Vista Boot errors

[m45h]

Hi people

I have been having a very bad boot problem lately its been around 2 weeks now and now its taking a right mickey

So every time i Boot my computer it load and logs me in after a little while it just restarts automatically
After it restarts it won't log me in also the screen would just stay blank i have to keep on switching it on and off at least for 1 hour till it would start up properly i also get this blue screen error

STOP: 0x000000A5

My hardware is this

Intel Pentium D
2Gb RAM DDR2
250Gb Hard drive (this has been partitioned to 150Gb and 100Gb)
My motherboad can be found here

So please can anyone help me I now cant even login or access safe mode when trying to get in to safe mode it loads some files and get stuck at crcdisk.exe

Can it be a Hardware problem?

Thanks for your time

It would seem that you may need to udate your BIOS or your board may not run Vista.
Check with your MB maker and or the Vista Hardware Compatability List for Vista.
Below is a link that helps to explain the problem.
