My copmuter is a Dell Dimension XPS R400.
I have, over the last year, added some hard-ware:
another stick of RAM for a total of 224 mb (64+32+128)
a new Graphic Card (Geforce 2 MX 200 64mb by Power color)
another Harddrive (Maxtor 10 gb)
a sound card (some form of boxless Audigy from Ubid)
I started receiving blue screens with seemingly random errors such as "KERNAL_STACK_IN_PAGE_ERROR". I also received an error with the WIN2K/XP Partition Manager, "PartMgr.sys".
Could it be that the computer is overheating? It is on most of the time. It does have a UPS, but I didn't connect the UPS to the Serial Port.
Also, after getting such an error, the computer claims that an "Operating System not found". Right now it gives a blue screen that says "UNMOUNTABLE_BOOT_VOLUME".
As I am planning to upgrade the motherboard and CPU soon, should I invest in some bigger fans and cooling compound, or in a bigger PSU?
Edit 1: I am writing this on a diffrent computer.
