Win xp system loading problem

Hello, I'm having a problem with my pc. I turned my pc on and received a message about data compactness test or sth like that. I usually skip this test but this time i decided to wait and see what the problem was, it was quick save game file and it was fixed in step two. After the step 3 of 3 there was another action this time concerning some libraries (not sure if erasing them or else). It was taking too long so i cut the power off, after i did that and turned pc on again boot menu appeared all of sudden. I chose to run windows normally, the loading bar appeared normally, unfortunately, few seconds later blue screen appeared and it was displayed too short for me to read, just a blink of an eye, then my pc rebooted unreasonably. I tried safe mode and system restoring but it failed in the same moment prompting the same thing. My processor is pentium IV, service pack 3. I'd be grateful if you could hint me what to do, thanks!
