x256mb sticks, with 1x256mb stick. With just the 256mb of memory, Vista blue-screened. I'm assuming because the min requirement is 512mb.
Sorry about the misunderstanding!

It sounds like you might have a bad capacitor. The symptoms:
System Faults:
Motherboard fails to POST.
Memory Test Fails.
System randomly and/or constantly reboots itself.
Fails to fully boot (or even install) Operating System.
System randomly and frequently freezes.
Random & frequent 'Blue Screens of Death'

CPU temps abnormally higher than usual under typical or less load.
*CPU VCORE & other system voltages are erratic or far out of tolerances.
Resetting the system after a freeze and the system will not repost.
(You have to completely power down then power back up.)

Is this an old board?
