Need help quick! Since August 17 Ive been getting BSOD, first stop error message was 0x00000077A then I was told it was because I didnt have enough memory to run everything, only had 256mb, also said that using AOL was really bad, big resource hog. So I removed the 256mb ram stick and had two new 512mb ram sticks installed. Now havent had any more 0x00000077A but have had two blue screens saying 0x000000F4 somethng about a crucial thread? my hard drive is 2 yrs old, short tests say its ok but it makes this random ticking noise for about 1 minute then goes away. Im assuming its the HHD. but my DVD ROM had a disc stuck in it and now every once in awhile I get a little copy of a CD on my mouse pointer like its trying to load up, maybe that? I ran a hard drive diagnostics using Speed Fan and HD Tune and this is what it said. NOTE: not all warnings are reflected on fitness and performance overall values as relevancy is based upon the settings from the hard disk manufacturer who is the best entity deputed to define such relationships. NOTE : your hard disk has 384 reallocated sectors (this value is very large and your hard disk should be replaced). Hard disks do have spare sectors (usually from 256 up to 1024) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degradated performances (because remapped sectors are in different places of the disk than the original ones and the head needs additional moving). If reallocated sectors grow over time, you might encounter some serious troubles. A backup of the most important data is suggested anyway. NOTE : your hard disk has 1 pending sectors. Those are sectors that couldn't be properly read and that the hard disk logic is waiting for a write operation to try to remap to a spare sector (if available). According to the Reallocated Sector Count attribute, your hard disk seems to have available spare sectors. A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data. NOTE : your hard disk Spin Retry Count attribute current value (248) is below the normal range (252 - 253) reported for your specific hard disk model. This means that your hard disk was unable to start the motor at the first attempt and that additional retries were needed. This is not a good sign and you should keep an eye on your hard disk. The overall fitness for this drive is 22%. The overall performance for this drive is 86%. Ok do you think this is the cuase of my BSOD? if not what else can I do to find out whats causing this? seems like it only happens when my PC sits idle, not when its being used. My HHD temp is running around 41c, manufacturer says it should normally be about 36c. Can anyone help!
