4gb of RAM installed, but w7 says 256 usable

Earlier tonight I rebooted and noticed that it took an extremely long time to boot. Almost 10 minutes to get the desktop completely loaded. So I checked task manager > performance tab and it says I have only 256mb of RAM. So then I checked My Computer > Properties and noticed it said "Installed Memory (RAM): 4.00 GB (256 MB Usable)" I've had w7 installed for a good 2 weeks now and never had a problem, until I rebooted tonight. I checked my BIOS and all my sticks show up. I DO NOT have a shared memory video card. Memory test checked out fine. I haven't installed any new hardware, nor touched the sticks at all. Any idea as to why w7 started doing this?

Nope. I managed to find and fix the problem tho. Somehow the MAX ram settings in the advanced tab of boot config got set to 256mb. I unchecked the box, rebooted and everything is fine now.

I recently had this same exact problem and this solution worked. My Computer started up REALLY slow after it got turned off by a storm and the maximum memory in MSCONFIG>BOOT>ADVANCED OPTIONS was at 256. I brought it back up to 8000 and my comp is back to normal. You can tell how much memory is usable by right-clicking computer and selecting properties. This post solved my problem, hope it solves someone elses too
