Windows 7 is freezing. I have had it freeze while watching youtube. It freezes mostly right after I have logged in and its loading the startup programs. It is freezing all the time when I run Starcraft 2. Starcraft 2 can be in campaign mode, multiplayer mode, or just in the menue and it will freeze. The only way out of it is a hard reset in any of the cases. Usually what happens is I run starcraft 2 and it freezes about 5 to 10 mins in. I do a hard reset and then it freezes after login when it is loading up. Then I do another hard reset and it runs fine again.... well until i run starcraft 2 or it just decides to freeze on me. My keyboard's lcd screen shows that one of the cores of my cpu maxes out everytime it freezes while the other 3 cores are running normally or not at all. I am thinking its a windows problem or a hardware problem and not a problem with starcraft 2. It just happens with starcraft 2 100% of the time. I have updated all of my drivers. Win 7 is up to date. all virus software is up to date and runs weekly. I have tried reinstalling sc2... still freezes. It has been doing this since Saturday. The one change i made was I installed an additional 500gb wd blue hdd for more backup space. Please any help or ideas you could give me would be grately apreciated.

specs:
win 7 64bit
intel ssd 75gb
gtx 470
rampage 2 extreme mobo
intel i7 920 @ 4ghz (water cooled)
6gb corsair ram
HDDs: WD 500gb, WD 250gb, WD 500gb blue(new one)
850w thermaltake ps

no errors. I ran it for over an hour @ 4 memtests running.

Should i update my bios? I have been told to never do that. If so would I have to redo my overclock?

I installed a 500gb west digital blue hdd. And then the freezing started happening. I uninstalled the hard drive and unplugged it from the mobo and it still froze so i am not so sure that is the problem. I just am at a loss with this one.

So I am still trying to figure this problem out and pin point it. Starcraft 2 is consistantly freezing shortly after starting any game type. I am forced to either turn my comp off or do a hard reset. After the reset, windows 7 freezes after I log into it and during startup of the programs. I then have to do another reboot and then everything is back to normal. I have turned the sc2 settings all the way down and turned the sound off and sc2 will still freeze in a game.

now that the RAM seems to be working out.
i know that you don't want to hear this but you need to start clean...
full reformat and clean install with active internet connection so windows installer can download packages and drivers..
let windows detect and install everything, do not install any software from disk.
whatever the installer doesn't update then windows updates will find upon booting into windows..

Ok i know it has been a while. sorry i got busy. So i just reinstalled win 7 64 bit after I formated the ssd. Starcraft 2 is still freezing like 5 - 10 mins after i start it and in any mode. So its the same issue. Running starcraft my cpu temps never get over 60c. Do you think it could be a video card problem or is a 59c temp cuasing it to freeze up? Oh and i let win7 install everythign on its own. except for the logitech game panel and set point.

a little of malmental's info and finds on SSD:

Performance Degradation Over Time, Wear, and Trim

As mentioned above, flash blocks and cells need to be erased before new bytes can be written to them. As a result, newly purchased devices (with all flash blocks pre-erased) can perform notably better at purchase time than after considerable use. While we’ve observed this performance degradation ourselves, we do not consider this to be a show stopper. In fact, except via benchmarking measurements, we don’t expect users to notice the drop during normal use.

Of course, device manufactures and Microsoft want to maintain superior performance characteristics as best we can. One can easily imagine the better SSD manufacturers attempting to overcome the aging issues by pre-erasing blocks so the performance penalty is largely unrealized during normal use, or by maintaining a large enough spare area to store short bursts of writes. SSD drives designed for the enterprise may have as high as 50% of their space reserved in order to provide lengthy periods of high sustained write performance.

In addition to the above, Microsoft and SSD manufacturers are adopting the Trim operation. In Windows 7, if an SSD reports it supports the Trim attribute of the ATA protocol’s Data Set Management command, the NTFS file system will request the ATA driver to issue the new operation to the device when files are deleted and it is safe to erase the SSD pages backing the files. With this information, an SSD can plan to erase the relevant blocks opportunistically (and lazily) in the hope that subsequent writes will not require a blocking erase operation since erased pages are available for reuse.

