How do I fix Cydia's problem with refreshing?

How do i fix my BSoD problem?

• OK so just in the last few weeks I've been getting several bsods after months of smooth running. the error code is 7a, which as far as i can tell is hard drive related, and could be a failing hard drive. the problem is I've had this same problem before on the same type of hard drive (seagate barracuda) a few months earlier. hard drives don't just fail this often randomly, so there must be something wrong in my system so i have a p5k se motherboard, 650w power supply, gtx 275 graphics card, and a seagate barracuda hard drive as mentioned earlier. my ram is 4gb, consisting of two 2gb sticks, one apacer and the other kingston (is this mismatching RAM my problem?). both sticks of RAM are supported by the motherboard, but does having them both in cause the hard drive to fail? i've tried a disk check and that hasnt fixed it I've tried memtest86 to see if my ram is faulty, but no issue have been found so still unable to fix my problem another thing which could be useful to mention is that just before the bsod, the hard drive makes a clicking sound, and the computer freezes i realise that once again my hard drive is dying and i should back up my data as soon as i can, i just whan to know what is causing this problem and how it can be fixed. if you need additional data on the error that shows up let me know cheers

  Blue screen of death, as its name describe, is one of the toughest errors that you can confront as a Windows user.One term which may cause this symptom is called a crowded windows registry.The Windows operating system always refers to the registry to fetch information about all of the components such as hardware and software which are installed on the computer. The registry tells Windows what to do and how to access the different programs, files, and processes.However, the registry can contain bad info which makes Windows taking useless tasks or running unnecessary routines. Sometimes errors occur including the blue screen of death. Other times the system slows down. Because of the numerous factors that can involve the registry, there's no one size fits all approach. You can't just go into the registry and remove the bad data because it's nearly impossible to detect which info is good and which one is bad.The main objective of a registry cleaner is to eliminate the unneeded items from the windows registry to ensure your computer will keep running faster and with fewer errors. http://cleanup-comuter-run-perfectly.com
