Good day all First off, been a while since I've posted here. Been working constantly the past year and it is a shame I haven't been as active as usual. I'm here today with an issue that I've tried loads of stuff and I'm stumped as how to fix it. The issue being that when I came back from leave I went on my PC at work and it was having issues downloading games on steam. At first I thought internet was dodgy and I reset the router here at work and it didn't fix it at all. Laptop was downloading fine. So I thought hard drive issue and re-installed on a different drive. Issue persisted. Changed the image I was using of windows 7 x64. No difference Ran MemTest. No RAM issues. Lowered speed to DDR3 1066mhz and reverted to stock. No difference Reinstalled 3-4 times, no difference. Absolutely and completely at a loss on what the issue is. I'm beginning to think the motherboard is the issue but I have no way to test it. I also have limited resources in changing parts or sending stuff away for an RMA. Picture one is errors that happen in steam. It also occurs with anything to do with unzipping and extracting files. The second image of steam is what happens in chrome that web pages do not load properly and often images do not display correctly and often have random colours through them making them look corrupted.