As an added benefit, the Trim operation can help SSDs reduce wear by eliminating the need for many merge operations to occur. As an example, consider a single 128 KB SSD block that contained a 128 KB file. If the file is deleted and a Trim operation is requested, then the SSD can avoid having to mix bytes from the SSD block with any other bytes that are subsequently written to that block. This reduces wear.

Windows 7 requests the Trim operation for more than just file delete operations. The Trim operation is fully integrated with partition- and volume-level commands like Format and Delete, with file system commands relating to truncate and compression, and with the System Restore (aka Volume Snapshot) feature.
Windows 7 Optimizations and Default Behavior Summary

As noted above, all of today’s SSDs have considerable work to do when presented with disk writes and disk flushes. Windows 7 tends to perform well on today’s SSDs, in part, because we made many engineering changes to reduce the frequency of writes and flushes. This benefits traditional HDDs as well, but is particularly helpful on today’s SSDs.

Windows 7 will disable disk defragmentation on SSD system drives. Because SSDs perform extremely well on random read operations, defragmenting files isn’t helpful enough to warrant the added disk writing defragmentation produces. The FAQ section below has some additional details.

Be default, Windows 7 will disable Superfetch, ReadyBoost, as well as boot and application launch prefetching on SSDs with good random read, random write and flush performance. These technologies were all designed to improve performance on traditional HDDs, where random read performance could easily be a major bottleneck. See the FAQ section for more details.

Since SSDs tend to perform at their best when the operating system’s partitions are created with the SSD’s alignment needs in mind, all of the partition-creating tools in Windows 7 place newly created partitions with the appropriate alignment.
Frequently Asked Questions

Before addressing some frequently asked questions, we’d like to remind everyone that we believe the future of SSDs in mobile and desktop PCs (as well as enterprise servers) looks very bright to us. SSDs can deliver on the promise of improved performance, more consistent responsiveness, increased battery life, superior ruggedness, quicker startup times, and noise and vibration reductions. With prices steadily dropping and quality on the rise, we expect more and more PCs to be sold with SSDs in place of traditional rotating HDDs. With that in mind, we focused an appropriate amount of our engineering efforts towards insuring Windows 7 users have great experiences on SSDs.

Will Windows 7 support Trim?

Yes. See the above section for details.

Will disk defragmentation be disabled by default on SSDs?

Yes. The automatic scheduling of defragmentation will exclude partitions on devices that declare themselves as SSDs. Additionally, if the system disk has random read performance characteristics above the threshold of 8 MB/sec, then it too will be excluded. The threshold was determined by internal analysis.

The random read threshold test was added to the final product to address the fact that few SSDs on the market today properly identify themselves as SSDs. 8 MB/sec is a relatively conservative rate. While none of our tested HDDs could approach 8 MB/sec, all of our tested SSDs exceeded that threshold. SSD performance ranged between 11 MB/sec and 130 MB/sec. Of the 182 HDDs tested, only 6 configurations managed to exceed 2 MB/sec on our random read test. The other 176 ranged between 0.8 MB/sec and 1.6 MB/sec.

Will Superfetch be disabled on SSDs?

Yes, for most systems with SSDs.

If the system disk is an SSD, and the SSD performs adequately on random reads and doesn’t have glaring performance issues with random writes or flushes, then Superfetch, boot prefetching, application launch prefetching, ReadyBoost and ReadDrive will all be disabled.

Initially, we had configured all of these features to be off on all SSDs, but we encountered sizable performance regressions on some systems. In root causing those regressions, we found that some first generation SSDs had severe enough random write and flush problems that ultimately lead to disk reads being blocked for long periods of time. With Superfetch and other prefetching re-enabled, performance on key scenarios was markedly improved.

Is NTFS Compression of Files and Directories recommended on SSDs?

