I have a PC with Windows 7 OS which is having problem booting up. It runs “DOS” check disk and does not complete it and does not boot. By accident I changed the vendor's boot to USB and it booted the OS. I have been unsuccessful changing the setup to boot to USB. The boot precess runs differently each time I try that and never completes. So it looks like MBR on the HD is kaput. Since I am new to Windows 7 I hope I can get to DOS fdisk and restore the MBR.
Or is there any other newfangled way to to this in Windows 7?
At one point the OS start running “automatic updates” , but started with #40 out of 72. My guess is that the original update got interrupted and the result is no boot record on HD. BTW , for 64 bit OS it is painfully slow, but I do not look given horse into mouth. Thanks for your help. Vaclav
My laptop is an Acer Extensa 5630Z that currently has 3GB of RAM. That page says I can only uprade to 4GB, but I wonder if that was just a hypothetical maximum, perhaps based on the largest RAM modules available when I bought my laptop. My question is if I could install, say, two of these 4GB sticks for a total of 8GB. My laptop is 64-bit capable, and that RAM is the proper type, so I don't see why there would be an arbitrary limit of 4GB (assuming I install Windows 7 64-bit).
I first tried to ask Acer over a chat if this would be possible, but let's just say I don't have much confidence in the support person's knowledge (he indicated 4GB is the max). Here is the shortened conversation for your review and amusement:
Me: I was considering buying some RAM for my Acer Extensa 5630Z. I was curious if there were any limitations of the size I could install. For example, could I get 2 PC-5300 DIMMs that are each 4GB (for a total of 8GB)? Me: Just as an example, I found some RAM on NewEgg with the description "G.SKILL 4GB 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Laptop Memory". I was thinking of buying 2 of those. Him: You can upgrade up to maximum of 4 GB. Him: Up to 2 GB of DDR2 667 MHz memory, upgradable to 4 GB using two soDIMM modules. Me: Is that a limitation of the other hardware in the laptop, or was that just the largest amount of memory that was tested, or is that a software limitation? Him: It will tested with maximum memory, and the system performance will affect, if you exceed the maximum memory. Him: You can upgrade up to 4 GB RAM. Me: OK, I just want to be sure there's no chance I could upgrade to 6GB or 8GB. I thought perhaps this type of RAM may not have been available when my laptop was made. Do you know that level of detail? Him: I am sure, your system will compatible up to 4 GB up gradation only.
Have any idea of whether or not I should be able to do more than a "4 GB up gradation"?
Good news and bad news. According to this, the chipset supports 8GB. However, it also says "256-Mb, 512-Mb, 1-Gb, and 2-Gb memory technologies supported". So if the motherboard had 4 RAM slots, maybe it would allow for 8GB, but since there are only 2 slots, maybe it only allows for 4GB. Though, again, I run into the possibility that the largest RAM of this type may have been 2GB when this document was created.
Anyone know how to properly declutter a window 7 laptop. Ive done the Disk Cleanup (inclduing former restore points), defragged and run Piriform CCleaner.
I've found one directory online that got a few meg, but all I can free up is 12.5 G on an 80G disk.
Now I do have the RC for Visual Studio 2012 installed along side VS2008, but that would account for no more than 10G. One or other may have to go but I would prefer to retain 08 until 12 settles in. If pushed 12 gets it!
Looking over the drive using Winzip Utilities, the real perpetrators are thousands of small files that appear to be related to various automatic updates. I tried removing some of them but that caused chaos. The machine is over 4 years old, and was upgraded from Vista to 7 about 15 months ago.
you can use tools like WinDirStats to find where the bulk of you storage is being used. That is always a good starting point. I would also recommend checking to see what processes are running and what programs are installed. Then ask yourself if you still use the programs and if not, remove them. Maybe more your documents and music and such to an external drive.
I would love to change the world, but they won't give me the sourcecode....
Hello all. We developed an app that interacts with Facebook, by posting data to a specific account. This is done by establishing an HTTP request. In my server, this works perfectly. However, when I go to out customer's, it simply won't work.
I know that this guys have very tight security measures. One of those consist on blocking anything to do with Facebook. Now, we requested that for that server and a specific account to be free of such policies. They did so, and when opening the IE, they can connect to Facebook's main page. However, our program still throws a 400 Bad Request.
So I'm wondering if there is anything else blocking such connections. To that end, I downloaded Microsoft Network Monitor 3 and SysInternals TCPView. However, neither shred a light on the situation, other than showing which connections are made.
Thus my question: is there any tool out there that can be used to trace an HTTP connection and then detect where it is being blocked either by a policy or by a firewall? Or a clue on to what could be happening?
Wireshark[^] will show you what's happening "on the wire". If it's local policy, you won't see anything. If it's a firewall, you'll see the 400 coming back. A clue to where it came from would be in the response time - the faster the response, the closer the rejection.
