virtual memory low

You can increase the Virtual memory on your machine.

1.  Open System in Control Panel.
 
2.  On the Advanced tab, under Performance, click Settings.
 
3.  On the Advanced tab, under Virtual memory, click Change.
 
4.  Under Drive [Volume Label], click the drive that contains the paging file you want to change.
 
5.  Under Paging file size for selected drive, click Custom size, and type a new paging file size in megabytes in the Initial size (MB) or Maximum size (MB) box, and then click Set.

you can also install more Ram since you have a 64-bit OS
6 or 8GB would be nice..
but check if the mobo supports it
you can use the ram search :    http://www.kingston.com/us/memory/search/options/

With 4 gigs of ram the recommended size of your paging file (virtual memory) is about 6 gigs.

Create a static paging file. To do this set the maximum and minimum to the same value (6000 min & 6000 max) or (7000 min & 7000 max). Restart, then defragment the drive.

A static paging file is always recommended to reduce disk defragmentation.

I agree with Eirman - Not to use Windows automatic sizing, but to fix the minimum and maximum size of the paging to the same 150% of actual RAM.

If you have a second hard disk, set the paging size to 0 on the C: drive, and SET, then set the 6000 MB min/max on another drive and SET, then APPLY, Reboot (wait) and see if this helps.

If you right click on My Computer, select "Manage" and look at disk storage, see if your C: drive is one or two partitions. After defragging it, you MIGHT be able to reduce the partition size, making part of the drive an unused partition. Then add a partition to the unused disk space, format it with NTFS, give it a drive letter, and make that your Paging/Swap file location. I've done that on new systems, but you may not have enough free and unused disk drive space.

Add more RAM too, it will make everything run faster. Make the paging file min and max 1.5x the size of your RAM.

I MADE IT MINIMUM 3500
MAXIMUM 4000

Please advice if it is correct , also i am facing problem with this pc is its getting heatup very soon.and slowdowns and then keep showing vertual memory low popup.
Kindly Advice .

your System have 4GB memory.. i will suggest to
set to maximum around 6 Gb..

Minimum 6000
Maximum 6000

1.5 x the size of your actual RAM

This stops Windows from fiddling around with the file. If it changes sizes, it has to allocate and deallocate blocks from disk. A fixed size can be allocated once, and hopefully the file itself is not fragmented.

If it's a laptop, get a laptop cooler immediately. Video pushes the processor to 100% use, and can quickly overheat a laptop.

thanks

what was the problem / solution?