Compressing files help save space, but the effort of compressing and decompressing requires extra CPU cycles and therefore power on mobile systems. That said, for infrequently modified directories and files, compression is a fine way to conserve valuable SSD space and can be a good tradeoff if space is truly a premium.

We do not, however, recommend compressing files or directories that will be written to with great frequency. Your Documents directory and files are likely to be fine, but temporary internet directories or mail folder directories aren’t such a good idea because they get large number of file writes in bursts.

Does the Windows Search Indexer operate differently on SSDs?

No.

Is Bitlocker’s encryption process optimized to work on SSDs?

Yes, on NTFS. When Bitlocker is first configured on a partition, the entire partition is read, encrypted and written back out. As this is done, the NTFS file system will issue Trim commands to help the SSD optimize its behavior.

We do encourage users concerned about their data privacy and protection to enable Bitlocker on their drives, including SSDs.

Does Media Center do anything special when configured on SSDs?

No. While SSDs do have advantages over traditional HDDs, SSDs are more costly per GB than their HDD counterparts. For most users, a HDD optimized for media recording is a better choice, as media recording and playback workloads are largely sequential in nature.

Does Write Caching make sense on SSDs and does Windows 7 do anything special if an SSD supports write caching?

Some SSD manufacturers including RAM in their devices for more than just their control logic; they are mimicking the behavior of traditional disks by caching writes, and possibly reads. For devices that do cache writes in volatile memory, Windows 7 expects flush commands and write-ordering to be preserved to at least the same degree as traditional rotating disks. Additionally, Windows 7 expects user settings that disable write caching to be honored by write caching SSDs just as they are on traditional disks.

Do RAID configurations make sense with SSDs?

Yes. The reliability and performance benefits one can obtain via HDD RAID configurations can be had with SSD RAID configurations.

Should the pagefile be placed on SSDs?

Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well.

In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that

* Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1,
* Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB.
* Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size.

In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD.

Are there any concerns regarding the Hibernate file and SSDs?

No, hiberfile.sys is written to and read from sequentially and in large chunks, and thus can be placed on either HDDs or SSDs.

What Windows Experience Index changes were made to address SSD performance characteristics?

In Windows 7, there are new random read, random write and flush assessments. Better SSDs can score above 6.5 all the way to 7.9. To be included in that range, an SSD has to have outstanding random read rates and be resilient to flush and random write workloads.

In the Beta timeframe of Windows 7, there was a capping of scores at 1.9, 2.9 or the like if a disk (SSD or HDD) didn’t perform adequately when confronted with our random write and flush assessments. Feedback on this was pretty consistent, with most feeling the level of capping to be excessive. As a result, we now simply restrict SSDs with performance issues from joining the newly added 6.0+ and 7.0+ ranges. SSDs that are not solid performers across all assessments effectively get scored in a manner similar to what they would have been in Windows Vista, gaining no Win7 boost for great random read performance.

there's a saying, if it's not broke then don't fix it.
but there are cases in which updating the BIOS can be helpful.
there should be a description of the exact BIOS enhancements for each update, look carefully at those.
I guess what I am saying is that sometimes it can be a good thing..

After the reboot my comp froze again after i entered my pw and before going to desktop. rebooted again... this time i got into windows but the graphics resolution was messed up.

Check the event viewer for errors.
start-->run-->eventvwr.msc-->look at the system and application logs for errors (red X's).

Look at the date/time of the error, and find the ones that correspond to the freezing.

Double check to make sure you have the latest video driver.

Then look up your RAM, and find the factory timings and voltage settings. Then download, and run CPUZ, and verify that your settings are correct. If not, adjust them in the BIOS.

Try running in safe mode with networking for a while. Does the problem follow you there?

Look at scenerio 3, at the bottom of the link. Most of the possible causes have been ruled out, except the power supply. Thermaltake aren't known to be the greatest quality. Maybe swap in a better PSU, or a lower powered video card (helps ease the demand on the PSU).
