Windows 7 giving BSOD after installing XP

[Imperial_Raj]

Hello everyone! I had Windows 7 pre-installed on my new PC. I installed Ubuntu on it and ran the system in dual-boot for some time. I removed Ubuntu after some time and repaired the bootloader. But it still showed Ubuntu as an option.
Now, yesterday I installed XP to run my printer (which had XP-only drivers and 7 drivers wouldn't run). Now my PC booted up directly into XP. So, to get 7 back, I repaired its bootloader just like I had done after removing Ubuntu. Now, the bootloader shows 7 and Ubuntu but no option for XP is found. Also, when I select 7, a BSOD shows for a millisecond and the computer shuts down. I have repairing the startup when asked but in vain.
So I guess I'm quite in a great fix now and need your valuable help and advices to recover my normal PC startup. I have already downloaded EasyBCD 2.1 so as soon as the PC will boot into XP, I'll use it to get the desirable boot entries.

I'm really in a fix now as I need my PC for work but it isn't just starting up. I seriously need your help and advices on how to getting into any of the two OS's safely to get my PC running back up again.
Thanks.

Try refitting all the RAM and also scan your HDD for errors

also do a cleanup using CCleaner

Download CCleaner 3.10.1525 - FileHippo.com


Defragment Drives to see if it helps
