Gateway GM5661e Windows Vista Home Premium Intel® Core™2 E4500 dual core processor •Installed: 3072 MB DDR2, 667 MHz, (PC2-5300) dual channel memory 500 GB, 7200 RPM, SATA II hard drive All appears normal, but after touching the mouse the problems are apparent. The mouse freezes all over the screen. I have to do a large sweep and then tiny micro-movements to select and icon. The programs load super slow and the mouse is skipping all over the screen. When the Pc is turned on the gateway screen is on for over a minute then the monitor turns off and then back on the loading bar pauses many times as it starts up. It eventually loads, but then the mouse doesn't move. The pc makes a grinding, clicking sound when the mouse moves, but then the mouse freezes and the noise stops. I am at a loss for words. I have been through a lot with this pc from last month when it stopped turning on. It has come a long way and I feel like it am almost done, but something isn't right. I am hoping it is not the motherboard, but I cannot think of anything else it could be. These are the steps i have taken to fix my pc. Checked PC to make sure drivers were up to date. Defragged the hard-drive registry cleaner Removed all dust replaced thermal paste on cpu Did a recovery that formatted the hard drive and reinstalled the OS Installed Antec PSU Replaced CPU Fan Opened safemode and mouse still freezes It seems that as soon as the Pc starts the problem is already at work. It all started after I install some phone software, but after the format I would think if it was a software issue it would have been resolved. Thanks for any help you can offer.
