Hello
I have tried toubleshooting this problem my self with no sucsess, have tried taking computer to pc outlett to fix(they just formatted it and cbf seeing if it acually worked) with about the same luck, so hopefull there will be a smart puppy out there somewhere
I have run Vista home premium 32bit for a while, but now have decided to upgrade my pc with
Mother- Gigabyte Ga-EP45-DS3R
CPU- Intel Core 2 Quad Core 2.83gHz
GPU- ATI-HD4870X2 2Gb Pci-E
MEM- Corsair 4GB kit Twin2x4096-8500c5df w/fan
HDD- Samsung SATA2 160GB
Pwr- Thermal Take "tough power" 750watt
Case- Antec 900 Gaming Case

And heres the Problem:
I Installed XP first(i have vista upgrade) then installed Vista Flawlessly.
After about 20min of installing drivers ect it froze.Lost Power to USB devices and had to restart.
This happend once or twice more, then worked for the rest of the night.
I updated all Vista and drivers.
Even played "crysis" with all graph settings on very high without a problem.
Next day it began to freeze every time i booted windows(within 1-5min of seeing vista GUI)
It also restarted it self 1-2 times after seeing motherboard image on boot up. Then froze just before "verifying DMI pool Data".But after another restart, ran thru to windows and froze again.
I formatted it and took off "raid 0" wich i was running.
Strang thing was it did its usal freeze 1-2 times then ran perfectly that night.But next day surpirse suprise now does one of the two freezes mentioned above every time.
Cleared cmos then it worked, for 1 night...then same prob, didnt think of it then but later cleared again and worked again.Could this be the issue?
I have tried using UBCD(ultimate boot cd) and Memtest86, but am presented the error "could not find kernal image:linux" thru some trouble shooting ive found this error could be to do with the motherboard.
i believe the key symtons are:
1.Reseting itself pre windows, after Mother board image.
2.Freezing just before Verifying DMI pool Data
3.Losing power to USB devices when frozen.
4.Time where it is error free to just end up freezing again.
5. Clearing cmos grants temp functionality
After more freezing, tested diff memory, same prob, reset cmos and works, just like before

I am Completely Stumped, Any Help would be much Apreciated
Thanks in advance Michael
